SIMULTANEOUS ACQUISITION OF TRANSMITTED SHOTS AND EMITTED SHOTS FOR A GAMMA CAMERA

摘要

P The invention relates to a method of simultaneous acquisition of a transmission image and of an emission image with a gamma camera provided with a detector (3), the detector (3) being facing a patient. (5) in which a first radioactive isotope emitting gamma photons (gamma2) has been injected into a first energy range (P1), said method comprising the steps of moving a radioactive source (4) behind the patient (5 ), said source (4) being composed of a second isotope emitting gamma photons (gamma1) in a second energy (P2) and production range, upon detection of an impact of a gamma photon on the detector (3), coordinates of the impact of the photon on the detector and information relating to the energy of the photon during the impact, said method having the particularity of differentiating the impacts of photons according to their energy level and impact position relative to position d e source (4). /P
