“…But it is known that some of the criticality for the electron dose calculation and/or dose deposition is induced by the presence of cavities and/or by irregular body shape. Mapping on of phantom-surface dose distributions is actually available both for rotational partial skin electron irradiation 39 and for general TSEB, 40,41 whereas in vivo dose variations with depth and body locations during TSEB are almost systematically reported in cited papers, but usually only for measurements with traditional TLD dosimeters. At any rate, dose uniformity remains difficult to reach, because of the varying curvature of body surface over the stray field 14,25,27 and some parts of the patient body can of course shield other parts.…”

“…The dose at 1 mm depth is likely to be the biologicallyrelevant dose because the depth of the dermis (from where fibroblasts are primarily being analyzed) is approximately 0.1 to 1.5 mm from the surface [14,18,24,30,41]. Furthermore, a depth of 1-2 mm has been reported in the literature as relevant for skin irradiation [19,37]. Consequently we have used the dose at 1 mm depth for our further analyses.…”

“…Physical conditions for large area electron treatment have been described in literature. [11][12][13] Techniques to produce large electron fields include the superposition of two fields at two gantry angles, [11][12][13][14][15][16] matching multiple fields, 3,17 producing single large fields with a special beam flattening filter, 18 using multiple rotational arc fields 19 or by movement of the patient through a shorter field on a translation couch. 20 Treating the complete circumference of the patient is achieved by either irradiating the patient with static fields from various directions (which requires different positioning of the patient for each field) 11,12,16 or by rotating the patient in the beam.…”
