IMAGE DISPLAY METHOD AND APPARATUS AND FLUOROSCOPIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To miniaturize a display part by displaying an actual image and a control image on a common display device at different timings in the displaying of the actual image of a subject obtained by fluoroscopy and the control image. SOLUTION: During the fluoroscopy, firstly, an X-ray tube 2 is driven by an irradiation control part 12 before the injection of a contrast medium to take a fluoroscopic image of a subject 8 by a video camera 6 and an image data of the fluoroscopic image is stored into a frame memory while being sent to a display part 16 through a switch gear to be displayed as fluoroscopic image. In this process, the fluoroscopic image is displayed in a circular frame and an operator operates an operating part 20 to store the image into a mask memory as mask image. Then, the contrast medium is injected into the subject 8 to take a fluoroscopic image and an image data of the fluoroscopic image taken is stored into the frame memory likewise while a fluoroscopic image containing a blood vessel image clarified by the contrast medium is shown on a display part 16.
