| Research Abstract |
Positron emission tomography (PET) is a powerful tool in the diagnosis and early detection of cancer. The depth-of-interaction (DOI) detector which provides a radiation detected location 3-dimensionally plays an important role for a PET scanner to have an accurate image. In this study, I developed a DOI detector having high position resolution by a new standpoint, that is, changing the shape of detector crystals. With this method I could attain the position resolution of 8 divisions in the DOI detector whereas other research groups attained the resolutions of 2 or 3 divisions. The method can be also applied to any kind of detector crystals.
