| 内容記述 | We are developing a new PET system integrated with an RF-coil of an MRI using four-layer depth-of-interaction (DOI) detectors. In the proposed system, PET detectors which consist of a scintillator block, photo sensors and front-end circuits are placed close to the objective. Elements of the RF coil are inserted between gaps of the scintillation crystal block. Therefore the proposed system realizes high spatial resolution and sensitivity for the PET scanner by using the four-layer DOI detector. We constructed a prototype four-layer DOI-PET detector mounted on a prototype RF-coil for PET-MRI and carried out experiments in an actual MRI system to investigated influences on the PET detector and the MRI system from each other. As a result, sufficient detector performance of the DOI-PET detector regarding crystal identification and energy resolution was achieved in simultaneous measurements. The MRI images were also obtained as usual even though the DOI-PET detector was positioned close to the RF coil elements. | |||||
