ABSTRACT:
In registration of images in digitized subtracted angiography, X-rays irradiate a patient's body. A first digitized mask image is acquired without an injection of the contrast agent into the body, then the contrast agent is injected into the body, and a second digitized contrast image is acquired. The mask image is divided with regular geometrical patterns and a registration is made of the mask image relative to the contrast image through the use of landmarks defined at the corners of the geometrical patterns. These two images are subtracted after registration, and the subtracted image is displayed. The robustness of the landmarks is furthermore tested, and if the robustness is insufficient, a subdivision is made of the regular geometrical patterns.
