ABSTRACT:
An apparatus is specialized in diagnosing a vascular system in an organism. The diagnostic apparatus is preferable especially to inspection of a circulatory system such as a blood vessel. The inspection can be carried out by obtaining a longitudinal structual image of a lumen of the vascular system and a stenosis index of the lumen. In order to accomplish it, the apparatus comprises an element for fluorographing the vascular system by X-rays, an element for obtaining a plurality of fluoroscopic images based on the X-ray fluoroscopic image signals supplied, an element for ultrasonic probing which has an ultrasonic probe inserted into the vascular system with a catheter, an element for obtaining a plurality of tomographic images based on the ultrasonic tomographic image signals supplied, an element for determining structure of the vascular system based on the plurality of fluoroscopic images and the plurality of tomographic images, and an element for displaying the structure of the vascular system.
