  • Title: [Dosimetry on a rotating phantom in remote electron irradiation].
    Author: Müller-Sievers K, Schäffler D, Kober B, Wöllgens P.
    Journal: Strahlenther Onkol; 1988 Aug; 164(8):484-8. PubMed ID: 3138768.
    Abstract:
    The Therac-20 Saturne produces a high dose rate electron radiation allowing a whole-skin electron irradiation. The problem of producing large fields enclosing the whole patient has been solved by superposition of two tilted stationary fields. The angle regulations are optimized by a computer program fed with the TLD values of transverse dose distributions. A homogeneous irradiation is obtained by the patient's rotation on a turntable within the radiation field. In case of a distance of 3 m between focus and skin, the irradiation times are only 5 min for a body surface dose of 1 Gy.
