Abstract

The six-field total skin electron irradiation (TSEI) technique needs an accurate preliminary dosimetric study. The American Association Physics in Medicine (AAPM) defined a dosimetric protocol that recommends the careful dosimetry of the horizontal, the dual and the six-dual fields by using both a cubic and a cylindrical phantoms. In our Institute, in a TSEI development program, we carried out the preliminary dosimetry according to AAPM criteria. We also investigated some dosimetric problems--e.g., the so-called "cable effect", which takes place when the detector cable in a TSEI field is not well shielded, polarity effects and photon contamination. As to the "cable effect", it is especially marked with the Markus NE2534 chamber; moreover, this effect, if not considered, can lead to overestimation of X-rays contamination.
