In the last decade, technological improvements in radiotherapy have been significant and consequently the use and importance of radiotherapy in cancer treatment have increased greatly. A fundamental advance has been the development of external beam techniques aimed at dose deliveries that are highly localized on the tumour volume, sparing at the same time most of the surrounding healthy tissues. These techniques include conformal radiotherapy as well as intensity-modulated radiotherapy (IMRT). However, these methodological improvements require corresponding improvements in the dosimetry methods, in order to ensure that the values calculated with computer treatment planning systems, adopted in the clinical praxis, agree with the delivered dose distributions.
