Title: Scintillation camera
Inventor: KAWAGUCHI TOKIAKI
IPC: G01T1/164
Filed: 1985-01-16
Abstract: PURPOSE:To prevent the false image and to obtain good distribution image by counting the display radiation ray number per unit time, and varying the integration time of integration circuit by the integration signal which has inversely proportional time against the counted number signal. CONSTITUTION:A counter circuit 26 counts the display radiation ray number per unit time by the signal sent from a position calculation circuit 24, and a signal detection circuit 30 counts the incident radiation ray number per unit time by an electric signal from a photoelectronic multiplier 22, and inputs the signal S3 to integration time control circuit 27. The circuit 27 receives a calculation ratio signal S5 from the circuit 26, and outputs the integration signal S4 which has a time inversely proportional to S4, and the integration time of an integration circuit 23 is automatically controlled by the integration signal S4. In this way, since the integration time is shortened when the calculation rate of radiation is specially high, the outputs integrated will not overlap, and contrarily, the integration time will be prolonged when the radiation calculation ratio is low. Therefore no accuracy of position calculation is deteriorated.
