Validation of GEANT4 for Accurate Modeling of $^{111}$In SPECT Acquisition

چکیده
Quantitative SPECT imaging of In is of growing importance in nuclear medicine applications like patient-specific radionuclide dosimetry. In this study, the quality of a Monte-Carlo based model of the imaging chain from nuclear decay to detection in a gamma camera is investigated. Important characteristics like the camera point spread function (PSF), the phantom attenuation and scatter effects are compared between simulation and experiment. The model shows a good agreement to the actual measurements and allows for further use in the development of quantitative SPECT reconstruction which will be mandatory for future oncology.

متن کاملValidation of Optimum ROI Size for 123I-FP-CIT SPECT Imaging Using a 3D Mathematical Cylinder Phantom
Objective(s): The partial volume effect (PVE) of single-photon emission computed tomography (SPECT) on corpus striatum imaging is caused by the underestimation of specific binding ratio (SBR). A large ROI (region of interest) set using the Southampton method is independent of PVE for SBR. The present study aimed to determine the optimal ROI size with contrast and SBR for striatum images and val...
