FWHM measurements in each direction vs reconstruction update number (10 updates = 1 full iteration) measured in a central lesion without noise, b off-centre lesion without noise, c central lesion with noise and d off-centre lesion with noise. The perturbation point was positioned in the centre of a 36 mm radius lesion and the lesion TBR was 10 in all cases shown. Error bars relate to the standard deviation in the fitted FWHM parameters but are too small to be seen clearly on noise-free data
