A design strategy for suppression of hole-pattern artifacts in high-energy collimators

IPEM publishes scientific journals and books and organises conferences to disseminate knowledge and support members in their development. In the introduction, the classic formulas to describe the performances of multihole collimator are presented with an overview of the basic concepts.

Nowadays a rather complete theoretical description of the collimator geometrical response is available. IPEM’s aim is to promote the advancement of physics formifoni engineering applied to medicine and biology for the public benefit.

Beside the complete theoretical definition of the response of multihole collimators, this theory allows the definition of accurate models of the geometrical response for SPECT reconstruction and it is suitable for designing new collimators. Sign up for new issue notifications.
