For in-beam positron emission tomography (PET), which is an in situ monitoring method for charged particle therapy, we developed the world’s first open-type PET system “OpenPET.” Following our previous studies for small prototypes, in this paper, we finally developed a whole-body dual ring OpenPET (WBDROP). This scanner has two separated rings. Each ring has two detector rings of 40 detector blocks,...
One of the challenging applications of PET is implementing it for in-beam PET, which is an in situ monitoring method for charged particle therapy. For this purpose, we have previously proposed two geometries for our original open-type PET scanners named OpenPET. Following our initial proposal of the dual-ring OpenPET (DROP) in 2008, we developed a whole-body prototype of DROP (WBDROP) in 2014 to show...
Depth-of-interaction (DOI) measurement is essential for PET to reduce the parallax error, which results in improved spatial resolution while maintaining the sensitivity. One of the ultimate goals for improvement of DOI detectors is achieving their isotopic spatial resolution. For this purpose, we have developed an isotropic 3D position-sensitive PET detector named the X'tal cube detector. The X'tal...
