Abstract
The invention relates to a video display device which includes a memory for storing intensity values for each pixel of the video display. Connected with the memory is a persister which decreases the intensity values as a selectable function of time such that a displayed image will appear to fade. Also connected with the memory is an input for increasing specific intensity values in response to the receipt of input data corresponding to that specific display pixel. The invention further relates to a scintillation camera in combination with the video display device in which input data indicates the occurrence of a radiation caused scintillation at some corresponding coordinate position and in which the rate of image fading is consonant with the rate of data acquisition, whereby a real-time display of the passage of a radioisotope through a patient may be produced.
