INTERVENTIONAL NAVIGATION METHOD AND APPARATUS BASED ON IMAGE REGISTRATION, AND DEVICE AND MEDIUM

The present application belongs to the technical field of medical image processing. Disclosed are an interventional navigation method and apparatus based on image registration, and a device and a medium. The method comprises: extracting a first head end position of an intervention structure in an original DSA image in real time, and marking the first head end position, so as to obtain a marked DSA image; extracting a three-dimensional vascular model image, and registering the marked DSA image to the three-dimensional vascular model image, so as to obtain a registered image; searching the registered image for a second head end position corresponding to the intervention structure in the marked DSA image; and sending the second head end position to a display end, so as to display the second head end position. A mapping process of the registration method has the advantage of smoothness and reversibility, and a marked DSA image can be registered to a three-dimensional vascular model image with relatively high prec
