Homeland security applications demand high performance Compton-camera systems, with high detector efficiency, good nuclide identification and able to operate in-field conditions. A low-Z scintillator has been proposed and studied as a promising candidate for use in the scattering plane of a scintillator-based Compton camera: CaF 2 (Eu). All the relevant properties for the application of this scintillator in a mobile Compton camera system have been addressed: the energy resolution and the non-linearity at room temperature and in the temperature range of -20°C to +55°C, the photoelectron yield and the relative light yield in the relevant temperature range. A new method of inferring the relative light output of scintillators as a function of temperature has been proposed.

Therefore, it is obvious to use a Compton camera for applications in astronomy [1], homeland security [2] and medical imaging [3] if wide energy range photons have to be measured. A particular application of a Compton camera in medical imaging can be the monitoring of ion radiation therapy.…”

“…The operating principle of the Compton camera, also called electronical collimation, enables it to detect considerably more photons than a mechanically collimated system. Already used in astronomy [5] the Compton camera may be used for homeland security [6] and is a good candidate for the monitoring of ion beam therapy [7], [8].…”

The Compton camera is an imaging device rel evant for the detection of prompt photons produced during nuclear fragmentation in hadrontherapy. It allows a considerable improvement in detection compared to a standard gamma camera but also requires more sophisticated image reconstruction techniques. In this work we apply a recently developed filtered backprojection algorithm to data simulated from a realistic Compton camera prototype designed for hadron therapy on-line monitoring. We reconstruct images of a point source having a broad energy spectrum compatible with the up-mentioned application. Preliminary results indicate that the achievable resolution in directions parallel to the camera, thus including the beam direction, are compatible with the quality control requirements. With the prototype under study, the reconstructed image is elongated in the direction orthogonal to the camera.However this direction is of less interest and the resolution may be easily recovered using a second camera.
