管造影撮影装置。 In an angiography apparatus that photographs a blood vessel image by injecting a contrast medium from a catheter inserted into a blood vessel of a subject into a blood vessel to be imaged and taking X-ray photographs, the tip position of the catheter is displayed by an image display means. a first storage means for storing coordinate data of the marking position; a second storage means for storing an arbitrarily set enlargement ratio and an enlarged display time; image processing control means for reading the contents of the first and second storage means and outputting a processing command signal according to a predetermined image processing procedure based on an input signal for starting drug injection; Based on the coordinate data, magnification rate, and magnification display time included in the processing command signal given from the control means, the catheter tip portion is magnified at the specified magnification rate from the start of contrast medium injection to the magnification display time. What is claimed is: 1. An angiography imaging apparatus comprising an image processing means for displaying an image of a blood vessel, which is an imaging target, after an enlarged display time.
