A new type of gamma cameras is described that give useful image information over its entire crystal face. The array of photo-multiplier tubes (PMTs) of the camera is divided into the four sub-arrays which outputs are weighted into the same equivalent solid angle functions (ESAFs) respectively, called as the mean detector-response functions (MRFs). The high resolution imaging system of nuclear medicine is studied and designed in this paper by the applications of digital electronics, digital signal processing and tile maximum likelihood estimation, which of position, energy and the depth of a scintillation event for the high resolution image acquisition.
