Abstract
The invention relates to a method for quality assurance of a radiation field () emitted by a radiation therapy apparatus (), comprising the steps of: (i) providing an ionization chamber () detector as reference detector for measuring the dose of the radiation field () at the exit of the radiation head (), said ionization chamber () having a size and being positioned for being traversed by said radiation beam (), said ionization chamber () having an attenuation equivalent to less than 1 mm Al; (ii) providing one or more field detectors (); moving the field detector () across the radiation field () and measuring simultaneously the dose from the field detector () and from the ionization chamber (); (iii) computing the ratio of the dose from the field detector () to the dose of the ionization chamber (). The invention also relates to a device for performing the method.
