Description

Technical Field

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0044] Currently, carotid artery scans can assess the presence of carotid atherosclerosis by measuring intima-media thickness (IMT). This measurement involves capturing a video of the carotid artery, capturing pixel points along its boundaries, and calculating the IMT based on the pixel difference. However, there is a lack of an effective method for scanning the carotid arteries to ensure accurate video scans.

[0045] Example 1

[0046] In view of the above shortcomings, the present invention proposes a scanning method for carotid artery transverse membrane, such as Figure 1 Shown, including:

[0047] S10: moving the ultrasound probe according to the coordinate system until the blood vessel contour is obtained, where the coordinate system is set with the horizontal direction along the blood vessel as the x-axis, the horizontal direction perpendicular to the blood vessel as the y-axis, and the vertical direction as the z-axis;

[0048] During the movement of the ultrasound probe, it is necessary to ensure that it remains in close contact with the human neck. Figure 2 Shown, including:

[0049] S11: Drag the ultrasound probe to the carotid artery and rotate it along the x-axis until it fits against the neck. It should be noted that the fit between the ultrasound probe and the neck is verified using the following method:

[0050] S111: Determine whether the center-of-gravity deflection angle of the area image is less than a deflection threshold. During ultrasound scanning, the area image of the carotid artery appears elliptical, and the deflection angle between the center of gravity of the ellipse and the midline of the ultrasound image to which the area image belongs is the center-of-gravity deflection angle.

[0051] S112: If not, rotate the ultrasonic probe along the x-axis direction until the center of gravity deflection angle is less than or equal to the deflection threshold, and the deflection threshold is preferably set to 0.4 rad.

[0052] S12: Obtain the area image of the blood vessel contour;

[0053] S13: If the area image is smaller than the area image threshold, move back and forth along the y-axis until the area image is greater than or equal to the area image threshold. The above area image threshold is 1000 pixels. When the obtained area image is smaller than this area image threshold, it is determined that the blood vessel contour is not effectively recognized.

[0054] It should be added here that in order to ensure the effect of obtaining the blood vessel contour, it needs to be placed at the center of the ultrasonic image as much as possible, and the implementation method can be achieved by moving the ultrasonic probe along the y-axis.

[0055] S20: If the membrane structure of the blood vessel contour is obtained by scanning, move the ultrasonic probe along the x-axis direction to the carotid sinus part and obtain the x-direction image of the membrane structure; the pixel value of the above membrane structure in the ultrasonic image will be greater than the set membrane structure pixel threshold (such as 50 pixels), so as to effectively distinguish the blood vessel contour from the membrane structure. During the process of moving the ultrasonic probe along the x-axis direction, the situation of losing the membrane structure image may occur, which may be caused by external factors such as blood vessel pulsation. At this time, the ultrasonic probe will maintain the moving state for at least 1 s or more. If the membrane structure is still not searched, the scanning will be repeated until the membrane structure is obtained.

[0056] During the scanning process, the ultrasonic probe will obtain the real-time image and / or video of the membrane structure in the x-direction in real time for later processing.

[0057] At the same time, it should be added here that when the ultrasonic probe obtains the membrane structure image for the first time, the ultrasonic probe will record the force applied to the ultrasonic probe and use this as the benchmark for the force applied by the subsequent membrane structure.

[0058] S30: When the ultrasonic probe meets the reverse movement condition, rotate the ultrasonic probe along the y-axis direction to obtain the y-direction image of the membrane structure.

[0059] Among them, the reverse movement conditions include that the lateral force applied to the ultrasonic probe is greater than the lateral force threshold (such as 2.5 N), and the number of times of losing the blood vessel contour is greater than the loss threshold. The above lateral force refers to the contact force of the ultrasonic probe on the neck. And the loss threshold is usually set to 2 times or more, and is adjusted according to different usage situations.

[0060] When the reverse movement condition is met, the ultrasonic probe rotates along the y-axis, so as to obtain more images of the membrane structure and even the blood vessel contour in the y-axis direction, and perform post-processing together with the images in the x-axis direction as the result image of the scanning.

[0061] Then execute S40: Drive the ultrasonic probe to move in the reverse direction. It should be noted that during the reverse movement process, the moving distance needs to meet the range of the safety distance. The setting of the safety distance is as follows:

[0062] During the execution of step S20, it is determined by the ultrasonic probe whether there is a vascular bifurcation in the carotid sinus. If there is a vascular bifurcation, it is recorded as the first position; if there is no vascular bifurcation but the reverse movement condition is met, the position at this time is recorded as the second position.

[0063] After that, during the reverse movement, by calculating the difference between the current position and the first position or the second position, the range of the safety distance is obtained. The ultrasonic probe needs to move within the range of the safety distance during the reverse movement to ensure that the subsequent rotation around the z-axis will not cause damage to the patient.

[0064] The scanning method for the carotid transverse membrane provided by the embodiment of the present invention determines the vascular contour, and then scans along the x-axis to obtain the image of the membrane structure in the x-axis direction. And to ensure the scanning effect of the membrane structure, the image in the y-direction is obtained when the ultrasonic probe moves back in the reverse direction, so as to ensure the scanning effect.

[0065] Embodiment Two

[0066] Based on Embodiment One, the embodiment of the present invention further proposes that on the basis that the membrane structure is not obtained in the execution of step S20, the ultrasonic probe scans repeatedly until the membrane structure is obtained. As Figure 3 shown, it includes:

[0067] S21: If the membrane structure with the vascular contour is not obtained by scanning, rotate the ultrasonic probe along the y-axis by an angle of 0.2 rad, and determine again whether the membrane structure is obtained; since the carotid artery cannot be guaranteed to be completely consistent with the x-axis direction, the role of rotating the ultrasonic probe along the y-axis is to expand the search range in the y-axis direction.

[0068] S22: If so, move the ultrasonic probe along the x-axis direction to the carotid sinus and obtain the x-direction image of the membrane structure;

[0069] S23: If not, rotate along the x-direction and determine again whether the membrane structure with the vascular contour is obtained; if the membrane structure is not obtained by rotating along the y-axis, the search area is expanded by rotating along the x-axis. It should be noted here that during the execution of step S22 and step S23, there is a search times threshold. When the search times is greater than this search threshold, the same type of search will no longer be performed.

[0070] S24: If it is negated again, confirm that the area scanning is completed and move along the x-axis to the adjacent area. It should be added here that the instrument to which the ultrasonic probe belongs is provided with a counter, and a +1 operation is performed during the execution of step S24, and S22 - S24 are repeated in this way until the carotid transverse membrane scanning is completed.

[0071] Embodiment Three

[0072] Based on Embodiment 1, in an embodiment of the present invention, as Figure 4 shown, step S30 further includes:

[0073] S31: When the rotation angle of the ultrasonic probe along the y-axis is greater than the first angle threshold (such as 0.25 rad); rotate the ultrasonic probe in the reverse direction along the x-axis, and determine whether the rotation angle of the y-axis is less than the second angle threshold (such as 0.15 rad); the above-mentioned second angle threshold is used for the use scenario of neck scanning when the ultrasonic probe moves to the patient's chin area. By setting the second rotation threshold, damage to the patient can be avoided.

[0074] S32: When the rotation angle of the ultrasonic probe along the y-axis is less than the first angle threshold, increase the rotation angle of the y-axis to be greater than or equal to the first angle threshold. When the ultrasonic probe moves in the reverse direction along the x-axis, it is first necessary to make the rotation angle of the y-axis greater than or equal to the first angle threshold to obtain an image of the membrane structure in the y direction.

[0075] It should be added here that in the process of determining whether the rotation angle of the y-axis is less than the second angle threshold, it specifically includes:

[0076] S311: If so, rotate the ultrasonic probe in the reverse direction along the x-axis;

[0077] S312: If not, reduce the rotation angle of the y-axis to be less than or equal to the second angle threshold.

[0086] If not, rotate in the x-direction and determine again whether the membrane structure of the blood vessel contour is obtained;

[0087] If it is negated again, confirm that the area scanning is completed and move along the x-axis to the adjacent area.

[0092] If not, rotate in the x-direction and determine again whether the membrane structure of the blood vessel contour is obtained;

[0093] If it is negated again, confirm that the area scanning is completed and move along the x-axis to the adjacent area.
