“…CZT detector applications occur in a wide range of areas: medicine (associated with imaging techniques such as x-ray or gamma ray tomography, x-ray fluorescence, x-ray simultaneous dual-energy), space technology (high energy focus telescope-HEFT) and security (monitoring of radioactive materials in nuclear plants) and others such as the use of CZT detector for the non-destructive examination of art objects in museums and archaeological sites, by Schlesinger et al (2001), Diéguez (2011), McGregor (1997 and Schlesinger et al (1995). These materials are grown in UNIDEF-MINDEF, Martínez (2012).…”

“…where k is the material density, which is 5.83 g cc −1 for CZT ( [31]), and G is the photoelectric absorption coefficient, for an incident photon energy E of approximately 218 keV, G is approximately 0.246 cc g −1 , a thickness of absorber larger than 13.2 mm can stop 85% photons. With an absorber thickness equal to 10 mm, as simulated in this study, approximately 76% of photons at 218 keV can be stopped and fully absorbed.…”

In this study, we introduce a collimator less SPECT system for dynamic whole-body imaging, which enables multienergy gamma photon detection with higher efficiency compared to mechanically collimated SPECT. The system consists of two detectors, one movable and one fixed, providing a field of view (FOV) adequate for whole-body imaging, while achieving high sensitivity and clinically usable imaging resolution within a reasonable scanning time. This work focuses on the system design using the Monte Carlo simulation toolkit Gate 9.2. The imaging performance is evaluated at two energy peaks (440 keV, 218 keV), representing the major detectable gamma energies generated from Actinium-225, one of the radionuclides under investigation for targeted alpha therapy (TAT). We intend to use the collimator-less system for treatment response monitoring in TAT. Results demonstrate a system resolution of 1.0 cm with a sensitivity of 0.50% for whole-body imaging as measured using a Derenzo-type phantom in the simulation. This demonstrates that the proposed system may serve as an alternative imaging tool for rapid scanning in clinical settings.
