Abstract
To acquire both a scatter image and an emission image in nuclear medicine, it is chosen to detect the emission image by validating the radioactive events that occur in the nominal range of the radioactive marker chosen. For the scatter image, lower energy ranges are chosen, these ranges corresponding to the production of at least secondary or tertiary Compton photons. It is shown that it is possible, in this way, to reconstruct an artifact-free transmission image. This scatter image is used to correct the initially acquired emission image. It is shown that it is possible to acquire both images at the same time.
