| Outline of Final Research Achievements |
We apply quantum entanglement to correct for scattering loses in Positron Emission Tomography (PET). We have reformulated Compton scattering of entangled photons in terms Stoke’s matrices, making it easier to understand the underlying scattering dynamics, and we found structures in the cross-section which are solely due to entanglement.
We found a particular Compton scattering configuration to find the scattering sites, which we call “the touch cone configuration”. This idea is under a provisional patent and will be applied in future work. We have also included atomic electron binding effects as well, which will make future GEANT4 simulations reflect more accurately the scattering processes in biological material.
The significance of locating scattering sites paves the way for the development of a single modality machine which combines the analytical reach of a PET and CT scanner resulting in reduced radiation exposure to the patient, as well as correcting for attenuation.
