[0039] Figure 3 This is a structural block diagram of a carotid plaque measuring device in one embodiment. Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0041] The plaque measurement method for removing the influence of carotid artery systolic and diastolic contractions provided in this application embodiment can be applied in an application environment. This application environment includes an ultrasound processing device. The ultrasound processing device first acquires carotid adventitia data and carotid plaque data at preset segments in a carotid ultrasound image. The preset segments include at least one of the common carotid artery, external carotid artery, and internal carotid artery. For each preset segment, magnified carotid adventitia data at maximum adventitia diastolic state in the preset segment is obtained based on the carotid adventitia data of that preset segment. Actual plaque data for the corresponding segment is obtained based on the magnified carotid adventitia data of each preset segment.

[0042] In one embodiment, such as Figure 1 As shown, a method for measuring carotid artery plaque is provided.

[0043] The method includes:

[0044] Step S100: Acquire carotid adventitia data and carotid plaque data at preset segments in the carotid ultrasound image, wherein the preset segments include at least one of the common carotid artery, external carotid artery and internal carotid artery;

[0045] In this step, the adventitia data and plaque data of the carotid artery at preset segments in the carotid ultrasound image are obtained. The preset segments include at least one of the common carotid artery, external carotid artery and internal carotid artery, providing underlying data support for the subsequent extraction of actual plaque data.

[0046] Step S200: For each preset segment, obtain magnified carotid adventitia data at the maximum adventitia diastolic state in the preset segment based on the carotid adventitia data of the preset segment.

[0047] The carotid adventitia data and the carotid plaque data are segmented to generate common carotid artery data, external carotid artery data, and internal carotid artery data; wherein, the common carotid artery data includes common carotid adventitia data and common carotid plaque data, the external carotid artery data includes external carotid adventitia data and external carotid plaque data, and the internal carotid artery data includes external carotid adventitia data and external carotid plaque data;

[0048] Specifically, in this step, the carotid adventitia data and the carotid plaque data are segmented to distinguish the common carotid artery data, external carotid artery data and internal carotid artery data. This segmentation is based on the fact that the carotid artery includes the common carotid artery, external carotid artery and internal carotid artery.

[0049] Furthermore, by segmenting the data, the data on the common carotid artery can be classified, acquired, and processed, thereby improving the accuracy of data processing.

[0050] Next, the amplified carotid adventitia data at the maximum adventitia diastolic state in the preset segment is obtained based on the carotid adventitia data of the preset segment.

[0051] Step S300: Obtain the actual plaque data of the corresponding segment based on the magnified carotid adventitia data of each preset segment.

[0052] The magnified data of the common carotid artery at maximum adventitia diastole was obtained from the adventitia data of the common carotid artery, the magnified data of the internal carotid artery at maximum adventitia diastole was obtained from the adventitia data of the internal carotid artery, and the magnified data of the external carotid artery at maximum adventitia diastole was obtained from the adventitia data of the external carotid artery.

[0053] Specifically, based on actual clinical experience, it is known that the maximum diastolic state of each segment of an artery is consistent. Therefore, by obtaining magnified data of the common carotid artery, the internal carotid artery, and the external carotid artery, the influence of arterial contraction and relaxation caused by respiration on plaque data can be eliminated.

[0054] That is, although the actual human carotid ultrasound image shows different degrees of diastole in each arterial segment, by magnifying the image, the magnified data of the common carotid artery, the internal carotid artery, and the external carotid artery at the maximum adventitia diastole can be obtained. This can filter out the influence of carotid artery contraction and relaxation on plaque measurement and improve the accuracy of plaque data acquisition.

[0055] Specifically, the method acquires carotid adventitia data and carotid plaque data at preset segments in carotid ultrasound images. The preset segments include at least one of the common carotid artery, external carotid artery, and internal carotid artery. For each preset segment, magnified carotid adventitia data at maximum adventitia diastole in the preset segment is obtained based on the carotid adventitia data of the preset segment. Actual plaque data for the corresponding segment is obtained based on the magnified carotid adventitia data of each preset segment. Thus, by magnifying each segment of the carotid artery to its maximum diastole before acquiring plaque data, the influence of carotid artery contraction and relaxation on plaque measurement is eliminated, improving the accuracy of plaque data measurement.

[0056] In another embodiment of the present invention, the step of obtaining amplified carotid adventitia data at the maximum adventitia diastolic state in the preset segment based on the carotid adventitia data of the preset segment specifically includes:

[0057] Step S311: Obtain the radius of the circumcircle of the adventitia of the preset segment based on the carotid adventitia data of the preset segment.

[0058] The radius of the circumcircle of the adventitia of each segment of the common carotid artery was obtained based on the adventitia data.

[0059] Step S312: Obtain the maximum value among the radii of each outer membrane circumcircle and record it as the maximum outer membrane circumcircle radius;

[0060] The maximum value among the circumcircle radii of each outer membrane is obtained and recorded as the maximum circumcircle radius of the outer membrane.

[0061] Next, the diastolic state of the arterial segment corresponding to the maximum adventitia circumcircle radius is obtained and recorded as the arterial segment in the maximum adventitia diastolic state.

[0062] Step S314: Magnify the carotid adventitia data according to the radius of the maximum adventitia circumcircle to obtain magnified carotid adventitia data.

[0063] In another embodiment of the present invention, the step of amplifying the carotid adventitia data based on the maximum adventitia circumcircle radius to obtain amplified carotid adventitia data includes:

[0064] Step S710: For each position in the preset segment other than the position of the maximum outer membrane circumcircle radius, obtain the ratio of the maximum outer membrane circumcircle radius to the outer membrane circumcircle radius at the position;

[0065] Step S720: Magnify the various locations according to the calculated ratio to obtain magnified carotid adventitia data.

[0066] In another embodiment of the present invention, the step of enlarging the arterial segment in the carotid adventitia data, excluding the segment in the maximum adventitia-diastolic state, to the radius of the maximum adventitia circumcircle corresponding to the segment in the maximum adventitia-diastolic state, and summing the enlarged arterial segment with the segment in the maximum adventitia-diastolic state, and recording it as the enlarged carotid artery data, specifically includes:

[0067] Step S3141: Obtain the circumradius of the adventitia of each segment of the common carotid artery except for the segment in the maximum adventitia diastolic state, and record it as the circumradius of the adventitia to be enlarged;

[0068] Step S3142: Divide the value of the maximum outer membrane circumcircle radius by the circumcircle radius of each outer membrane to be magnified, and generate each specific outer membrane magnification factor; wherein, a specific outer membrane magnification factor corresponds to a circumcircle radius of an outer membrane to be magnified.

[0069] Step S3143: Magnify the arterial segments in the adventitia data of the common carotid artery, excluding the arterial segments in the maximum adventitia diastolic state, according to the corresponding specific adventitia magnification factor, and summarize the magnified arterial segments with the arterial segments in the maximum adventitia diastolic state, and record them as the magnified common carotid artery data.

[0070] Specifically, the following example illustrates the steps from S3141 to S3141 above, such as... Figure 2 As shown, Figure 2 This is a schematic diagram of the common carotid artery. Figure 2 In the diagram, A, B, and C represent the circumradii of the adventitia at three points on the common carotid artery. The circumradii of the adventitia at point A are 10, at point B are 5, and at point C are 2.

[0071] Furthermore, as can be seen from step S312, the value of the circumscribed circle radius of the adventitia at point A is 10, which is the maximum. Therefore, the circumscribed circle radius of the adventitia at point A is the maximum circumscribed circle radius of the adventitia, with a value of 10. According to step S313, the diastolic state of the arterial segment corresponding to the circumscribed circle radius of the adventitia at point A is the arterial segment in the maximum adventitia diastolic state.

[0072] Next, according to step S3141: obtain the circumradius of each adventitia in the arterial segment excluding the segment in the maximum adventitia diastolic state in the adventitia data of the common carotid artery, and record it as the circumradius of the adventitia to be magnified. That is, at this time, the values ​​of the circumradius of the adventitia at point B and the circumradius of the adventitia at point C are both the circumradius of the adventitia to be magnified.

[0073] Then, according to step S3142: divide the value of the maximum outer membrane circumcircle radius by the outer membrane circumcircle radius of each outer membrane to be magnified, and generate each specific outer membrane magnification factor, that is, divide the outer membrane circumcircle radius at point A by the outer membrane circumcircle radius at point B, and then divide the outer membrane circumcircle radius at point A by the outer membrane circumcircle radius at point C.

[0074] Furthermore, the radius of the circumscribed circle of the adventitia at point A divided by the radius of the circumscribed circle of the adventitia at point B is 10 / 5, which equals 2. That is, for segment B, the specific adventitia magnification factor is 2, while the value of B itself is 5. Therefore, according to step S3143: the arterial segments in the adventitia data of the common carotid artery, excluding the segment in the maximum adventitia diastolic state, are magnified according to the corresponding specific adventitia magnification factor. After calculation, the radius of the circumscribed circle of the adventitia after magnification of segment B is 10, which is the same as the radius of the circumscribed circle of the adventitia at point A.

[0075] The radius of the circumcircle of the adventitia at point A divided by the radius of the circumcircle of the adventitia at point C is 10 / 2, which equals 5. This means that for segment C, the specific adventitia magnification factor is 5, while the value of B itself is 2. Therefore, according to step S3143: the arterial segments in the common carotid artery adventitia data except for the segment in the maximum adventitia diastolic state are magnified according to the corresponding specific adventitia magnification factor. After calculation, the radius of the circumcircle of the adventitia after magnification of segment C is 10, which is the same as the radius of the circumcircle of the adventitia at point A.

[0076] Furthermore, through the above steps, the circumradius of the adventitia of each artery at the common carotid artery is made the same, thereby filtering out the influence of carotid artery contraction and relaxation.

[0077] Of course, during the magnification of the common carotid artery, internal carotid artery, and external carotid artery, the corresponding plaque data is also magnified. Therefore, obtaining plaque data after magnification is both accurate and efficient.

[0078] Similarly, the calculation method for the dilation of the internal carotid artery and external carotid artery is the same as that for the common carotid artery, and will not be repeated here.

[0079] In another embodiment of the present invention, the step of acquiring carotid adventitia data and carotid plaque data at predetermined segments in a carotid ultrasound image, wherein the predetermined segments include at least one of the common carotid artery, external carotid artery, and internal carotid artery, specifically includes:

[0080] Step S110: Acquire the loaded carotid ultrasound image;

[0081] Step S120: Perform image segmentation on the carotid ultrasound image and generate the carotid adventitia data and the carotid plaque data.

[0082] In another embodiment of the invention, the step of obtaining amplified internal carotid artery data at the maximum adventitia diastolic state of each segment of the internal carotid artery based on the adventitia data specifically includes:

[0083] Step S321: Obtain the radius of the circumcircle of the adventitia of each segment of the internal carotid artery based on the adventitia data;

[0084] Step S322: Obtain the maximum value among the radii of each outer membrane circumcircle and record it as the maximum outer membrane circumcircle radius.

[0085] Step S323: Obtain the diastolic state of the arterial segment corresponding to the maximum adventitia circumcircle radius, and record it as the arterial segment in the maximum adventitia diastolic state;

[0086] Step S324: Enlarge the arterial segments in the internal carotid artery adventitia data, excluding the arterial segments in the maximum adventitia diastolic state, to the radius of the maximum adventitia circumcircle corresponding to the arterial segments in the maximum adventitia diastolic state, and summarize the enlarged arterial segments with the arterial segments in the maximum adventitia diastolic state, and record them as the enlarged internal carotid artery data.

[0087] Further, the process of enlarging the arterial segments in the internal carotid artery adventitia data, excluding the segment in maximum adventitia diastole, to the radius of the maximum adventitia circumcircle corresponding to the segment in maximum adventitia diastole, and summing the enlarged arterial segments with the segment in maximum adventitia diastole, and recording this as the enlarged internal carotid artery data, specifically includes:

[0088] Step S3241: Obtain the circumradius of the adventitia of each segment of the internal carotid artery, excluding the segment in the maximum adventitia diastolic state, and record it as the circumradius of the adventitia to be enlarged.

[0089] Step S3242: Divide the value of the maximum outer membrane circumcircle radius by the circumcircle radius of each outer membrane to be magnified, and generate each specific outer membrane magnification factor; wherein, a specific outer membrane magnification factor corresponds to a circumcircle radius of an outer membrane to be magnified.

[0090] Step S3243: Magnify the arterial segments in the adventitia data of the internal carotid artery, excluding the arterial segments in the maximum adventitia diastolic state, according to the corresponding specific adventitia magnification factor, and summarize the magnified arterial segments with the arterial segments in the maximum adventitia diastolic state, and record them as the magnified internal carotid artery data.

[0091] In another embodiment of the invention, the step of obtaining amplified external carotid artery data at the maximum adventitia diastolic state of each segment of the external carotid artery based on the adventitia data specifically includes:

[0092] Step S331: Obtain the radius of the circumcircle of the adventitia of each segment of the external carotid artery based on the adventitia data;

[0093] Step S332: Obtain the maximum value among the radii of each outer membrane circumcircle and record it as the maximum outer membrane circumcircle radius.

[0094] Step S333: Obtain the diastolic state of the arterial segment corresponding to the maximum adventitia circumcircle radius, and record it as the arterial segment in the maximum adventitia diastolic state;

[0095] Step S334: Enlarge the arterial segments in the external carotid artery adventitia data, excluding the arterial segment in the maximum adventitia diastolic state, to the radius of the maximum adventitia circumcircle corresponding to the arterial segment in the maximum adventitia diastolic state. Then, summarize the enlarged arterial segments with the arterial segment in the maximum adventitia diastolic state and record them as the enlarged external carotid artery data.

[0096] Further, the process of enlarging the arterial segments in the external carotid artery adventitia data, excluding the segment in maximum adventitia diastole, to the radius of the maximum adventitia circumcircle corresponding to the segment in maximum adventitia diastole, and summing the enlarged arterial segments with the segment in maximum adventitia diastole, and recording this as the step of enlarging the external carotid artery data, specifically includes:

[0097] Step S3341: Obtain the circumradius of the adventitia of each segment of the external carotid artery, excluding the segment in the maximum adventitia diastolic state, and record it as the circumradius of the adventitia to be enlarged;

[0098] Step S3342: Divide the value of the maximum outer membrane circumcircle radius by the circumcircle radius of each outer membrane to be magnified, and generate each specific outer membrane magnification factor; wherein, a specific outer membrane magnification factor corresponds to a circumcircle radius of an outer membrane to be magnified.

[0099] Step S3343: Magnify the arterial segments in the external carotid artery adventitia data except for the arterial segments in the maximum adventitia diastolic state according to the corresponding specific adventitia magnification factor, and summarize the magnified arterial segments with the arterial segments in the maximum adventitia diastolic state, and record them as the magnified external carotid artery data.

[0101] Magnified common carotid artery data, magnified internal carotid artery data, and magnified external carotid artery data were extracted separately;

[0103] That is, the step of obtaining the actual plaque data of the corresponding segment based on the magnified adventitia data of each preset segment includes: identifying the plaque data of the plaque in the magnified carotid ultrasound image.

[0104] In this step, during the magnification of the common carotid artery, internal carotid artery, and external carotid artery, the corresponding plaque data is also magnified. Therefore, by extracting the magnified common carotid artery data, the magnified internal carotid artery data, and the magnified external carotid artery data respectively, and then summarizing the magnified common carotid artery plaque data, the magnified internal carotid artery plaque data, and the magnified external carotid artery plaque data to generate the actual plaque data, accurate plaque data can be obtained.
