Single-photon emission tomography with a 12-pinhole collimator.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1982
To assess the advantages of more complete angular sampling and of more views in the tomographic reconstruction process, tomographic imaging with a 12-pinhole (12PH) collimator has been compared with 7-pinhole tomography (7PH). The 12PH system gives a 50% increase in sensitivity but resolution degrades more rapidly with depth.
