Quality assurance in planning and implementing radiation therapy.

Quality Assurance (QA) programs in radiotherapy are based on an interdisciplinary team work with the participation of physicists and physicians in treatment decision-making and in the determination of accuracy in dosimetry. In this short article, quality control (QC) procedures for computer-assisted treatment planning and implementation, are reported. Particular attention is paid to the technological developments which could make QC programs feasible at Radiotherapy centers.
