The rotational total skin electron irradiation technique at the McGill University Health Centre has undergone several developments over the past few years. Replacement of the formerly used linear accelerator has prompted many modifications to the previously reported technique. With the current technique, the patient is treated while standing on a rotating platform, with a single large field at a source to surface distance of 378 cm. The electron field is produced by a Varian 21EX linear accelerator using the commercially developed 6 MeV high dose rate total skin electron mode, along with a custom-built flattening filter. Ionization chambers, radiochromic film, and MOSFET detectors have all been used to confirm the dosimetric properties of this technique. Measurements investigating the stationary beam properties, the effects of full rotation, and the dose distributions to a humanoid phantom are reported. In addition, comparisons with commonly-used stationary beam treatment alternatives are presented.
