Description
Technical Field
The invention relates to the field of medical instruments, in particular to an ultrasonic diagnostic device and a method for reducing ultrasonic echo data interference.
Background
The ultrasonic-magnetic navigation mode is to display the position information of the puncture needle in the human body on an ultrasonic image when a puncture operation is performed on internal tissues and organs of the human body by using the puncture, so that the movement of the puncture needle in the tissues and organs in the human body is guided by the ultrasonic image.
The doctor needs to observe the position of the puncture needle in human tissue in real time, so the position information of the puncture needle and the echo data of the ultrasonic image need to be transmitted to a host computer from a probe to be displayed simultaneously, and the data cannot be interrupted.
As shown in fig. 1, the transmission of the position information of the puncture needle and the echo data of the ultrasound image is that the host sends a command for reading data, then the data enters from the sound head 1 of the probe, passes through the cable 2 between the sound head 1 and the plug 3 to reach the plug 3, then passes through the socket to reach the probe board 4, and finally is transmitted to the host. Therefore, the transmission is highly coupled in space on the physical line, especially at the position of the probe plug 3, the pinout for transmitting echo data and the pinout for transmitting the reading puncture needle position information and the returned position information data are arranged on the same board card, and the spatial positions are very close. The command for reading the position data of the puncture needle and the data return are transmitted through a spi line between the host and the probe plug 3, so that the spi transmission line interferes with ultrasonic echo data, the ultrasonic image effect is deteriorated, and the puncture needle is influenced to be positioned.

The processor 220 is configured to excite the ultrasound probe 110 to transmit an ultrasonic wave to the target tissue a through the transmission/reception control circuit 120, control the ultrasound probe 110 to receive an ultrasonic echo of the ultrasonic wave returned from the target tissue a through the transmission/reception control circuit 120 and generate multiline echo data, and control the ultrasound probe 110 to transmit the multiline echo data, where, as shown in fig. 3, transmission between each line of echo data has a time interval; transmitting a part of first information in the time interval of echo data transmission, so that the first information and the multi-line echo data are transmitted in a time-sharing manner; generating an ultrasonic image according to the multi-line echo data; and obtaining complete first information according to the first information of each part in a plurality of time intervals of the multiline echo data transmission. Because the first information is transmitted in the time interval of the transmission of the echo data, the interference on the echo data is avoided, the interference source of the echo data is reduced, and the quality of the ultrasonic image is improved.
Wherein the first information includes: at least one of puncture needle position information, probe ID, probe serial number, electronic tag, key code and probe sensitivity. The first information is the puncture needle position information, and the following description will be made by way of specific examples. In the specific embodiment shown in fig. 4, the ultrasonic diagnostic apparatus includes an ultrasonic probe 110 and a host computer. Wherein the ultrasound probe 110 comprises a sound head 111, a cable 112 and a probe plug 113. The host includes a housing (not shown), a probe card 210 mounted on the housing, and a processor 220.
The acoustic head 111 is a main functional component of the ultrasound probe 110, and is configured to transmit an ultrasound wave to the target tissue a, receive an ultrasound echo of the ultrasound wave returned from the target tissue a, and generate multiline echo data, and the echo data is transmitted to the host through the cable 112 and the probe plug 113. The acoustic head 111 is also used for receiving puncture needle position information, and the puncture needle position information is also transmitted to the host computer through the cable 112 and the probe plug 113.
The probe plug 113 is plugged on the probe board 210 of the host machine to realize the electrical connection between the ultrasonic probe 110 and the host machine.
The probe board 210 is provided with one or more interfaces that are adapted with the probe plug 113 to receive data output by the ultrasound probe 110. In this embodiment, the probe board 210 is provided with a plurality of interfaces adapted to the probe plugs 113, so that the ultrasonic diagnostic apparatus can connect a plurality of ultrasonic probes 110.
The function of the processor 220 is specifically described by using the method shown in fig. 5, that is, the processor 220 may also implement the method for reducing the interference of the ultrasonic echo data provided by the embodiment of the present invention, including the following steps:
step 1, the processor 220 activates the ultrasound probe 110 to transmit ultrasound waves to the target tissue through the transmission/reception control circuit 120.
For example, the processor 220 sets a scanning time sequence according to the current working mode before the ultrasonic scanning, and ensures that the time interval of each line of echo data meets the requirement of the transmission time of the puncture needle position information, so as to realize time-sharing transmission. Specifically, the transmission/reception control circuit 120 excites the ultrasonic probe 110 to periodically transmit ultrasonic waves to the target tissue, wherein one transmission period transmits an ultrasonic beam, and the ultrasonic beam generates a line echo data through the echo reflected by the target tissue. By periodically transmitting the ultrasound beam, the ultrasound echoes are periodically received, and each line of echo data generated and transmitted to the processor 220 is also periodic. The ultrasound probe 110 performs preparation work before transmitting an ultrasound beam, such as acquiring a scan timing, in a time period of a transmission cycle. The ultrasonic probe 110 transmits one ultrasonic beam to the target tissue in accordance with the scan timing in another period, and receives and transmits one line of echo data in accordance with the scan timing in a second period t2, so that each line of echo data is transmitted in the above-described transmission cycle. And a part of the first information is transmitted in the first time period t1, which can be realized by reading the first information in the ultrasound probe 110 in a certain time period, for example, in the time period with the same duration as t 1. The echo data is analog signals, and the first information is digital signals, that is, the echo data and the first information are transmitted to the processor 220 through the cable 112, but they are transmitted through different wires. The invention solves the problem that echo data is easy to interfere by a software mode, namely an echo data and first information time-sharing transmission mode without changing the hardware structure of the existing ultrasonic diagnostic equipment, can be compatible with the existing ultrasonic diagnostic equipment and has wide application range.
For example, the ultrasound image is generated according to the multiline echo data obtained in the first number M of transmission cycles, that is, the ultrasound image can be generated according to the M-line echo data, the first number M is an integer greater than or equal to 2, taking the size of one frame of ultrasound image as a × B, A as the image width, B as the height, and the height direction as the depth direction of the target tissue as an example, one line of echo data corresponds to an image with the size of (a/M) × B in one frame of ultrasound image, so that the size of the ultrasound image is determined, and the size of M can be determined by combining the number of transmitting array elements and the like.
And 5, the processor 220 obtains complete first information according to each part of the first information in a plurality of time intervals of the multi-line echo data transmission. For example, according to each partial first information obtained in a second number N of transmission cycles, complete first information is obtained, that is, N partial first information may obtain complete first information, where the second number N is an integer greater than or equal to 2. The second number N may be set according to the time requirement of the first information, and may be greater than M, less than M, or equal to M. In this embodiment, the first information is puncture needle position information, and the first number M is equal to the second number N in consideration of the real-time positional relationship between the puncture needle position information and the ultrasound image. In this embodiment, the processor 220 also displays the puncture needle image and its location on the ultrasound image displayed on the display 231 based on the complete puncture needle position information. Therefore, the user can observe the position of the puncture needle in the target tissue, and the ultrasonic image of the target tissue has good display effect because the ultrasonic image is not interfered by the position information of the puncture needle.
The first time period t1 cannot be too short, which needs to satisfy the time requirement for the ultrasound probe 110 to acquire the transmission sequence parameters and the reception sequence parameters, and too short results in too long time for obtaining the complete puncture needle orientation information, thereby causing the puncture needle image displayed on the display to be jammed. The first time period t1 should not be too long, which would decrease the frame rate of the ultrasound image and affect the consistency of the ultrasound image display. Therefore, the time interval T1 between two adjacent lines of echo data needs to be reasonably controlled, in this embodiment, the duration of M transmission cycles T (the time for transmitting M lines of echo data required for completing one frame of ultrasound image) is less than or equal to the period (1/f1) corresponding to the minimum allowable frame rate f1 of the ultrasound image, and the duration of N transmission cycles T (the time for transmitting N pieces of the partial puncture needle position information required for completing the complete puncture needle position information) is less than or equal to the period (1/f2) corresponding to the minimum allowable frame rate f2 of the puncture needle image. The ultrasound image minimum allowable frame rate f1 and the puncture needle image minimum allowable frame rate f2 may be frame rates that do not cause a stuck on the display. Specifically, the first time period t1 may be defined by the following formula:
t1is a first time period, t2For the second time period, the time when the continuous transmission of the line echo data is completed can be selected as the second time period, of course t2Slightly longer than the time for completing the continuous transmission of the first line echo data is also possible; t is1conThe time length required for the complete puncture needle position information to be continuously transmitted is knownAmount of the compound (A). T is1maxThe period corresponding to the minimum allowable frame rate of the puncture needle image is also a known quantity, and is 25ms in the embodiment; t is2conThe time duration required for the continuous transmission of the M-line echo data is also a known quantity. T is2maxThe period corresponding to the minimum allowable frame rate for the ultrasound image is also a known quantity. It can be seen that the value of the first time period t1 can be transmitted in a time-sharing manner within the range limited by the formulas (1) and (2) to avoid interference, and the display of the ultrasound image and the puncture needle image is not affected.
As shown in fig. 6, the processor 220 controls a portion of the first information to be transmitted during a first time period T1 of the transmission period T, such that time-sharing the first information with the multiline echo data includes:
And step 33, judging whether the current time is within a first time period t1, if so, executing step 34, otherwise, executing step 33 again.
Of course, in other embodiments, the control unit controls a part of the first information to be transmitted in the first time period T1 of the transmission period T, so that the first information and the multiline echo data are transmitted in a time-sharing manner, which may also be implemented by the probe plug 113 of the ultrasound probe 110, and the specific process is the same as that in fig. 6 and is not described in detail.
In summary, before the ultrasonic image scanning is started, the scanning time sequence is set according to the current working mode, so that the time interval between echo data lines meets the requirement of the transmission time of the puncture needle position information; after entering the puncture magnetic navigation mode, the processor is responsible for transmitting puncture needle position information at regular time. The processor transmits puncture needle position information according to bytes according to whether the transmission of the puncture needle position information data packet is finished currently and whether the puncture needle position information data packet is positioned in a time interval between echo data lines currently; after the transmission of the position information of one pack of puncture needles, the process of transmitting the position information of the next pack of puncture needles is started, and the process is repeated continuously. Therefore, the puncture needle position information and the echo data are transmitted in a time-sharing mode, the display of the puncture needle image and the ultrasonic image is not influenced, and the interference of the puncture needle position information on the echo data is avoided.
