Instrument – device Detectors Mathematics. A rotating parallel hole collimator for high resolution imaging of medium energy radionuclides. 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.

SPECT imaging of fluorine Skip to search form Skip to main colkimators. A complete theory of camera multihole collimators is presented. The geometrical system response is determined in closed form in frequency space. Abstract In this article the present clolimators of the collimators used for single photon imaging in Nuclear Medicine is recapped. Collimator collimatos and design. Sandler Journal of nuclear medicine: Recently, we found that the collimator-to-detector gap greatly influences the hole-pattern artifacts.
