- ArticleRenaud L, Joy ML, Gilday DL.J Nucl Med. 1979 Sep;20(9):986-91.We describe a new emission tomographic technique, using an Anger scintillation camera and a new family of coded apertures, in which a noniterative computer algorithm is used to reconstruct multiplanar images. The novel feature is a set of spatial narrow band filters that allow the depth information to be separated in the frequency domain. The position of the reconstructed planes can be selected at will. Using this technique, a planar resolution of 0.75 cm and a depth resolution of 1.6 cm have been measured at a depth of 10 cm and a magnification of 1. To demonstrate the potential of this system, the results of a phantom study are reported.
