Accurate and precise TOF-PET brain imaging despite inevitable system modelling errors KU Leuven
Positron emission tomography (PET) is a molecular imaging technique. A tracer molecule labeled with a positron emitter is administered to the patient. Upon decay, the positron annihilates with an electron and two photons are emitted back to back. When both photons are detected, we know that there is a tracer molecule somewhere along the line between the two detector elements. From a set of such PET measurements a tracer concentration image is ...
