Due to the different interface morphology, the movement of tissues and organs, and the degree of absorption of ultrasound, the echo images have certain commonalities and certain characteristics. Combining physiological and pathological anatomy knowledge with clinical medicine, observe, analyze and summarize these. Different rules, B-ultrasound can clearly display various cross-sectional images of various organs and surrounding organs. Because the image is rich in physical sense and close to the actual structure of the anatomy, the application of ultrasonic testing can confirm the diagnosis early.

It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. example. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In order to facilitate the clear description of the technical solution of the embodiment of the present invention, in the embodiment of the present invention, the "first" is used to represent a specific concept, such as "the first sample management library" refers to "sample management". A particular sample management library in the library, one skilled in the art can understand the "first" and limit the number and execution order.

[0027] Embodiment 1

[0028] An embodiment of the present invention provides an ultrasonic detecting method, which is specifically applied to a main controller of a B-type ultrasonic diagnostic system as an example. First, a brief introduction of the B-mode ultrasound diagnosis system is given as follows:

[0029] As shown in FIG. 1, the B-mode ultrasonic diagnostic system is mainly composed of four parts: a front end, a middle end, a back end, and a main controller. The front end is the transmitting and receiving part of the ultrasonic wave; the middle end is the tissue structure information extracting part; the back end is the imaging processing and display part; the main controller realizes the management and control of the whole system. The front end portion consists of a receive/transmit multiplexer, a transmit circuit, a receive isolation/preamplifier circuit, a Time Gain Control (TGC) amplifier, a beamformer, and a front-end controller. The transmitting circuit is mainly responsible for the emission of the ultrasonic wave, and the transmitting circuit generates a waveform that meets the requirements, and can emit a high-frequency transmitting pulse under the excitation of the transmitting excitation pulse, and the high-voltage transmitting pulse acts on the probe to generate the ultrasonic wave. The sound wave reflected from the human tissue is collected by the probe and converted into an echo signal. The echo signal enters the receiving channel through the receiving/transmitting multiplexer. In order to avoid the high-voltage transmitting pulse from damaging the receiving channel TGC amplifier, the receiving isolation must be inserted before the TGC amplifier. The preamplifier circuit, the role of the TG C amplifier is to compensate for the attenuation of the ultrasonic wave during propagation in the human body, and the beamformer completes the focus. , aperture control and beam signal synthesis. The mid-end portion is an organization structure information extraction portion, that is, an echo video signal forming portion. The signal processed by the front end is a radio frequency signal whose envelope characterizes the structural information of the biological tissue, and thus requires a demodulation circuit to detect the envelope of the signal from the echo radio frequency signal. The back end is an imaging processing and display portion, which is composed of a frame correlation circuit, a digital scan conversion, and a video processor. The video processor implements post-processing of image signals, such as grayscale transform, pseudo color, character graphics synthesizer, and the like. The main controller is the operating platform of the system, which realizes the management and control of the entire system.

[0030] Next, as shown in FIG. 2, the ultrasonic detecting method provided by the embodiment of the present invention includes:

[0031] S201. The main controller acquires an ultrasonic image collected and processed by the probe and a type identifier of the probe.

[0032] Specifically, the brief introduction of the B-type ultrasonic diagnostic system described above shows that after the probe collects the sound wave reflected from the human body tissue, the transducer receives and converts into an echo signal, and enters the receiving channel through the receiving/transmitting multiplexer. And through the receiving isolation/preamplifier circuit, the TGC amplifier, the beamformer to complete the focus, the aperture control and the beam signal synthesis, and then the middle part of the envelope is detected from the echo RF signal, and the image is completed through the back end part. After processing, the processed ultrasonic image can be finally fed back to the main controller, that is, the main controller acquires the ultrasonic image acquired and processed by the probe.

[0033] In the embodiment of the present invention, the main controller further obtains the type identifier of the probe, and the type identifier may be a serial number of the probe, or a name, etc., which is not specifically limited in the embodiment of the present invention.

[0034] wherein the type of the probe may include a common frequency of 3.0-6.0

The embodiment of the present invention does not specifically limit the convex array probe of the MHz, the linear array probe with a frequency of 5.0-12.0 MHz, the phased array probe with a common frequency of 2.0-4.0 MHz, and the like.

[0035] It should be noted that, generally, the width of the probe and the angle of the transmitting beam determine the size of the ultrasonic imaging field of view. The shape of the probe determines the shape of the imaging field of view. The imaging of the convex array probe is usually a fan shape, and the linear array probe is imaged as a rectangle. The phased array probe is imaged as a cone. The fan shape and the cone shape are not suitable for direct image matching. In order to facilitate subsequent image matching, the acquired ultrasound image is cropped into a rectangle. Due to the limitation of the imaging principle of the ultrasonic device, the ultrasonic image signal-to-noise ratio is low and the speckle noise phenomenon is severe. Therefore, the filtering technique is required to denoise the ultrasonic image, which is not specifically limited in the embodiment of the present invention.

[0036] S202. The main controller selects, according to the type identifier of the probe, a first sample management library corresponding to the type identifier of the probe from a pre-stored sample management library.

[0037] Specifically, in the embodiment of the present invention, a sample management library is pre-stored in the main controller, and the sample management library may be The human organ management library including the abdominal organ and the pelvic organ management library, the superficial organ management library, the cardiac management library, and the like, after the main controller acquires the type identification of the probe, may be identified according to the type of the probe. The first sample management library corresponding to the type identifier of the probe is selected from the pre-stored sample management library, and the preset rule includes:

[0038] The convex array probe identifier corresponds to the abdominal organ and the pelvic organ management library, the line array probe identifier corresponds to the superficial organ management library, and the phased array probe corresponds to the cardiac management library.

[0039] It should be noted that, the foregoing is only an example of the correspondence between the type identifiers of the probes and the corresponding first sample management library, and of course, other corresponding relationships may exist. limited.

[0040] wherein the abdominal organ and the pelvic organ management library may include sample images of organs such as liver, spleen, kidney, pancreas, gallbladder, gastrointestinal tract, genitourinary system, and uterus; superficial organs may include breast, arteries , sample images of organs such as the blood flow of the neck; the heart management library may include sample images of organs such as the heart and the brain.

[0041] S203. The main controller matches the ultrasound image with a sample image in the first sample management library.

[0042] Specifically, the main controller may match the ultrasound image with the sample image in the first sample management library by using a feature-based image matching manner. That is, the feature points are extracted from the acquired ultrasound image and the sample image in the first sample management library as a registration primitive by the Harris algorithm, and the feature points are matched by a Hausdorf f distance matching algorithm. Among them, the feature points include a closed area, an edge, a line intersection, a corner, and the like. The Hausdorff distance is defined as the distance between two sets of points, which can tolerate the deviation of the position of the point, as well as the interference of different points and extra points. The Hausdorff distance-based matching method does not emphasize the one-to-one correspondence between points, but focuses on the measure of the overall similarity between points.

[0043] Of course, the main controller may also match the ultrasound image with the sample image in the first sample management library by other means, which is not described herein again.

[0044] S204. If the matching is successful, the main controller sends a first sample image that matches the ultrasound image to the display, and the user determines the condition according to the first sample image.

[0045] Specifically, if the matching is successful, the primary controller sends the first sample image that matches the ultrasound image to the display, so that the user community can determine its own condition according to the first sample image. [0046] Further, as shown in FIG. 3, in the ultrasonic detecting method provided by the embodiment of the present invention, the main controller selects the probe from a pre-stored sample management library according to the type identifier of the probe. After the type identifier identifies the corresponding first sample management library (step S202), before the main controller matches the ultrasound image with the sample image in the first sample management library (step S203), the method further includes:

[0047] S205. The main controller sends an identifier of the organ corresponding to the sample image in the first sample management library to the display.

[0048] S206. The main controller acquires a first organ identifier selected by the user from the organ identifier.

[0049] Thus, the main controller matches the ultrasound image with the sample image in the first sample management library (step S203), specifically:

[0050] S203a. The main controller matches the ultrasound image with a sample image in a sample management library corresponding to the first organ identifier in the first sample management library.

[0051] That is, in the embodiment of the present invention, after the main controller selects the first sample management library corresponding to the type identifier of the probe from the pre-stored sample management library, the ultrasound image is not directly compared with the first The sample images in the sample management library are matched, but the organ identifier corresponding to the sample image in the first sample management library is first sent to the display, and the user selects a specific organ to obtain a corresponding a first organ identifier, which in turn matches the ultrasound image with a sample image in a sample management library corresponding to the first organ identifier in the first sample management library. For example, the first sample management library may be an abdominal organ and a pelvic organ management library, and the sample management library corresponding to the first organ identifier may be a liver sample management library. Obviously, the sample management library corresponding to the first organ identifier is A branch of the first sample management library can improve the speed of matching by reducing the range of the sample image matched with the ultrasound image, thereby improving the efficiency of the ultrasound detection.

[0052] Specifically, the main controller may perform, by using the feature-based image matching manner, the sample image in the sample management library corresponding to the first organ identifier in the first sample management library. Matching, that is, extracting feature points from the acquired ultrasound image and the sample image in the sample management library corresponding to the first organ identifier by the Harris algorithm as a registration primitive, and then matching the feature by a Hausdorff distance matching algorithm Points are matched. Among them, the feature points include a closed area, an edge, a line intersection, a corner, and the like. The Hausdorff distance is defined as the distance between two sets of points, which can tolerate the deviation of the position of the point, as well as the interference of different points and extra points. Matching methods based on Hausdorff distance do not emphasize points and points A one-to-one correspondence between them, focusing on the measure of overall similarity between sets of points.

[0053] Further, as shown in FIG. 4, in the ultrasonic detecting method provided by the embodiment of the present invention, the main controller matches the ultrasonic image with a sample image in the first sample management library ( After step S203), the method further includes:

[0054] S207. If the matching is unsuccessful, the main controller re-matches the ultrasound image with the sample image in the first sample management library until the matching is successful.

[0055] That is, in the embodiment of the present invention, if the matching of the ultrasound image with the sample image in the first sample management library is unsuccessful, the main controller re-matches the two until the matching is successful.

[0056] Of course, if the matching of the ultrasound image with the sample image in the first sample management library is unsuccessful, the main controller may also send a “match failure” indication message to the display, and the display notifies the user that the current matching fails. This embodiment of the present invention does not specifically limit this.

An embodiment of the present invention provides an ultrasonic detecting method, including: a main controller acquires an ultrasonic image collected and processed by a probe, and a type identifier of the probe; the main controller is configured according to the type of the probe, Selecting, in a pre-stored sample management library, a first sample management library corresponding to the type identifier of the probe; the main controller matching the ultrasound image with a sample image in the first sample management library; If the matching is successful, the main controller sends a first sample image that matches the ultrasound image to the display, and the user determines the condition according to the first sample image. According to the ultrasonic detecting method provided by the embodiment of the present invention, the main controller in the embodiment of the present invention not only acquires the ultrasonic image collected and processed by the probe, but also acquires the type identifier of the probe, and uses the pre-stored sample management library according to the type identifier.

On the one hand, during the implementation of the above ultrasonic detecting method, when the user connects the probe to the ultrasonic detecting system, the main controller in the ultrasonic detecting system is independently completed, and the operator does not need to have rich clinical experience, or must be familiar with the sound. Image and normal human tissue and anatomy and pathology, the general population can achieve ultrasound detection, thus expanding the use of ultrasound detection technology; on the other hand, the above detection method, the scope of detection is not limited to the body's single Part of it, but applicable to different parts of the body, you can select different sample management libraries for image matching according to different probe identifications, thus expanding the ultrasonic detection technology.
