We have developed an electron-tracking Compton camera (ETCC) for new imaging reagents study. Energy limitation of gamma camera is major problem for this study. However, our ETCC has a wide energy dynamic range (200-1300 keV). In this paper, we show the results of imaging reagent study as follows: (1) F-18-FDG (511 keV) and I-131-MIBG (364 keV) simultaneous imaging for double clinical tracer imaging,...
Compton Camera has a potential for nuclear medicine. Because energy dynamic range and field of view is wide. Electron Tracking Compton Camera (ETCC) which we have developed consists of two detectors micro Time Projection Chamber (μTPC) and Pixel Scintillator Array (PSA). We have developed two type of ETCC small and large, and we have evaluated these cameras and have imaged phantom and small animal.
We have developed the Electron tracking Compton Camera (ETCC) with reconstructing the 3-D tracks of the scattered electron in Compton process for both gamma-ray astronomy and medical imaging [1–3]. By measuring both the directions and energies of a recoil gamma ray and a scattered electron, the direction of the incident gamma ray is determined for an individual photon. Furthermore, a residual measured...
