External radiotherapy dosimetry in nonstandard fields

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...
