MATERIALS AND METHODS Digital filters described in the literature have been designed to
work on a single image, ie, the filters are two-dimensional spatial filters (3— 15). Dynamic …

Two methods whereby a digital computer may be used to regulate a scintiscanning process
are discussed from the viewpoint of computer input-output software. The computer's function …

Lineprinter display of digital scintiscan data is becoming more common due to the wider

The ultimate performance test of an imaging system is its medical utility. This requires
clinical use and evaluation of how well the system improves the delivery of health care. The …

A possible method of carrying out dynamic, on-line deconvolution (or refocusing) of
scintigraphic data is outlined. Basically the method consists of taking each scintillation as it …

While it is not possible to specify in any general way how best to display clinical images, in
recent years significant progress has been made in understanding the factors which …
