PURPOSE:To improve the accuracy of diagnosis with a small amount of exposure of X rays, by performing the image scan-reading with use of an X-ray photograph as a memory medium. CONSTITUTION:The laser light 2 given from a laser light source 1 is scanned by a galvanometer mirror 3 on an image carrier 4 and in a main scanning direction A. The carrier A is shifted in a subscanning direction B and receives the 2- dimensional scan by the light 2. The light produced from the scanning enters a light transmitting member 5 through an incident end 5a of the member 5 and travels into the member 5 to be condensed on the light receiving surface of a photomultiplier 6. A cut filter 7 is put in an attachable/detachable way between the multiplier 6 and the circular output end of the member 5 to cut the wavelength band of the light 2 and transmits only the wavelength band of the flash light. The output of the multiplier 6 undergoes a necessary process through an image signal processing circuit and then receives a necessary display. |
