Blood vessel guide wire tracking method, device and equipment based on medical image and medium

The invention relates to a blood vessel guide wire tracking method and device based on a medical image, equipment and a medium, and the method comprises the steps: segmenting a guide wire in a medical image according to three different guide wire widths, and obtaining a first segmented image, a second segmented image and a third segmented image corresponding to the three different guide wire widths; and then correcting and optimizing the other two images by utilizing the advantages of the segmented images with different guide wire widths, and outputting the updated second segmented image as a guide wire segmented image after the connected domain in each segmented image is corrected for multiple times. By adopting the method, the problems of too high false detection and missing detection and inaccurate segmentation of the head end and the tail end of the guide wire under the condition of partial specific images can be solved, so that the real-time accurate tracking of the guide wire is realized. 本申请涉及一种基于医学影像的
