Description

Technical Field

[0001] The present invention relates to the technical field of ultrasound data management, and in particular to an ultrasound therapy control system and a control method based on medical imaging data. Background Art

[0002] Medical ultrasound imaging utilizes ultrasound technology for diagnostic imaging in the medical field, often used to examine organ structure, blood flow, and abnormal tissue. With the widespread application of ultrasound technology, ultrasound examinations are being tasked with a wider range of tasks, and the quality of ultrasound images has become a matter of concern.

[0003] When using the same ultrasound equipment, the image quality is affected by the operator's technique. Good technique results in clear images, making diagnosis easier. However, technique must be performed in a specific order; an incomplete scan often leads to missed areas. Due to differences in experience and knowledge among operators, ultrasound technique is difficult to replicate, resulting in varying ultrasound examination efficiency and imaging results, which in turn affects the doctor's judgment of the patient's condition during subsequent diagnosis and treatment. Summary of the Invention

[0004] The object of the present invention is to provide an ultrasound therapy control system and control method based on medical imaging data to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solution: an ultrasound therapy control method based on medical imaging data, the method comprising:

[0006] Step S100: Obtaining complete ultrasound image information of an examination object for a certain ultrasound examination project from an ultrasound image database, establishing a template image of the examination object, and selecting a target detection area from the template image based on the distribution of sampling positions of the ultrasound probe on the template image during the ultrasound examination of the patient;

[0007] Step S200: a patient who undergoes a certain ultrasound examination is set as a target patient, historical ultrasound examination data of the target patient is obtained, common features of ultrasound images of the certain ultrasound examination item are extracted, and the common features are combined into a feature reference image;

[0008] Step S300: collecting state information of the ultrasound probe in the target detection area, forming the state information into a state sequence, and calculating a first evaluation coefficient of various ultrasound probe states by the difference in state holding time;

[0009] Step S400: collecting a current ultrasound image of a target patient undergoing a certain ultrasound examination, removing common features from the current ultrasound image to obtain a target image, and evaluating the clarity evaluation values ​​of the target image under different states of the ultrasound probe;

[0010] Step S500: Acquire the ultrasonic transmission power and holding time of the ultrasonic probe in different states when performing a certain ultrasonic examination project, and use the ratio of the image clarity evaluation value to the input energy as the second evaluation coefficient of the ultrasonic probe state;

[0011] Step S600: Calculate the state parameters of each state of the ultrasound probe based on the first evaluation coefficient and the second evaluation coefficient, select the states of several ultrasound probes as reference states, and push the ultrasound probe states to relevant ultrasound examination operators when the same patient undergoes an ultrasound examination of a certain ultrasound examination item again.

[0012] Furthermore, step S100 includes:

[0013] Step S101: During an ultrasonic examination, the relative position between the ultrasonic probe and the object to be examined is sampled to obtain N0 sampling positions, and the sampling positions obtained in each sampling are mapped to a template image;

[0014] Step S102: Rasterize the template image to obtain m unit management areas, calculate the average sampling density ρ0, where ρ0 = N0 / m; calculate the regional sampling density ρk of the k-th unit management area, where ρk = Nk / Dk, where Nk represents the number of sampling positions in the k-th unit management area, and Dk represents the area of ​​the k-th unit management area;

[0015] Step S103: selecting a unit management area with a regional sampling density greater than the average sampling density as a target management area, marking the target management area from the patient's actual ultrasound image, and combining all target management areas in the same ultrasound image into a target detection area;

[0016] Because different patients have different bodies, the size of the collected ultrasound images also varies. The relative position of the collected ultrasound probe and the object being tested is mapped to a unified template of the object being tested. In the process of further calculating the distribution of the ultrasound probe, the statistical deviation of the distribution caused by the different sizes of the objects being tested or the offset of the acquisition angle during the acquisition is reduced.

[0017] Select unit management areas with a sampling density greater than the average density. Compared with the complete detected object, the ultrasound probe stays in the target management area longer during the ultrasound detection process, and the areas that doctors pay more attention to during the patient's visit are screened out for image analysis.

[0018] Furthermore, step S200 includes:

[0019] Step S201: obtaining the i-th examination record of a certain ultrasound examination item of a target patient, and obtaining n ultrasound images from the i-th examination record;

[0020] Step S202: Extract the common features of n ultrasound images and obtain the feature reference image P ref ;

[0021] The common features extracted from multiple ultrasound images are regions with minimal variation across the multiple ultrasound images. These regions with minimal variation across multiple ultrasound images are the common features of the ultrasound images. After removing the common features from an ultrasound image, the resulting image is a specific image among the ultrasound images.

[0022] If the clarity of all areas in the ultrasound image is evaluated, the clarity of the common feature area may be higher and the clarity of the specific area may be lower, or the common feature area may account for a larger proportion of the ultrasound image and the specific area may account for a smaller proportion of the ultrasound image, resulting in a higher clarity evaluation value of the ultrasound image, but the clarity of the specific area is lower, and the recognizability of the ultrasound image is still not high. Therefore, focusing on the evaluation of the specific part of the ultrasound image can better reflect the impact of the change in clarity of the ultrasound image on whether the content on the image is easy to identify.

[0023] Furthermore, step S300 includes:

[0024] Step S301: a unit time interval is set, and at each unit time interval, the angle between the ultrasonic probe and the horizontal position and the pressure between the ultrasonic probe and the contact surface are collected to obtain an ultrasonic probe status;

[0025] Step S302: Arrange the ultrasound probe states according to the order of acquisition time to obtain a state sequence. Obtain any three consecutive ultrasound probe states in the state sequence and record them as st1, st2, and st3. The time period from the end of st1 to the end of st2 is recorded as the holding time t2 of st2, and the time period from the end of st2 to the end of st3 is recorded as the holding time t3 of st3.

[0026] Step S303: Calculate the relative reference coefficient f32 of st3 relative to st2, where f32 = t3 - t2. Merge the ultrasound probe states with the same state sequence as st3 into ultrasound probe state type 3. Take the average of the reference coefficients of all ultrasound probe states in type 3 relative to the previous ultrasound probe state to obtain the first evaluation coefficient α of the ultrasound probe state in type 3.

[0027] The first evaluation coefficient evaluates the relative preference of different ultrasound probe states. In a period of continuously changing ultrasound probe states, the first evaluation coefficient of the ultrasound probe state with a relatively long maintenance time will become larger; the first evaluation coefficient compares the relationship between the relative maintenance time of different ultrasound states, reduces the influence of factors other than ultrasound detection during the diagnosis and treatment process, and makes the screened ultrasound probe state more in line with the actual situation during the ultrasound examination process.

[0028] Furthermore, step S400 includes:

[0029] Step S401: Obtain an ultrasonic image Px of the ultrasonic probe in a certain ultrasonic probe state stx, remove the common features in Pref from Px, and obtain the target image P corresponding to stx tar x ;

[0030] Step S402: The target image P tar x Converted into a grayscale image, by calculating the target image P tar x The change gradient of the pixel gray value in the corresponding gray image is used to obtain the target image P tar x The clarity evaluation value G tar x .

[0031] Furthermore, step S500 includes:

[0032] Step S501: when a target patient is currently undergoing a certain ultrasound examination, the ultrasound transmission power Wx of the ultrasound probe state stx and the holding time tx of stx are obtained, and the ultrasound input energy Jx is calculated, where Jx=Wx·tx;

[0033] Step S502: Calculate the second evaluation coefficient βx of the ultrasonic probe state stx, βx=G tar x / Jx;

[0034] The second evaluation coefficient reflects the contribution of ultrasonic energy to improving the clarity of ultrasonic images. In actual applications, the ultrasonic examination operator's operating techniques may affect the recognizability of the obtained ultrasonic images under the same ultrasonic transmission power. In addition, during the ultrasonic examination process, excessive ultrasonic transmission energy will not only produce virtual images in the ultrasonic image and affect the recognition degree of the ultrasonic image, but excessive ultrasonic power may also cause thermal damage to the tissue, especially in the case of long-term contact, which may cause pain or other adverse reactions. The ultrasonic probe status is optimized based on the contribution of ultrasonic transmission power to the clarity of the ultrasonic image.

[0035] Furthermore, step S600 includes:

[0036] Step S601: Calculate the state parameter ηx of the ultrasonic probe state stx, ηx=αx·βx, where αx represents the first evaluation coefficient corresponding to the ultrasonic probe state stx;

[0037] Step S602: summing the state parameters of the same ultrasound probe state, arranging the states from large to small according to the state parameters, and selecting the first h ultrasound probe states as the ultrasound probe states.

[0038] In order to better implement the above method, an ultrasound therapy control system based on medical imaging data is also proposed. The system includes: a target detection area management module, a feature reference image management module, a first evaluation coefficient calculation module, a clarity evaluation value calculation module, a second evaluation coefficient calculation module and an information management module, wherein the target detection area management module is used to select a target detection area from a template image, the feature reference image management module is used to obtain common features and compose a feature reference image from the common features, the first evaluation coefficient calculation module is used to calculate a first evaluation coefficient of the ultrasound probe state, the clarity evaluation value calculation module is used to evaluate the clarity of the target image, the second evaluation coefficient calculation module is used to calculate a second evaluation coefficient of the ultrasound probe state, and the information management module is used to screen the ultrasound probe state and push information;
