Abstract

PURPOSE:To add biotic signal of a electrocardiogram and the like to a camera tube to pick up a X-ray penetration image and display superimposedly the both by residual image characteristic of the camera tube. CONSTITUTION:A biotic signal based on an electrocardiogram and the like is applied from a terminal 17, amplified 18, added to a pulse width modulation curcuit 19, triggered by output of a frequency divider curcuit 16, generates a pulse of a width in proportion to the output voltage of the amplifier curcuit 18, and with the after edge of the pulse, triggers a monostable multi-circuit 20. It is set to the optimal scanning electron beam quantity by a variable resistor 25 of the camera tube 7, but when an output pulse took place in the circuit 20, a transistor Tr 23 comes to ON for a specified pulse width time, the beam control voltage of the tube 7 becomes approximately OV and the electron beam quantity is set excessively. Only on this excessive part, the voltage of photoconductive plane is reduced and for several seconds a black part appears as a residual image, where the biotic signal is written to allow read it superimposed with the penetration image.
