Description

  The present invention relates to a spectrum display device, a spectrum display method, and a program.

  In X-ray analysis such as fluorescent X-ray analysis and mass spectrometry, a waveform spectrum is obtained as a measurement result. In a display device for displaying such a waveform spectrum, it is important to display so that information obtained from the waveform spectrum can be easily grasped. For example, Patent Document 1 discloses a display device that makes it easy for a user to confirm important points with many peaks by changing the scroll speed according to the weight of the peaks included in the spectrum.

  Conventionally, when displaying the peak of interest from the waveform spectrum obtained by fluorescent X-ray analysis, etc., the peak of interest is extended by displaying the peak other than the peak of interest and its vicinity. It was displayed.

  FIG. 18 is a diagram illustrating an example of a waveform spectrum showing a continuous energy distribution. When attention is paid to the peak a1 in the waveform spectrum, the energy range a2 including the peak a1 is designated, and only the energy range a2 is displayed. As a result, as shown in FIG. It is displayed in an expanded manner, and the details of the peak a1 can be confirmed.

  However, in the display methods shown in FIGS. 18 and 19, either the entire waveform spectrum is displayed or a partial energy range is expanded and displayed.

  FIG. 20 is an example of a waveform spectrum obtained by fluorescent X-ray analysis. This waveform spectrum includes information on Sn (tin) and includes a peak indicating the energy of Sn. Specifically, the waveform spectrum shown in FIG. 20 includes the α and β peaks of the Sn L line on the low frequency side, and the α and β peaks of the Sn K line on the high frequency side.

  In this waveform spectrum, in order to observe the Sn K-line, the energy range b1 including the Sn K-line is selected and extended in the example of FIG. At this time, for example, only the energy range b1 is displayed in the display region b, and the energy range b3 including the Sn L line and the energy range b4 higher than the energy range b1 are not displayed. For this reason, in order to confirm the spectrum of the energy ranges b3 and b4 other than the energy range b1, it is necessary to display the entire waveform spectrum again or change the display range.

  FIG. 21 is an example of a waveform spectrum obtained by fluorescent X-ray analysis. In the spectrum shown in FIG. 21, the energy range c1 is selected to observe both the peak of Sn L line and K line, and the waveform spectrum of the energy range c1 is expanded. As shown in FIG. 21, even if the lower range than the energy range c2 including the Sn L-line peak and the range higher than the range c3 including the Sn K-line peak are deleted, the display is performed. Since the waveform spectrum included includes the energy range c4 including the unnecessary waveform spectrum between the energy range c2 and the energy range c3, the waveform spectrum included in the target ranges c2 and c3 should be sufficiently expanded.

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. The embodiments described below do not unduly limit the contents of the present invention described in the claims. Also, not all of the configurations described below are essential constituent requirements of the present invention.

1. 1. First embodiment 1.1. Configuration of Spectrum Display Device First, the spectrum display device according to the first embodiment will be described. FIG. 1 is a diagram illustrating an example of a configuration of a spectrum display device 100 according to the present embodiment.

  The spectrum display device 100 is a device for enlarging (expanding) and displaying a part of a spectrum in which a first axis is a predetermined physical quantity and a second axis is an intensity with respect to the predetermined physical quantity. Here, the spectrum to be processed by the spectrum display device 100 is, for example, a waveform spectrum. The waveform spectrum indicates, for example, a continuous energy intensity distribution. Examples of the spectrum to be processed include a fluorescent X-ray spectrum obtained as a result of fluorescent X-ray analysis, a mass spectrum obtained as a result of mass analysis, a spectrum obtained as a result of X-ray diffraction, and the like.

  The spectrum of fluorescent X-rays is, for example, a spectrum in which the first axis (horizontal axis) is the energy of fluorescent X-rays and the second axis (vertical axis) is the intensity with respect to the energy of fluorescent X-rays. The mass spectrum is, for example, a spectrum in which the first axis (horizontal axis) is mass (mass-to-charge ratio) and the second axis (vertical axis) is intensity relative to mass (mass-to-charge ratio). Hereinafter, the case where a spectrum of fluorescent X-rays is used as a spectrum to be processed by the spectrum display device 100 will be described, but the present invention is not limited to this.

  As shown in FIG. 1, the spectrum display device 100 includes an operation unit 10, a processing unit 20, and a display unit 30. The spectrum display device 100 can further include a storage unit 32 and an information storage medium 34.

  The operation unit 10 is for the user to input operation information, and outputs the input operation information to the processing unit 20 (interface unit 21). For example, the operation unit 10 is used by the user to specify the range (enlarged range) of the energy axis of the spectrum. The functions of the operation unit 10 can be realized by hardware such as a keyboard 12, a mouse 14, and a touch panel 16. For example, the display unit 30 may include the touch panel 16. The user can designate an arbitrary position of the spectrum displayed on the display unit 30 by performing an operation of bringing a fingertip (or a touch pen) into contact with the touch panel 16.

  The processing unit 20 includes a range information acquisition unit 22 and an image generation unit 24. The processing unit 20 can further include an interface unit 21, a range information storage unit 23, a spectrum extraction unit 25, and a display processing unit 27. The functions of the processing unit 20 can be realized by hardware such as various processors (CPU, DSP, etc.), ASIC (gate array, etc.), and programs.

  The interface unit 21 can receive operation information output from the operation unit 10.

  The range information acquisition unit 22 acquires enlarged range information I22 designated by the operation unit 10. Specifically, the range information acquisition unit 22 determines whether the operation information received by the interface unit 21 specifies a range (enlarged range) of the spectrum energy axis. When the range information acquisition unit 22 determines that the operation information specifies the range (enlarged range) of the energy axis of the spectrum, the range information acquisition unit 22 acquires the extended range information I22 from the operation information. The range information acquisition unit 22 outputs the acquired enlarged range information I22 to the range information storage unit 23.

  The range information storage unit 23 outputs the expanded range information I22 received from the range information acquisition unit 22 to the spectrum generation unit 24 in response to a request from the spectrum generation unit 24.

  The spectrum generation unit 24 expands the expansion range along the energy axis (first axis) at a predetermined expansion rate based on the expansion range information I22, and reduces the spectral range different from the expansion range to a predetermined reduction. Produces an expanded spectrum that is scaled down along the energy axis at a rate. The enlargement rate and reduction rate may be set in advance by the user, for example. The reduction ratio may be set so that the entire spectrum is displayed in the display area of the display unit 30 when the enlargement range is enlarged at a predetermined enlargement ratio.

  The spectrum generation unit 24 requests the range information storage unit 23 for the extended range information I22. In addition, the spectrum generation unit 24 requests the spectrum extraction unit 25 for spectrum data for generating an expanded spectrum. The spectrum generating unit 24 can generate an expanded spectrum based on the expanded range information I22 acquired from the range information storage unit 23 and the spectrum data acquired from the spectrum extracting unit 25.

  The spectrum generation unit 24 outputs the generated expanded spectrum to the display processing unit 27.

  The spectrum extraction unit 25 extracts, for example, spectrum data requested from the spectrum generation unit 24 from the spectrum data stored in the information storage medium 34 and outputs the spectrum data to the spectrum generation unit 24.

  The display processing unit 27 outputs information on the expanded spectrum generated by the spectrum generating unit 24 and display information other than the expanded spectrum (information such as a cursor and a marker described later) to the display unit 30.

  The display unit 30 displays an image generated by the processing unit 20, and its function can be realized by an LCD, a CRT, or the like. The display unit 30 can display the expanded spectrum and display information received from the display processing unit 27. The display unit 30 may include the touch panel 16.

  The storage unit 32 serves as a work area of the processing unit 20, and its function can be realized by a RAM or the like. The information storage medium 34 (computer-readable medium) stores programs, data, etc., and functions as an optical disk (CD, DVD), magneto-optical disk (MO), magnetic disk, hard disk, or memory. (ROM) or the like. The processing unit 20 performs various processes of the present embodiment based on a program stored in the information storage medium 34. The information storage medium 34 can store a program for causing a computer to function as each unit of the processing unit 20. The information storage medium 34 can store spectrum data.

1.2. Spectrum Generation Method According to First Embodiment Next, a spectrum generation method according to the first embodiment will be described. FIG. 2 is a flowchart for explaining processing of the spectrum display apparatus 100 as an example of a spectrum generation method according to the first embodiment. Hereinafter, the spectrum display device 100 shown in FIG. 1 and the flowchart shown in FIG. 2 will be described.

  (1) First, the range information acquisition unit 22 acquires information I22 on the expansion range of the spectrum energy axis (enlargement range information acquisition step S10).

  Specifically, first, the processing unit 20 causes the display unit 30 to display a spectrum to be processed.

  FIG. 3 is a diagram illustrating an example of a spectrum of fluorescent X-rays displayed on the display unit 30.

  As shown in FIG. 3, the spectrum to be processed is a spectrum in which the energy of fluorescent X-rays is represented on the horizontal axis (energy axis) and the intensity with respect to the energy of fluorescent X-rays is represented on the vertical axis.

  Here, the user operates the operation unit 10 to designate the range (enlarged range) of the energy axis from the spectrum displayed on the display unit 30. In the example of FIG. 3, the user has specified an energy range D1 including Sn-Lα line and Sn-Lβ line, and an energy range D2 including Sn-Kα line and Sn-Kβ line. For example, when the user specifies the range D1, the user uses the mouse 14 or the touch panel 16 to specify two points, the end on the low energy side of the range D1 and the end on the high energy side of the range D1. The same applies to the range D2. The operation information input by the user in this way is output to the interface unit 21 by the operation unit 10.

  Next, the interface unit 21 receives the operation information output by the operation unit 10 and outputs it to the range information acquisition unit 22. The range information acquisition unit 22 determines whether this operation information specifies a range (enlarged range) of the energy axis. When it is determined that the operation information specifies the energy axis range (enlarged range), the range information acquisition unit 22 acquires information I22 on the expanded range (range D1 and range D2) from the operation information. The range information acquisition unit 22 outputs the information I22 of the expansion ranges D1 and D2 to the range information storage unit 23.

  (2) Next, the spectrum generation unit 24 expands the expansion range along the energy axis at a predetermined expansion rate based on the information I22 of the expansion ranges D1 and D2, and a spectrum range different from the expansion range Generates an enlarged spectrum reduced along the energy axis at a predetermined reduction rate (enlarged spectrum generation step S12).

  Specifically, the spectrum generation unit 24 requests the information I22 of the expanded ranges D1 and D2 from the range information storage unit 23. Then, the spectrum generation unit 24 expands the expanded ranges D1 and D2 along the energy axis at a predetermined magnification based on the information of the expanded ranges D1 and D2, and is a range D3 different from the expanded ranges D1 and D2. , D4, and D5 generate an expanded spectrum reduced along the energy axis at a predetermined reduction rate.

  The spectrum generation unit 24 may request the spectrum extraction unit 25 for spectrum data for generating an expanded spectrum. The spectrum generation unit 24 may generate an expanded spectrum based on the information I22 of the expanded ranges D1 and D2 acquired from the range information storage unit 23 and the spectrum data acquired from the spectrum extracting unit 25. A method for generating an expanded spectrum in the spectrum generation unit 24 will be described later.

  FIG. 4 is a diagram illustrating an example of an expanded spectrum generated by the spectrum generation unit 24. In the expanded spectrum shown in FIG. 4, compared with the spectrum to be processed shown in FIG. 3, the expanded ranges D1, D2 are expanded along the energy axis, and the ranges D3, D4, D5 different from the expanded ranges D1, D2 are energy. Reduced along the axis. For example, the spectrum generation unit 24 may adjust the reduction rate of the ranges D3, D4, and D5 to generate an enlarged spectrum that displays the entire spectrum in the display region of the display unit 30.

  Next, the spectrum generation unit 24 outputs the generated expanded spectrum to the display processing unit 27.

  (3) Next, the display unit 30 displays the expanded spectrum generated by the spectrum generation unit 24 (display step S14).

  Specifically, the display processing unit 27 outputs information on the expanded spectrum generated by the spectrum generation unit 24 to the display unit 30. For example, the display processing unit 27 may also output display information other than the expanded spectrum (information such as a cursor and a marker described later) to the display unit 30.

  Next, the display unit 30 displays the expanded spectrum and display information received from the display processing unit 27.

  The spectrum (enlarged spectrum) can be displayed by the above steps.

1.3. Here, an example of a method for generating an expanded spectrum in the spectrum generation unit 24 will be described.

  5 to 8 are diagrams for explaining an example of a method for generating an expanded spectrum in the spectrum generation unit 24. FIG.

  The spectrum generation unit 24 is enlarged along the energy axis at an enlargement rate in which an enlargement range is set, and a reduction in which a range different from the enlargement range (a range other than the enlargement range) is set as compared with the spectrum to be processed. Generate a spectrum (expanded spectrum) that is reduced along the energy axis at a rate. The enlargement ratio and reduction ratio can be arbitrarily set by the user, for example, and are recorded in the spectrum generation unit 24 in advance.

  In the example shown in FIG. 5, the enlargement ratio of the enlargement range is set so that the ratio of the region 31 a for displaying the spectrum included in the enlargement range is 80% of the entire display region 31 of the display unit 30. . The reduction ratio of the range different from the enlarged range 31a is set so that the ratio of the region 31b for displaying the spectrum included in the range is 20% of the entire display region 31.

  Here, as shown in FIG. 6, the case where there are two peaks α and β in the spectrum to be processed will be described. In FIG. 6, the X-axis direction is the energy axis, and the Y-axis direction is the intensity axis. When the user designates an energy range Dα including the peak α from the spectrum illustrated in FIG. 6, the spectrum generation unit 24 causes the spectrum included in the range Dα to occupy 80% of the display region 31 as illustrated in FIG. 7. A spectrum that is enlarged in the X-axis direction and reduced in the X-axis direction so that the spectrum included in the range other than the range Dα occupies 20% of the display region 31 is generated.

  A case will be described in which the user selects two ranges of the energy range Dα including the peak α and the energy range Dβ including the peak β from the spectrum illustrated in FIG. Here, the ratio of the range Dα to the range Dβ is 3: 2. At this time, the spectrum generation unit 24 is expanded in the X-axis direction so that the spectrum included in the range Dα occupies 48% of the display region 31, and the spectrum included in the range Dβ is displayed in the display region 31 as shown in FIG. An image that is enlarged in the X-axis direction so as to occupy 32% of the image and is reduced in the X-axis direction so that the spectrum included in the range other than the ranges Dα and Dβ occupies 20% of the display region 31 is generated. That is, when two ranges Dα and Dβ are designated, a region occupied by the spectrum included in the enlarged range (80% of the display region in the illustrated example) is distributed at the ratio of each range Dα and Dβ.

  In this way, the spectrum generator 24 can generate an expanded spectrum.

  According to the present embodiment, based on the expansion range information I22, the expansion range is expanded along the energy axis at a predetermined expansion rate, and the energy axis range different from the expansion range is the energy axis at the predetermined reduction rate. An expanded spectrum that is reduced along can be generated. Thereby, the energy range which a user pays attention to can be expanded and displayed on the display area of the display unit 30 while displaying the entire spectrum. That is, according to this embodiment, a spectrum can be displayed effectively. Therefore, the user can confirm in detail the range of interest while grasping the entire spectrum, and can efficiently obtain information from the spectrum.

  Furthermore, since the entire spectrum can be displayed in the display area of the display unit 30, for example, compared to the case where a part of the spectrum is enlarged and the other range is deleted and displayed, the display area in the spectrum is displayed. There is less need to perform an operation such as a change, and the amount of operation can be reduced.

2. Second Embodiment Next, a spectrum display device according to a second embodiment will be described. In the first embodiment, the user designates any two points on the energy axis of the spectrum displayed on the display unit 30 using the mouse 14 or the touch panel 16, thereby designating the expansion range. On the other hand, in the second embodiment, the user selects the element name displayed on the display unit 30 to specify the enlarged range. In addition, about the structure similar to 1st Embodiment, the same number is attached | subjected also in 2nd Embodiment, and detailed description is abbreviate | omitted.

  First, the configuration of the spectrum display device according to the second embodiment will be described.

  In the spectrum display device according to the second embodiment, information I22 in the expanded range corresponding to the element is stored in the storage unit 32 (or information storage medium 34). The display unit 30 displays the elements (element names) stored in the storage unit 32. The range information acquisition unit 22 acquires the expanded range information I22 from the storage unit 32 based on the element specified by the operation unit 10 from the elements displayed on the display unit 30.

  FIG. 9 is a list of elements displayed on the display unit 30. As shown in FIG. 9, the elements are displayed according to a periodic rate table. The storage unit 32 stores enlarged range information I22 corresponding to each element displayed on the display unit 30. The expanded range information I22 includes, for example, energy range information including an energy range in which a peak corresponding to each element appears and an energy range in the vicinity thereof in the energy range of the waveform spectrum obtained by fluorescent X-ray analysis. Further, the expansion range information I22 may include information on the expansion ratio of the expansion range and the reduction ratio of the energy range different from the expansion range.

  The range information acquisition unit 22 receives operation information from the interface unit 21 and determines whether the operation information specifies an element. Then, when the range information acquisition unit 22 determines that the operation information is for specifying an element, the range information acquisition unit 22 acquires, from the storage unit 32, the expanded range information I22 corresponding to the specified element based on the operation information. .

  Next, the operation of the spectrum display device according to the second embodiment will be described.

  First, the processing unit 20 displays the element name on the display unit 30 as shown in FIG. The processing unit 20 may further cause the display unit 30 to display a spectrum to be processed.

  FIG. 10 shows the spectrum S <b> 1 to be processed displayed on the display unit 30.

  Here, the user selects an element from the element name displayed on the display unit 30 by operating the operation unit 10. For example, when the user selects the element Sn in the periodic table shown in FIG. 9, the range information acquisition unit 22 receives this operation information from the interface unit 21 and determines whether the operation information specifies an element. . When the range information acquisition unit 22 determines that the operation information specifies an element, the range information acquisition unit 22 acquires, from the storage unit 32, the expanded range information I22 corresponding to the specified element Sn based on the operation information.

  FIG. 11 is a diagram for explaining processing according to the present embodiment.

  The extended range information I22 includes information on energy ranges (enlarged ranges) I1 and I2 including the energy range in which the peak of the element Sn appears and the energy range in the vicinity thereof as shown in FIG. The enlargement range information I22 includes, for example, information on the enlargement rate of the enlargement range and the reduction rate of the energy range different from the enlargement range. The expansion ratio of the expansion range is set so that, for example, the spectrum included in the expansion range is 75% of the display area of the entire spectrum. Further, the reduction ratio of the range different from the enlarged range is set so that, for example, the spectrum included in the range different from the enlarged range is 25% of the display area of the entire spectrum. Note that information on the enlargement rate and reduction rate may be stored in the spectrum generation unit 24 in advance.

  In the example of FIG. 11, since there are two expansion ranges I1 and I2, the spectrum included in the two expansion ranges I1 and I2 is expanded along the energy axis so as to be 75% of the display area of the entire spectrum. . Specifically, the ratio between the expansion range I1 and the expansion range I2 is 1: 3. Therefore, the spectrum included in the expansion range I1 is expanded along the energy axis so as to be 18.75% of the display area of the entire spectrum. Further, the spectrum included in the expansion range I2 is expanded along the energy axis so as to be 56.25% of the display area of the entire spectrum. Further, the spectrum included in the other ranges I3, I4, and I5 is reduced along the energy axis so as to be 25% of the display area of the entire spectrum. In this way, the spectrum generation unit 24 generates the expanded spectrum S2 shown in FIG.

  According to the present embodiment, the user can easily specify the expansion range.

3. Third Embodiment Next, a spectrum display device according to a third embodiment will be described. In addition, about the structure similar to 1st Embodiment and 2nd Embodiment, the same number is attached | subjected also in 3rd Embodiment, and detailed description is abbreviate | omitted.

  First, the configuration of the spectrum display device according to the third embodiment will be described.

  The processing unit 20 performs processing for displaying a cursor for changing the enlargement range on the display unit 30. Thereby, the display part 30 displays the cursor for changing the expansion range. The user can operate the cursor via the operation unit 10.

  The range information acquisition unit 22 acquires enlarged range information I22 based on the position of the cursor operated by the operation unit 10. The spectrum generation unit 24 generates an expanded spectrum with the expanded range changed based on the expanded range information I22.

  The operation of the spectrum display device according to this embodiment will be described.

  FIG. 12 is a diagram illustrating an example of a spectrum of fluorescent X-rays displayed on the display unit 30.

  As shown in FIG. 12, the user designates an arbitrary energy range (enlarged range) Da of the spectrum displayed on the display unit 30. For example, as shown in FIG. 12, the user may specify the expansion range Da by surrounding a region on the spectrum.

  Further, the user may specify the enlarged range Da using the touch panel 16. For example, the user may select two points on the spectrum by touching two points on the touch panel 16 with a fingertip or the like, and may select the enlarged range Da. When the user moves the fingertip while touching it on the touch panel 16, the enlargement ratio of the enlargement range may be set according to the moving distance along the energy axis of the fingertip.

  FIG. 13 is an enlarged spectrum generated by the spectrum display device 100 according to the present embodiment.

  As shown in FIG. 13, the spectrum display device 100 expands the expanded range Da along the energy axis based on the information on the expanded range Da, and creates an energy range (energy range other than the expanded range) different from the expanded range.
