In order to measure the position of the scintillation pixel of the positron emission tomography (PET) detector module, it is necessary to obtain a flood image through a radiation source and then perform a segmentation process of each scintillation pixel area in the flood image. Without performing this process, a method of reading the scintillation pixel position using simulation data was developed. It was difficult to directly apply the data obtained through simulation to the experimental data since simulation data and experimental data cannot be directly matched. In this study, the Anger data of four channels obtained from the detector module composed of simulation were calculated at the ratio according to the channel and applied to the experimental data. Through simulation, a look-up table (LUT) for each scintillation pixel was prepared, and the position of the scintillation pixel where the gamma ray event occurred was measured using the experimental data and the maximum likelihood position estimation (MLPE). The measurement result showed an accuracy of 94.4 %. If these study results are introduced into the PET detector module, the position of the scintillation pixel can be read quickly and conveniently without changing the existing system.
