Abstract: A radiation detection/imaging system includes a first set of radiation detectors spaced from each other in a first direction and a second set of radiation detectors spaced from each other in the first direction. The second set of radiation detectors is positioned laterally adjacent the first set of radiation detectors and the radiation detectors of the first and second sets of radiation detectors are arranged in an alternating or staggered pattern in the first direction. A composite image can be formed of the passage of radiation through an object acquired by the first and second sets of radiation detectors as the object is translated by the first and second sets of radiation detectors.

Abstract: A radiation detection system is operative for converting (1, 2) a radiation event into an electrical signal having an amplitude related to the energy of said radiation event, converting (3, 6) at least a portion of the electrical signal into a count value related to the amplitude of the electrical signal and determining (5) the energy of the radiation event from the count value.

Abstract: A gamma ray camera A includes a crystal array S which includes a plurality of pixels 4 each of which outputs a pixel signal in response to receiving a gamma ray. A first circuit (6, 8, 10, 12, 14 and 22) outputs for each pixel 4 of the crystal array S, when a pixel signal output by the pixel 4 has a predetermined relation to a reference signal, a threshold signal related to the position of the pixel 4 in the crystal array S. A second circuit (18, 20, 24, 26, 28, 30 and 32) outputs a counter value for each pixel signal having a predetermined relation to its threshold signal. Lastly, a third circuit 34 accumulates for each pixel 4 of the crystal array S a count of the counter values output by the second circuit (18, 20, 24, 26, 28, 30 and 32) for the pixel 4.
