PURPOSE:To prepare high resolution X-ray diagnosing information by making the output optical image of an image intensifier into plural pictures to reduce the number of picture elements in an X direction and in a Y direction at an image pick-up type input side by a picture distributing device, picture-inputting this with plural image pick-up systems and re-constituting an image pick-up signal. CONSTITUTION:The optical output image of I. I.(image intensifier) 2 is divided into four pictures to make both an (x) direction and a Y direction into 1/2 by a 4-picture output type picture distributing device 10 to use an optical fiber line pencil and four image pick-up systems. Thereafter, these pictures are re-con stituted and one picture to restore to the number of the picture element of an original picture is obtained. Thus, without depending on the characteristic improvement of the image pick-up system, an X-ray diagnosing picture to satisfy the specifications of 2000X2000 picture elements or above per picture required by a DF(digital fluorography) picture can be obtained. |
