Abstract
PURPOSE: To make high in tomogram pick up speed and to lower the cost for the unit without using a computer, by processing analogically the picture of the distribution of radiant ray absorbing rate in tomogram surface orthogonal to the body axis of a human body.
CONSTITUTION: A number of X-ray beams 12 spread in fan shape from the X-ray tube 11 are radiated on the objective 13, and the beams 12 transmitted are incident to the X-rays-photo converters 14 of many number arranged on a row. Further, the X-ray tube 11 and the converter 14 are unified and they are rotated around the object 13 with the rotation control unit 15, the data representing the projection profile obtained every revolution is fed to the analog convoluver 16, and convolution process is made at the analog photo signal stage. After that, the electric luminance signal and the location signal are fed to the analog back projector 17 where video signal is formed to display it on the CRT 18 such as monitor television unit. Thus, tomogram picture is obtained at the same time when the end of revolution of the radiant ray source, allowing to speed up the unit.
