Abstract
Pixellated detectors are a fast growing area of research. However performances of such detectors will be spoiled by the poor figures of conventional collimators. The computer aided collimation gamma camera (CACAO) is a new collimation possibility for emission tomography. The CACAO system uses large hole collimator aimed at increasing the sensitivity. This article studies the possible advantages of coupling the CACAO project with pixellated detectors. Simulations of images reconstruction seem to confirm the synergistic advantages of both techniques
