Resumo: | The dosimetry of the small and intensity modulated elds employed in radiotherapy, with high
dose gradients involved, is a quite demanding task. The need for reliable measurements in these
beams responds not only to quality assurance requirements, but also to the legal regulations of
Radiotherapy (in Spain, Real Decreto 1566/1998 sobre Criterios de Calidad en Radioterapia, and
also EURATOM 97/43). The complexity of modern radiotherapy techniques led to an extensive
incorporation of thorough treatment dosimetric veri cation in the hospital quality assurance
programs. This veri cation, previous to the treatment, is performed in order to check that the
dose distributions delivered by the radiotherapy machine match the corresponding planned dose
distributions within the required tolerances. One work performed in this thesis project consists
in the study of di erent commercial detector arrays, devices widely employed for dosimetric
treatment veri cation. The response of the detectors involved in these devices is determined in
order to study the impact of the detector size, technology and layout on the measurement of
intensity modulated dose distributions. The capabilities of detector arrays for the detection of
uence variations is also studied, as this is one of the main objectives of treatment veri cation. |
