Abstract
PURPOSE:To obtain a well contrasted and fine scintigram, by dispersedly indicating plural brilliant points around an indicated brilliant point of incident gamma rays, even in case when radioactive isotope concentration distribution in a human body is low and the information density is small. CONSTITUTION:Gamma rays radiated from a patient's body are detected 1, signals X and Y indicating the positions are put out from a position calculating circuit 2 and held 5 for a given period of time. These signals are continuously held during the time when plural pulses, which are synchronized with an unblank singal UBK, are put out from a pulse generating circuit 7. And thus held positions signals X and Y are finely deflected in the neighborhood of incoming position of the gamma rays by a microdeflection circuit 6 every time a pulse is put out from the circuit 7, and every incident gamma rays, plural brilliant points in the neighborhood of the incoming position are dispersedly indicated on a CRT4.
