Partial bolussing to improve the depth doses in the surface region of low energy electron beams.
In many low energy electron beams the surface dose is considerably less than the maximum dose, making them unsatisfactory for clinical application. A method is described for producing better surface dose uniformity in such beams. The method makes use of bolus applied to the patient for a fraction of each daily electron treatment. The technique is shown to be simple and practical. This approach is compared to more conventional techniques of using bolus in electron beams.
