References Publications referenced by this paper. 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.

Difficulties and some new perspectives on avoiding both penetration and hole pattern artifacts while designing collimstors collimators are mentioned.

Koral Journal of nuclear medicine: In addition, we also showed that specific values of the gap exist which minimize the artifacts: Sandler Journal of nuclear medicine: Collimator characteristics and design. Recently, we found that the collimator-to-detector gap greatly influences the hole-pattern artifacts.
