Abstract: PURPOSE:To improve visibility of a catheter point end part by displaying a blood vessel map image, left as previously created and stored, and a real time perspective image, containing a catheter image, individually in two adjacently arranged TV monitors or adjacently in a scope of the one TV monitor. CONSTITUTION:In test injection of an imaging agent, photographing is performed before and after the injection, and a subtraction image between both photographed images, obtained by a picture processing device 1, is stored in a display image memory as a blood vessel map image and left as displayed in the first TV monitor 4 through the first display circuit 3. Next performing fluoroscopy when a catheter is inserted, a perspective image signal from a TV camera 2 is displayed in the second TV monitor 7 through a real time perspective image processor 5 and the second display circuit 6. In this way, the blood vessel map image and a real time perspective image, containing a catheter image, are individually displayed in two adjacently arranged TV monitors 4, 7. A display image of the first TV monitor 4 attains a function sufficiently as the blood vessel map image. Since a display image of the second TV monitor 7 is a catheter photographed image itself, visibility is improved of a catheter point end part.

Abstract: PURPOSE:To obtain an antenna system with excellent cross polarization identification by turning a sub reflection mirror by an angle delta so as to give a distortion of a(r)sin2phisin2delta, where (r) is a radial distance of the sub reflection mirror, phiis a circumferential angle and a(r) is a shape. CONSTITUTION:In turning the sub reflection mirror 2 around the optical axis of a ray 4 of light irradiated along the center axis of the primary radiator 1 by an angle delta, the shape of the sub reflection mirror is expressed as equation I, where (r) is a radial distance of the sub reflection mirror 2 and phi is a circumferential angle. In this equation, the 3rd and 4th terms are mirror surface distortion in turning the sub reflection mirror 2 around the optical axis of the ray 4 of light by delta degrees. When a main reflection mirror 3 is distorted in a direction of 45 deg. with respect to the center cross section curve 5', the mirror surface distortion of the main reflection mirror 3 is compensated by the term a(r) sin2phisin2delta causing a maximum distortion at phi=45 deg..
