The data corresponding to any single digital radio nuclide image can be described by a two-
dimensional matrix of random variables b:@, each representing the observed density of …

The general problems associated with multiple scan photon/X-ray transmission image
reconstruction are formulated and a technique which leads to a highly accurate solution is …

Most of the scan processing methods used to date are unable to distinguish between normal
and abnormal features. A method of constructing a particular orthogonal transform from a set …

An optimal data processor for detecting a small lesion (target) in a large organ (background)
is derived theoretically by maximizing the signal-to-noise (S/N) ratio. The highest S/N ratio is …

Until recently, data processing in nuclear medicine was understood to mean the use ofa
computer in scintigraphy with the aim of improving the image quality [1-8]. The spatial …

Several computer assisted processing and display methods are evaluated using a series of
100 normal brain scintigrams, 50 of which have had single'mathematical tumours' …
