Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an ultrasonic diagnostic apparatus, particularly a card reading apparatus, for performing ultrasonic diagnosis by transmitting ultrasonic waves into a subject and processing the obtained echo signals. The present invention relates to a provided ultrasonic diagnostic apparatus.

[Prior Art] In an ultrasonic diagnostic apparatus, the depth from the surface, the type of image to be obtained, the gain adjustment value, and the like are different for each subject. For this reason, these data are entered in a medical record or the like, and the knob of the diagnostic device or the like is adjusted in accordance with these data at the time of diagnosis. The conditions to be adjusted include, for example, the following.

In the B-mode ultrasonic diagnosis for obtaining a two-dimensional tomographic image, the echo reception gain is adjusted, the rejection is selectively adjusted to extract only echoes having a certain value or more, and the gain is adjusted according to the depth of the detection position STC ( sensitivity timecontr
ol) adjustment, contrast adjustment, etc.

In the M-mode ultrasonic diagnosis, which displays the change of the reflected echo in the direction of distance as a curve, it is necessary to clearly extract the contour.
Adjustments in FTC (fast time constant) processing.

Adjustment of pulse repetition frequency (PRF) and detection depth (DEPTH) etc. in D mode by pulse Doppler method.

Conventionally, diagnosis is performed after adjusting each subject under such conditions.

[Problems to be Solved by the Invention] In the conventional apparatus, the diagnosis can be performed only after adjusting the condition for each subject by the knob. Therefore, there are problems that the operation is very complicated, it takes a long time to start the diagnosis, and if the adjustment is erroneous, it is necessary to readjust it while checking the result.

[Means for Solving Problems] In the ultrasonic diagnostic apparatus of the present invention, a card in which setting conditions of the diagnostic apparatus necessary for performing diagnosis are previously recorded is inserted and the data recorded therein is read. It has a reader and a controller that automatically sets the conditions of the device according to this data.

[Operation] When performing diagnosis with the ultrasonic diagnostic apparatus of the present invention, first, the card is inserted into the reading apparatus of the ultrasonic diagnostic apparatus. The reader reads the data recorded on the card and sends it to the controller. The control device automatically sets various setting conditions of the ultrasonic diagnostic device based on this data. For this reason, it is not necessary for a person who makes a diagnosis to read the setting conditions from the description of the medical record and adjust the knobs, etc., and the operation is simple, the start time is short, and accurate diagnosis can be performed.

[Example] The IC card 10 is a subject (patient) like a normal diagnostic card.
In addition to the name and the like, data on how to adjust the ultrasonic diagnostic apparatus when performing diagnosis with the ultrasonic diagnostic apparatus is recorded. For example, performing B-mode diagnosis,
Gain value, rejection value, STC adjustment value, contrast, etc. are recorded. The card reader 12, which is a reading device, reads the data recorded therein when the IC card 10 is inserted. The device control unit 14, which is a control device, receives the data read by the card reader 12 and processes the data to supply a control signal to the device circuit unit 16. The device circuit section is set to each value by this signal, and the diagnosis by the diagnosis device 18 is performed.

Here, the keyboard 20 is for inputting a response to a setting value displayed on the CRT 22 as necessary.

The card reader 12 also has a function of writing data to the IC card 10 in response to a signal from the device control unit 14.

Next, the operation of this ultrasonic diagnostic apparatus will be described.

When a subject (patient) is diagnosed by the ultrasonic diagnostic apparatus, first, the IC card 10 for the subject is inserted into the card reader 12 of the diagnostic apparatus 18. Then, the card reader 12 reads the data recorded in the IC card 10. The read data is sent to the device control unit 14 where it is processed and used as an operation signal for setting each set value.
Then, various set values of the device circuit section 16 are set by this signal. Then, the diagnostic device 18 diagnoses the subject.

Here, a part of the contents of the IC card 10 is first displayed on the CRT 22. That is, it includes general items such as the subject (patient) name, date of birth, sex, disease name, medical history, medical history, and a list of set values of the apparatus at the time of previous (and previous) ultrasonic diagnosis. Then, if the set value is the same as the previous set value, the fact is input from the keyboard 20 and a signal is output from the device control unit 14. And if you want to change the setting value, enter a new setting value from the keyboard 20, or
Or, operate the knob directly to change the set value.

When the diagnosis is completed, the set value at that time is written in the IC card 10 by the card reader 12 together with the date of diagnosis. This makes this data available for the next diagnosis.

It should be noted that, in the above-mentioned embodiment, only the IC card is adopted as the card, but the present invention is not limited to this, and a card having a bar code, a punch card, a magnetic card, an optical card or the like may be adopted.

[Effects of the Invention] As described above, according to the ultrasonic diagnostic apparatus of the present invention, data necessary for ultrasonic diagnosis of a subject is recorded in the card, so that the card is recorded in the apparatus at the time of diagnosis. Just insert the device and the device will be adjusted automatically for quick and accurate diagnosis.
