内容記述 | 1.Introduction Positron emission tomography (PET) plays important roles in cancer diagnosis and molecular imaging research; but potential points remain for which big improvements could be made, including resolution, sensitivity and costs. Therefore, research on next generation PET technologies remains a hot topic worldwide. The Biophysics Program [1] in National Institute of Radiological Sciences (NIRS) [2] carries out basic studies on instrumentation, image reconstruction and data corrections to improve image quality and quantity in nuclear medicine. A depth-of-interaction (DOI) detector will be a key device to get any significant improvement in sensitivity while maintaining high spatial resolution [3-5]. DOI measurement also has a potential to expand PET application fields because it allows for more flexible detector arrangement. As an example, we are developing the world's first, open-type PET geometry "OpenPET", which is expected to lead to PET imaging during treatment [6]. We have developed a small prototype to show a proof-of-concept of OpenPET imaging [7]. The DOI detector itself continues to evolve with the help of recently developed semiconductor photodetectors, often referred to as silicon photomultipliers (SiPMs). We are developing a SiPM-based DOI detector "X'tal cube" to achieve sub-mm spatial resolution, which is reaching the theoretical limitation of PET imaging. We have developed a prototype of 1mm isotropic detector resolution, which equals the world record [8]. \n2.Research topics Open-type PET "OpenPET" and its applications Next generation DOI detector "X'tal cube" Integrated PET/MRI system Feasibility study of an extendable, entire body PET Real-time tumor tracking by the OpenPET Real-time dose distribution monitoring system in interventional radiology PET attenuation correction methods based on MR images Quantification methods for PET data |
