Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, are intended to fall within the scope of the present invention.
Referring to fig. 1, fig. 1 is a flow chart of an embodiment of a method for controlling low power consumption of an ultrasonic diagnostic apparatus according to the present invention, including:
in step 11, echo data features are scanned and extracted.
In the embodiment of the invention, the ultrasonic diagnostic equipment is in a reset setting state after being started, and detection related parameters are required to be set. The parameters related to detection comprise a transmitting channel setting, a receiving channel setting, a frequency of detection operation and a detection signal characteristic which are required to be used in detection. After the setting is completed, the ultrasonic diagnostic apparatus jumps to an idle waiting state. In the idle waiting state, the ultrasonic diagnostic equipment does not perform detection operation; when a scan start instruction is received, the ultrasonic diagnostic apparatus enters a normal scan state. In a normal scanning state, the ultrasonic diagnostic apparatus calculates scanning information according to current working conditions such as depth, frequency, imaging mode and the like, and sets a current transmitting and receiving channel according to the scanning information.
The scanning of the ultrasonic diagnosis equipment is divided into three stages, namely a parameter preparation stage, a transmitting stage and a receiving stage by taking a transmitting line as a unit.
Specifically, referring to fig. 2, fig. 2 is a flow chart of three phases of normal scanning performed by the ultrasonic diagnostic apparatus of the present invention, including:
in step 211, the transmit and receive related parameter settings are prepared.
The parameter preparation stage is used for preparing related parameter settings for transmitting and receiving; the parameters used for transmitting and correlating comprise the number of transmitting lines, transmitting positions, transmitting voltages, transmitting delays, transmitting apertures, transmitting waveforms and transmitting focuses, and the parameters used for receiving and correlating comprise receiving delays, receiving apertures and receiving focuses.
In step 212, the transmit channel sets the transmit chip to transmit.
Specifically, each transmitting channel sets a transmitting chip to transmit according to parameters such as the transmitting delay, the transmitting aperture, the transmitting waveform and the like calculated in the parameter preparation stage.
In step 213, the chip of the receive channel receives the echo to complete the beam forming.
Wherein the transmitting line is operated according to a set pulse repetition time, and each period comprises the three phases.
Further, after the ultrasonic diagnostic equipment enters a working detection state, carrying out detection-related transmitting and receiving control according to the set detection parameters, selecting echo data of a receiving channel, and extracting echo data characteristics.
In step 12, it is determined whether the ultrasonic diagnostic apparatus is in an invalid scanning stage based on the echo data characteristics.
Wherein, the characteristics of the echo signals are different when the ultrasonic diagnostic equipment is contacted or not contacted with the human body. The reflection of the ultrasonic wave is related to the acoustic impedances at the two sides of the interface, and the larger the difference of the acoustic impedances of the two media is, the stronger the reflection of the incident ultrasonic beam is; the smaller the acoustic impedance, the weaker the reflection.
Specifically, referring to fig. 3, fig. 3 is a schematic diagram showing characteristics of echo signals of the ultrasonic diagnostic apparatus according to the present invention under different conditions.
In a specific implementation scenario, for example, when the ultrasonic diagnostic apparatus is not covered with the couplant, because the acoustic impedance of the ultrasonic diagnostic apparatus is greatly different from that of air, the ultrasonic waves emitted by the ultrasonic diagnostic apparatus enter the air to generate a strong reflection effect, and reflection is formed on the surface of the ultrasonic diagnostic apparatus, so that most of emitted signals vibrate back and forth in the ultrasonic diagnostic apparatus, and a significant dead wave layer is displayed on an image.
In another specific implementation scenario, when the ultrasound diagnostic apparatus covers the couplant but does not contact the human body, most of the emitted energy is emitted into the air through the couplant because the acoustic impedance of the couplant is close to that of the ultrasound diagnostic apparatus, and the surface of the couplant is irregular, so that a regular dead wave layer is difficult to appear on the image. The amplitude of the received echo signal is rapidly attenuated along with the increase of time, and the amplitude is kept unchanged after a certain time is reached, so that the amplitude is consistent with the noise level of the system.
Specifically, the ineffective scanning stage is when the ultrasonic diagnostic apparatus is not in contact with the human body. During the use of the ultrasonic diagnostic apparatus, when a doctor scans and diagnoses a patient, the doctor may need to switch probes or switch examination modes, or may interrupt scanning in a short time due to some transactional problems, and in these operation gaps, the ultrasonic diagnostic apparatus is in an ineffective scanning stage because it is not in contact with the human body.
In another specific implementation scenario, when the ultrasonic diagnostic apparatus contacts the human body through the couplant, the acoustic impedance of the couplant is similar to that of the human body, so that reflection loss can be reduced, most of ultrasonic emission energy enters the human body, emission is formed in different tissue structures of the human body, and the echo signal at the moment has a characteristic of increasing attenuation along with time although the attenuation coefficient of the couplant is smaller, but the amplitude of the echo signal is relatively higher, and the signal can be attenuated to be similar to the noise level only when the time reaches a certain length.
In step 13, when the determination result is yes, the ultrasonic diagnostic apparatus enters a low power consumption detection state.
In a specific implementation scenario, after the ultrasonic diagnostic equipment enters a working detection state, the transmitting and receiving channels are scanned according to a scanning mode commonly used by the ultrasonic diagnostic equipment to transmit and receive, and data of one or more channels are selected from the channels currently in the transmitting working state to perform signal characteristic detection and judgment. When the ultrasonic diagnosis equipment is not contacted with the human body as a judgment result, the ultrasonic diagnosis equipment jumps to a low-power consumption detection state. In the low power consumption detection state, only the transmitting and receiving channels related to detection are kept in the working state, and the rest transmitting and receiving channels enter the low power consumption state.
In another specific implementation scenario, after the ultrasonic diagnostic equipment enters a working detection state, the transmitting and receiving channels are scanned according to a scanning mode commonly used by the ultrasonic diagnostic equipment to transmit and receive, and data of one or more channels are selected from the channels currently in the transmitting working state to perform signal characteristic detection and judgment. When the ultrasonic probe is not contacted with the human body as a judging result, the ultrasonic diagnostic equipment stops conventional scanning, restarts scanning at set time intervals, and judges whether the ultrasonic diagnostic equipment is contacted with the human body according to the extracted echo data characteristics. When the judgment result is that the ultrasonic diagnosis equipment is not in contact with the human body, continuing to start scanning at set time intervals and extracting echo data characteristics for detection; when the ultrasonic diagnostic apparatus is in contact with the human body as a result of the judgment, the routine scanning is started. Wherein the set time interval is 1s; wherein, in the time interval that sets for, all transmitting channels and receiving channels stop working.
Compared with the prior art, the method for controlling the low power consumption of the ultrasonic diagnostic equipment is characterized in that the ultrasonic diagnostic equipment stops conventional scanning in an invalid scanning stage and performs scanning and detection again at a set time interval, so that the ultrasonic diagnostic equipment can enter a working detection state in time, and meanwhile, because all transmitting channels and receiving channels stop working in the set time interval, the ultrasonic diagnostic equipment can be maintained in the low power consumption detection state, and the power consumption of the ultrasonic equipment is further reduced.
Further, the low power state includes a low power mode or a power-down mode supported by the chip when the corresponding channel on the transmitting and receiving chip enters, and may also include cutting off the power supply of the chip or cutting off the working clock input of the chip.
And under the low power consumption state, selecting echo data of the appointed receiving channel, extracting the characteristics of the echo data, and comparing and judging with the set signal characteristics. And when the ultrasonic diagnosis equipment is not contacted with the human body as a judgment result, the ultrasonic diagnosis equipment is kept to work in a low-power-consumption working state.
Specifically, channels corresponding to leftmost, middle and rightmost array elements of the ultrasonic diagnostic equipment can be selected for transmitting and receiving according to a set time period, the set time interval can be set to be longer than the time interval of normal scanning, for example, 10ms intervals, the transmission can be set to be pulse transmission, and the transmission pulse can be set to be 2 periods. And the ultrasonic diagnostic equipment maintains a low-power consumption detection state when the echo data characteristics of the three channels are indicated to be not in contact with the human body.
In yet another specific implementation scenario, if the ultrasonic diagnostic apparatus receives an indication signal that the system is entering an operational low power consumption state in the operational detection state, the ultrasonic diagnostic apparatus also jumps to the low power consumption detection state.
The running low-power consumption state refers to that the system is in a scanning state in real time, when the system is in a scanning state, some low-power consumption measures are designed based on the low-power consumption design consideration, such as on-line or frame-to-frame, some empty scanning exists, and in the empty scanning state, a transmitting channel or a receiving channel is in a partial working state or a non-working state to realize the running low-power consumption. The operation of the line-to-line system has low power consumption, and is commonly in a one-dimensional scanning mode, including M mode and pulse Doppler PW. When one-dimensional scanning mode is performed, there is a condition of low power consumption running from line to line when the PRT design is low. Frame-to-frame operation is low in power consumption, and when the scanning frame rate is not required to be high under certain conditions of shallow depth, some empty scans can be inserted between scanning frames to reduce the operation power consumption.
Wherein, under the working detection state, the ultrasonic diagnostic equipment jumps to the idle waiting state if receiving a scanning stop instruction.
Wherein, under the low power consumption detection state, the ultrasonic diagnostic equipment jumps to an idle waiting state if a scanning stop instruction is received.
In yet another specific implementation scenario, the ultrasonic diagnostic apparatus jumps to a working detection state in a low power consumption detection state if it is detected that the ultrasonic diagnostic apparatus is in contact with a human body.
Further, the ultrasonic diagnostic apparatus is already in the operation detection state, and if it is detected that the ultrasonic diagnostic apparatus is still in contact with the human body, the current operation state of the ultrasonic diagnostic apparatus is maintained.
Referring to fig. 4, fig. 4 is a schematic structural diagram of an ultrasonic diagnostic apparatus of the present invention, which includes a control center 401, a scan control module 402, a transmitting module 403, a transmitting channel 404, an ultrasonic probe 405, a receiving channel 406, a receiving module 407, and a detecting module 408.
The control center 401 is coupled to the scan control module 402 and the detection module 408, respectively; wherein, the control center 401 sets the scan control module 402 for ultrasonic scan related parameter setting and the detection module for detecting related parameter setting. Wherein the parameters related to ultrasound scanning include parameters for transmitting and parameters for receiving. The parameters used for transmitting and correlating comprise the number of transmitting lines, transmitting positions, transmitting voltages, transmitting delays, transmitting apertures, transmitting waveforms and transmitting focuses, and the parameters used for receiving and correlating comprise receiving delays, receiving apertures and receiving focuses. The parameters used for detecting the correlation include the setting of the transmitting channel, the setting of the receiving channel, the frequency of the detecting operation and the characteristic of the detected signal which are needed to be used in the detection.
The scan control module 402 is configured to generate regular emission-reception control, and complete emission of all scan lines required for imaging by the ultrasonic diagnostic apparatus; the scan control module 402 is electrically connected to the transmitting module 403, and is further configured to generate a transmission start signal required by the transmitting module.
The transmitting module 403 is in signal connection with one or more transmitting channels 404, and generates delay and transmitting waveforms of focusing required by each transmitting channel 404 according to the transmitting parameters of the current scanning line, so as to determine whether each transmitting channel 404 starts transmitting under the current scanning line.
The ultrasound probe 405 is coupled to the transmit channel 404 and the receive channel 406, respectively.
The emission channel 404 generates a corresponding emission waveform according to the setting of the emission channel, so as to achieve the effect of emission focusing.
The ultrasonic probe 405 converts the electrical signal transmitted from the transmission channel 404 into acoustic vibrations for scanning a human body or other objects, and simultaneously converts acoustic vibrations caused by echoes into received electrical signals.
The echo electrical signal is amplified and filtered by the receiving channel 406 and then converted into an echo digital signal by an analog-to-digital converter.
The receiving module 407 is in signal connection with the receiving channel 406 and is used for receiving the echo digital signal and carrying out beam synthesis operation according to the set parameters to obtain echo line data of ultrasonic imaging; further, the receiving module transmits the received digital signal of the designated channel echo to the detecting module 408 for detection.
The detection module 408 is in signal connection with the receiving module 407, and is configured to perform detection operation on the echo digital signal, and compare the extracted feature with the set detection signal feature to obtain an indication signal indicating whether the ultrasonic probe is in contact with the human body.
Wherein, the characteristics of the echo signals are different when the ultrasonic diagnostic equipment is contacted or not contacted with the human body. The reflection of the ultrasonic wave is related to the acoustic impedances at the two sides of the interface, and the larger the difference of the acoustic impedances of the two media is, the stronger the reflection of the incident ultrasonic beam is; the smaller the acoustic impedance, the weaker the reflection.
In a specific implementation scenario, for example, when the ultrasonic diagnostic apparatus is not covered with the couplant, because the acoustic impedance of the ultrasonic diagnostic apparatus is greatly different from that of air, the ultrasonic waves emitted by the ultrasonic diagnostic apparatus enter the air to generate a strong reflection effect, and reflection is formed on the surface of the ultrasonic diagnostic apparatus, so that most of emitted signals vibrate back and forth in the ultrasonic diagnostic apparatus, and a significant dead wave layer is displayed on an image.
In another specific implementation scenario, when the ultrasound diagnostic apparatus covers the couplant but does not contact the human body, most of the emitted energy is emitted into the air through the couplant because the acoustic impedance of the couplant is close to that of the ultrasound diagnostic apparatus, and the surface of the couplant is irregular, so that a regular dead wave layer is difficult to appear on the image. The amplitude of the received echo signal is rapidly attenuated along with the increase of time, and the amplitude is kept unchanged after a certain time is reached, so that the amplitude is consistent with the noise level of the system.
In another specific implementation scenario, when the ultrasonic diagnostic apparatus contacts the human body through the couplant, the acoustic impedance of the couplant is similar to that of the human body, so that reflection loss can be reduced, most of ultrasonic emission energy enters the human body, emission is formed in different tissue structures of the human body, and the echo signal at the moment has a characteristic of increasing attenuation along with time although the attenuation coefficient of the couplant is smaller, but the amplitude of the echo signal is relatively higher, and the signal can be attenuated to be similar to the noise level only when the time reaches a certain length.
Referring to fig. 5, fig. 5 is a state diagram of an embodiment of a method for controlling low power consumption of an ultrasonic diagnostic apparatus according to the present invention.
Specifically, after the ultrasonic diagnostic apparatus is started, the detection module 408 is in the reset setting state 500, and waits for the control center 401 to set the scan control module 402 for ultrasonic scan related parameter settings and the detection module 408 to detect the related parameter settings. Wherein the parameters related to ultrasound scanning include parameters for transmitting and parameters for receiving. The parameters used for transmitting and correlating comprise the number of transmitting lines, transmitting positions, transmitting voltages, transmitting delays, transmitting apertures, transmitting waveforms and transmitting focuses, and the parameters used for receiving and correlating comprise receiving delays, receiving apertures and receiving focuses. The parameters used for detecting the correlation include the setting of the transmitting channel, the setting of the receiving channel, the frequency of the detecting operation and the characteristic of the detected signal which are needed to be used in the detection.
In the idle waiting state 501, the detection module 408 is in the idle state and does not perform detection operation, when the detection module 408 receives a scan start instruction, the operation detection state 502 is skipped, otherwise the operation detection state 501 is kept.
In a specific implementation scenario, after the scanning is started, the detection module 408 enters the working detection state 502, and performs detection-related transmission and reception control according to the set detection conditions. Echo data of the designated receiving channel 406 is selected, the echo data characteristics are extracted, and comparison and judgment are performed with the set signal characteristics. When the ultrasonic probe 405 is in contact with the human body as a result of the judgment, the current working state of the ultrasonic diagnostic apparatus is maintained, while the detection module 408 is maintained in the working detection state 502; when the ultrasonic probe 405 is not in contact with the human body as a result of the judgment, the state is jumped to the low power consumption detection state 503. The detection module 408, in the operation detection state 502, jumps to the idle waiting state 501 if a scan stop instruction is received.
In another specific implementation scenario, after the scanning is started, the detection module 408 enters the working detection state 502, and performs detection-related transmission and reception control according to the set detection conditions. Echo data of the designated receiving channel 406 is selected, the echo data characteristics are extracted, and comparison and judgment are performed with the set signal characteristics. When the ultrasonic probe 405 is in contact with the human body as a result of the judgment, the current working state of the ultrasonic diagnostic apparatus is maintained, while the detection module 408 is maintained in the working detection state 502; when the ultrasonic probe 405 is not in contact with the human body as a result of the judgment, the scanning control module 402 jumps to the idle waiting state 501 and jumps back to the working detection state 502 at set time intervals, and the detection module 408 judges whether the ultrasonic probe 405 is in contact with the human body according to the extracted echo data characteristics. When the ultrasonic probe 405 is not in contact with the human body as a result of the judgment, the scanning control module 402 continues to jump to the working detection state 502 at set time intervals, and the detection module 408 extracts echo data characteristics for detection; when the ultrasonic probe 405 is in contact with the human body as a result of the determination, the scan control module 402 jumps to the work detection state 502. Wherein the set time interval is 1s; wherein, in the time interval that sets for, all transmitting channels and receiving channels stop working.
In the operational detection state 502, if the detection module 408 receives an indication that the system is entering the run low power state, then the low power detection state 503 will also be skipped.
Further, in the low power consumption detection state 503, only the transmitting and receiving channels related to detection are kept in the working state, and the rest transmitting and receiving channels enter the low power consumption state. In this state, echo data of the designated receiving channel 406 is selected, and the echo data feature is extracted and compared with the set signal feature. When the ultrasonic probe 405 is not in contact with the human body as a result of the judgment, the ultrasonic diagnostic apparatus is kept operating in the low power consumption operating state while the detection module 408 is kept in the low power consumption detection state 503.
Specifically, channels corresponding to leftmost, middle and rightmost array elements of the ultrasonic probe 405 may be selected to transmit and receive according to a set time period, where the set time interval may be set to be longer than a time interval of normal scanning, for example, a 10ms interval, the transmission may be set to be pulse transmission, and the transmission pulse may be set to be 2 periods.
