[0026] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0027] See figure 1 An embodiment of the present invention provides a method for quantifying and extracting texture features of blood vessel wall images, which includes the following steps:
[0028] Step S101, using a medical imaging system to collect multiple frames of continuous blood vessel wall images.
[0029] In this embodiment, a medical imaging system is used to acquire N frames of continuous blood vessel wall images, where N is an image that covers at least one cardiac cycle. For example, the image acquisition frame rate FR of the medical imaging system is 100 frames per second, and the human heartbeat frequency f It is 60Hz / min, and the cardiac cycle Tc=60 / f=1 second; then N=m×FR×Tc=100m frames (m=1, 2, 3...). That is, N should be an integer multiple of 100, such as figure 2 Shown.
[0030] It is understandable that the medical imaging system ...
