    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 Diagram illustrating the imaging of two spherical 5mm diameter breast tumours in craniocaudalview with a dual-head Compton camera Challenging imaging scenarios for breast lesions (5 mm) located close to the chest wall for 18F (511 keV) Diagram illustrating the imaging of two spherical brain tumours of 5mm diameter filled with 113mIn and 18F radiotracers The reconstructed images of the brain lesions (5 mm) filled with18F (left) and 113mIn (right) radiotracers Conclusion
