摘要： A method and an apparatus for motion visualization of a moving object in angiographic images are described. In a preferred embodiment of the method, first a mask image of the object of interest is acquired and a sequence of angiographic images of the object in different phases of motion of the object is acquired. Then, a first angiographic subtraction image and at least a second angiographic subtraction image are generated by subtracting the angiographic images from the mask image. Subsequently, a twice subtracted image is generated by subtracting the first angiographic subtraction image from the second angiographic subtraction image. In this way a double subtraction, i.e. a twice subtracted angiography is performed, to facilitate the assessment of the motion.
