Vascular image acquisition method, apparatus, angiography system, and program product

Abstract

This application relates to a method, apparatus, angiography system, and program product for acquiring vascular images. The method is applied to an angiography system. It involves controlling a scanning device within the angiography system to move towards a destination position at an initial moving speed. During this movement, a first subtraction image and a second subtraction image of the target object in the current frame are acquired. Based on the first and second subtraction images, the initial moving speed is corrected. The corrected initial moving speed is then used as the new initial moving speed, and the process of acquiring the first subtraction image of the target object in the current frame and the second subtraction image of the previous frame during the movement is repeated until the scanning device reaches the destination position. Using the vascular image acquisition method provided in this embodiment can yield more accurate vascular images.
