Description

It was the aim of the study described here to evaluate the quality of images obtained by SPECT on the basis of a set of different system parameters. The parameters chosen for this purpose were: 1) the influence of camera homogeneities on the quality of tomograms; 2) the relationship between the counting rate for the projected images and the counting rate equivalent (grey scale value) subsequently seen in the tomogrammes; 3) the way in which the centre of the image matrix is brought into the focus of the rotation centre. The results are described and discussed. (orig./MG)

Abstract (German)

Ziel der vorliegenden Arbeit ist eine Untersuchung der Qualitaet der SPECT in Abhaengigkeit von verschiedenen Systemparametern. Folgende Parameter wurden untersucht: 1) Der Einfluss der Kamerahomogenitaeten auf die Qualitaet der Tomogramme, 2) die Beziehung zwischen der Zaehlrate in den Projektionen und dem resultierenden Zaehlratenaequivalent (Grauwert) in den Tomogrammen und 3) die Einstellung des Zentrums der Bildmatrix auf das Rotationszentrum. Die Ergebnisse werden dargestellt und diskutiert. (orig./MG)
