Popis: The performances of standard gamma-cameras are limited by the well-known trade-off between spatial resolution and sensitivity resulting from the collimator. To overcome this limitation, we have previously proposed a new approach named HiSens, which consists in the association of a pixelated CZT detector, new collimation geometry and dedicated reconstruction algorithms. Two major characteristics of the CZT detector are taken advantage of in this architecture: the availability of the depth of interaction (DOI) information and the fine pixelization.
