The high spatial and energy resolutions of the Voxel Imaging PET detector developed at IFAE enables the way to construct a large Field Of View (FOV) Compton Gamma Camera at room temperature.

- By combining the PET design with Compton Camera to form Compton-PET scanner, one can obtain a novel device that provide PET images without image reconstruction. The VIP Compton-PET scanner can provide a real time map for PET isotopes concentrations in the object being diagnosed. This is possible when the isotope emits an extra gamma photon along with the e+ , such as in 44Sc where an additional gamma of 1157 keV is emitted. Preliminary tests, using 3mm point source of 22Na, shows an image of the source with FWHM of 3mm without the use of any image reconstruction algorithm. The spatial resolution is equivalent of TOF of 10 ps
- Each sensing device is arranged and connected on top of each other, avoiding gaps between devices, ensuring a high voltage to polarize each device’s detector, configuration that reduces the parasitic capacitance (noise), then enabling high image resolution performance and providing 2 detection planes for Compton imaging applications.
- The scanning module configuration - consisting on several sensing devices disposed in a staggered manner - also increases the image precision by an exact gamma-ray impact location determination, facilitating image-guided interventions.
- A novel Compton camera design based on a front / rear detection configuration generates a large field of view. Several semiconductors are disposed in the same substrate in such a manner that the scattered acts as front detector and the photon absorption system as rear detector.
