Improved Techniques for PET Imaging

Résumé

Positron Emission Tomography (PET) is a medical imaging technique based on the administration of molecules of biological interest labelled with a radionuclide which decays + emitting positrons. These positrons are annihilated with an electron emitting, most of the times, two photons, in opposite directions which are detected in coincidence in as canner (usually with detectors arranged in a ring form). Then the position of the source inside the body can be determined from the directions given by the two detection points of each coincidence, reconstructing the image of the uptake of the radio-labelled drug in the organism. These images provides important functional information of the body of the patient...
