Abstract
Nuclear Medicine Imaging System –Gamma camera
Gamma camera head
Compton camera
Compton scattering (what you were taught)
Compton scattering (what really happens)
Doppler Broadening
How Doppler broadening affects the electron energy spectrum at 𝜽𝜽=90°
Image degradation (FWHM) due to Doppler broadening for the selected materials
Theoretical efficiencies with respect to Compton scattering for selected materials
Efficiency evaluation of the two detectors across experimental thickness at 140.5 keV
Preliminary findings
Pre-clinical evaluations
