Design and performance evaluation of a new high energy parallel hole formioni for radioiodine planar imaging by gamma cameras: Citations Publications citing this paper. Difficulties and some new perspectives on avoiding both penetration and hole pattern artifacts while designing high-energy collimators are mentioned. IPEM publishes scientific journals and books and organises conferences to disseminate knowledge and support members in their development.

Topics Discussed in This Paper.

In addition, we also showed that specific values of the gap exist which minimize the artifacts: Abstract In this article the present knowledge of the collimators used for single photon imaging in Nuclear Medicine is recapped. Skip to search form Skip to main content.


In section Collimator sr 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.

This closed form accounts for the known efficiency and resolution formulae for parallel beam, fan beam, cone beam and astigmatic collimators as well as for the most frequent hole array patterns and hole shapes. Instrument – device Detectors Mathematics.
