Research Abstract

Positron emission tomography (PET) is a method to image distribution of substance in a body and often used in medical field. For example, specific accumulations observed in an image of glucose distribution indicate exist of tumors. Such PET image is obtained by injecting radioisotope (RI) of the substance and detecting the radiations from the RI at outside the body so that the image quality is much depends on performance of the radiation detectors. Our research team was developed the high performance PET detector which could be realized by recent popularization of small photo-detector devices. In this study, it was proved that, aiming for gaining the detector sensitivity, extension of the detector volume in one direction (a long shape) was possible with maintaining detector spatial resolution. Also, it was found that the new trials in fabrication, the use of plate scintillators for high yield rate and laser processing, were effective.
