In this work we report on GATE simulation studies of DC-SPECT, a body contouring system designed for cardiac imaging applications. The design concept of the DC-SPECT is based on multiple simultaneous view of the heart enabled by the use of laser processed CsI:Tl detector modules with high intrinsic detector resolution. Our theoretical and GATE simulation results show that we can obtain ∼0.081% system...
Laser Induced Optical Barriers (LIOB) is a promising technique for fabrication of high resolution and high sensitivity scintillator detectors for Positron Emission Tomography (PET). With LIOB local changes in refractive index may be introduced inside the bulk of a monolithic crystal by using a tightly focused pulsed laser. One major advantage of LIOB compared to standard mechanical pixelation techniques...
By utilizing finely pitched scintillator arrays where the scintillator has high atomic number and density, fast decay time, and high light output, realizing a scintillator-based Photon Counting Detector (PCD) is conceptually feasible. Fabrication of fine-pitched scintillator arrays however, has been the bottleneck for realizing such detectors. Combining the novel scintillator fabrication technique...
Current high-resolution scintillators are fabricated using mechanical pixelation technique. However the fabrication cost of finely pitched scintillator arrays together with their lack of flexibility to accommodate new depth of interaction designs has remained a significant issue with mechanical pixelation. Another pitfall of mechanically pixelated scintillators is their relatively large inter-pixel...
