Abstract: PURPOSE: An apparatus and a method for measuring an interaction depth and a positron emitting scanner using the same are provided to obtain continuous information related to the interaction depth. CONSTITUTION: A single crystal layer(10) includes a plurality of crystals absorbing gamma-ray which is adjacently and continuously arranged. A flash detector is installed to one end of the crystals in order to detect flash generated from the crystal layer due to the gamma-ray. A changing unit changes the transmittance of the crystals. The flash detector outputs a first outputting signal and a second outputting signal. A controlling unit(30) calculates the interaction depth of the crystal layer based on the outputting signals.

Abstract: PURPOSE: A system and a method for compensating non-uniformity of a gain of a location sensitivity type multi-anode photomultiplier tube are provided to compensate the non-uniformity of the gain in each anode of the location sensitivity type multi-anode photomultiplier tub by introducing a compensation unit for changing a resistance. CONSTITUTION: A location sensitivity type multi-anode photomultiplier(200) converts a scintillation of an incident gamma ray in a predetermined scintillation crystal(100) to electrons and amplifies a current signal according to each of a plurality of channels. A location detection circuit unit(300) divides the amplified current signal into four current signals to represent a detected location of the gamma ray on the scintillation crystal on the basis of the amplified current signal to the two-dimensional energy distribution. A compensation unit(400) compensates the intensity of the current signal inputted into the location detection circuit unit by changing at least one of a serial variable resistance and a parallel variable resistance. A coordinate production unit(500) receives the four current signals and produces the coordinates of the detected location of the gamma ray on the basis of the current signal having the compensated intensity.
