Problems solved by technology

[0004] It can be seen that in the prior art, the location of the suspected vascular stenosis area is completed based on the doctor's personal experience, which may cause the speed of locating the suspected vascular stenosis area to be relatively slow due to the lack of experience of the doctor, or even possible Areas of suspected stenosis are missed, which reduces the speed and accuracy of locating the area of ​​suspected stenosis

Embodiment Construction

[0070] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0071] figure 1 It is a flow chart of a method for locating a suspected vascular stenosis region according to an embodiment of the present invention. Such as figure 1 As shown, the method includes the following steps:

[0072] Step 101, scan the blood vessel to be inspected, and acquire the image of the blood vessel to be inspected.

[0073] In this step, the medical imaging device scans the blood vessel to be inspected, and obtains a three-dimensional reconstructed image of the blood vessel to be inspected.

[0074] Step 102, performing curve fitting on the cross-sectional diameter of the blood vessel according to the image of the blood vessel to be inspected.

[0075] figure 2 It is a flow chart of the curve fitting method when performing curve ...

Abstract

The invention discloses a method for positioning a suspected blood vessel narrow area. The method comprises the following steps of: acquiring an image of a blood vessel to be examined; carrying out curve fitting on the diameter of the cross section of the blood vessel according to the image of the blood vessel to be examined; extracting the low point of the fitted curve as a suspected blood vessel narrow point; and determining the suspected blood vessel narrow area where the suspected blood vessel narrow point is located. Meanwhile, the invention also discloses a system for positioning the suspected blood vessel narrow area. The method and the system of the invention can be used for increasing the positioning speed and accuracy of the suspected blood vessel narrow area.

Description

technical field [0001] The invention relates to the field of medical imaging, in particular to a method and system for locating a suspected vascular stenosis area. Background technique [0002] Medical imaging provides a new means of non-invasive examination. Medical imaging equipment, such as magnetic resonance imaging (MRI) scanners, computer tomography (CT) scanners, scans the patient's area to be examined and obtains the information to be examined. An image of the area, which can then be analyzed by a doctor. [0003] In clinical practice, it is sometimes necessary to locate the suspected area of ​​vascular stenosis in a patient, and then the doctor further judges the area of ​​suspected vascular stenosis, so as to determine the real area of ​​vascular stenosis. In the prior art, the method for locating the area of ​​suspected vascular stenosis is as follows: firstly, the medical imaging equipment scans the blood vessel to be inspected, and obtains the image of the bloo...
