Abstract
To acquire measurement data elements during a tomography type experiment in nuclear medecine, with a gamma camera having two detector heads, each of these heads is oriented on a sighting center P while the set of two heads rotates about a center of rotation Ia of the apparatus, the center of rotation being offset from the sighting center. It is shown that this approach provides speedier operation for the acquisition and also contributes to the preparation of tomography images that are more precise and more easily computed.
