Abstract

PURPOSE:To only pick up fast moving peripheral edges of ventricular inner and outer walls and perform a detection of the ventricular inner and outer peripheral edges of high S/N ratio, by processing a subtraction of a pickup image at a certain point and that a prescribed length of time before. CONSTITUTION:The output image of an image intensifier 3 under a cinematographing is picked up by a cinecamera 5 and X-ray TV camera 6 through an optical distributor 4. An X-ray perspective image signal picked up by the TV camera 6 is fed to a monitor B and displayed. Simultaneously a video output signal from the TV camera 6 is recorded in a video recorder D through a reproducer C, reproduced after elapsed a prescribed length of time when the recording operation of one field or frame is finished and input to one of the input terminals in a subtraction circuit F. Here the video signal, when it is recorded by the video recorder D, simultaneously passes the reproducer C and is input to the other one of the input terminals in the subtraction circuit F. Then an output from the subtraction circuit F is input to a monitor G.
