GTM operating point characteristics showing fractional error (FE) in GTM correction factor per millimeter of PSF w-error in the vicinity of our operating point (w = w0 = 5 mm) plotted as a function of GTM SUVR correction factor (CSUVR). Each point in a plot derives from an individual subject. The blue points show the SUVR fractional error (FESUVR) and the line is a best fit. The black circles show the cerebellum fractional error (FECer) and illustrate the (negative) contribution of the cerebellum to the fractional SUVR error. Both fractional errors are presented as a function of the regional SUVR correction factor. Thus, there are corresponding black and blue points at each CSUVR value
