Abstract

PURPOSE: To obtain a scintigram of an optimum density independently of the period of heart pulses by setting previously the required number of heart pulses to control a unit in case that the scintigram (integration distribution image) of the radioactive isotope accumulated in the heart, etc.
CONSTITUTION: The radiant ray from the radioactive isotope gathered in the heart of tested person 1 is detected by detector 2, and X and Y coordinate signals indicating the position and timing signal Z generating a luminous point are sent from scinti- camera main body 3 to display unit 7 to display the luminous point, and a scintigram is obtained on film 8 of camera 8. In this case, the number of heart pulses required for obtaining the light exposure time of an optimum density is set to preset counter 9 previously. Then, tuning analysis circuit 5 is operated by photographing start signal 13, and gate circuit 6 is opened at every period, when the heart movement is least, on a basis of heart electric signals 14 from tested person 1 to cause signal Z to pass through gate circuit 6; and when the counted value of counter 9 reaches the set number of heart pulses, gate circuit 10 is closed to break signal Z passing through circuit 6, thereby obtaining a good photograph recording time.
