Abstract
Transmission attenuation correction device for scintigraphic cameras that contain a source of gamma rays that sweep the active surface of a detector facing it through the body of the patient in order to measure the attenuation of the photon energy through this body and therefore allow for the correction of the attenuation of the photon energy emitted by the radiated organ. The radioactive source (,) is inserted in a rod (,) located in a removable cassette (,), this rod can automatically isolate the source (,) when the cassette (,) is not in its support. Each device is contained in a box attached to the detector other than the one facing it. The rod (,) that contains the source has different realization forms that make it possible to include materials that each have their own attenuation coefficient.
