摘要： The present invention relates to a system and method for compensating for anode gain non-uniformity in a Multi-anode Position Sensitive Photomultiplier Tube (PS-PMT), in which a compensation unit is disposed between the multi-anode position sensitive photomultiplier tube and a position detection circuit unit and configured to uniform a current signal inputted to the position detection circuit unit, thereby compensating for anode gain non-uniformity. In accordance with the present invention, the compensation unit for changing resistance is used. Accordingly, there is an advantage in that the gain non-uniformity of each of the anodes of the PS-PMT can be compensated for. Furthermore, the gain non-uniformity of each of the anodes of the PS-PMT is compensated for by changing resistance values of the variable resistances of the compensation unit. Accordingly, there is an advantage in that the interaction positions of gamma rays can be calculated more precisely.

摘要： The present invention provides an apparatus for measuring a Depth-Of-Interaction (DOI), comprising a crystal layer 10 of a mono layer in which a plurality of crystals for absorbing gamma rays are consecutively arranged, scintillation light detectors disposed at one end of the crystals and configured to detect scintillation light emitted from the crystal layer 10 by the gamma rays, change means included in the crystals and configured to linearly change transmittance in a length direction of the crystals, and a control unit 30 configured to calculate the DOI in the crystal layer 10 on a basis of the first output signal and the second output signal. The scintillation light detector outputs the first output signal in one direction and the second output signal in a direction at a right angle to the one direction.
