Abstract

A digital brain phantom was created from 3D CAD images and imported to a simulation of a Siemens Healthineers Symbia Evo SPECT system. The simulation was performed using GATE, a Geant-4 based Monte Carlo toolkit, which included features to import 3D CAD structures. The brain object was generated using an MRI study of a human brain and imported to GATE as a tessellated mesh filled with radiation infused water that had a radiation spectrum matching Tc-99m and spatial distribution that filled the brain volume. The simulation was configured for a dual head SPECT with a LEHR parallel collimator and NaI scintillation detectors on a brain phantom filled with water. The resulting projection.
