Fig 6. 17 : Influence of centering on dose distribution at the lumen surface and at the reference depth. For reporting intraluminal brachytherapy with non-centred applicators minimum and maximum doses should be given for the reference depth and the lumen surface. A : Centered source with a symmetrical radial dose distribution. B : Non-centered source and its influence on the dose at the lumen surface and at the reference depth (modified from Pötter et al. 2001 (86)).
