Fig. 4From: Towards accurate partial volume correction in 99mTc oncology SPECT: perturbation for case-specific resolution estimationGraphs demonstrating the effect of lesion parameters of a lesion contrast and b lesion size on tangential FWHM measurements for selected reconstruction updates in noise-free images of the simple elliptical phantom. The point of measurement was in a lesion, 8Â cm from the centre of the FOVBack to article page
