ABSTRACT:
A scintillation camera including a memory having a plurality of addresses corresponding to the elements of the matrix-like divided image of a scintigram and to the points in the camera head for registering radiation. The addresses in the memory are designated to correspond to incidence position signals of points of radiation determined by a position-calculating circuit. A pulse-height analyzer also receives the signals of radiation registered by the camera head and issues an unblanking signal to control apparatus if the signal is significantly stronger than background noise. The control apparatus, triggered by the unblanking signal, initiates the comparison of the content of the designated address in memory with a predetermined minimum value of radiation in a comparator and when the content is less than the minimum value the control apparatus adds one to the content and restores the increased content to the designated address. When the content is at least equal to the minimum value, the control apparatus issues the unblanking signal to display apparatus to display the radiation at the designated address. A timer stops access of the unblanking signals to the display apparatus after a preset time, thus excluding display at those elements of the display wherein the accumulated radiation is less than the minimum at the expiration of the preset time.
