[The low-pass filtering of scintigraphic picture data in myocardial scintigraphy (author's transl)].

A digital Gauss-type filter is treated in consideration of low count dynamic myocardial scintigraphy. This filter type is favourable for several reasons. It is neutral in phase. An increase of signal-to-noise ratio in the scintigram is possible with tolerable loss of resolution. A nearly constant signal-to-noise ratio is available with a count controlled filtering. The estimation of the required count rate for a desired resolution is possible. The scintigraphic pulse height can be matched to the image processing system at all times. Fixed collimator dependent filter routines can be integrated into the image processing software.
