Evaluation of attenuation rate error for optimisation of skin dosimeter in electron beam therapy

In the field of radiation therapy, the need for a flexible dosimeter that can be applied on the flexor surface for precise measurement of the surface dose is increasing. In particular, electron beam therapy has a shorter treatment depth than photon beam therapy; therefore, the surface dose must be measured accurately. This study investigates attenuation errors in a dosimeter. We demonstrated that the attenuation error depends on the thickness of...
