Pinhole SPECT for imaging in-111 in the head


Conference Paper

Simulation and experimental phantom studies have been used to investigate pinhole SPECT for imaging In-111 in the head. Chang attenuation and dual window scatter subtraction compensation methods have been evaluated for potential accuracy in pinhole geometry. Results have shown improved image quality with pinhole collimation with a ≤15% quantitative accuracy in phantom studies. Therefore, pinhole SPECT is demonstrated to be a viable alternative to medium energy collimator imaging of In-111 in objects the size of the head.
