Abstract

Two ways of measuring the performance of the display system of a clinical radioisotope imaging device are considered: (i) using the method of constant stimuli; and (ii) using signal detection theory. The adjustment of a rectilinear scanner with multicolour, equal bandwidth, linear ribbon for better abnormality detection is discussed. A comparison was made between setting the maximum counts at the edge and at the middle of a colour band using the two methods. It was found that setting up the maximum counts at the middle of the band rather than at the edge favours easy detection by both methods independently.
