Intensity-modulated radiation therapy (IMRT) requires the use of inverse treatment planning and nonuniform fluence beams delivered by a series of complex radiation portals. The quality assurance procedures for conventional three-dimensional conformal radiation therapy (3D-CRT) have been developed and are in worldwide clinical use, but the more complex nature of IMRT limits the application of much of the quality assurance (QA) procedures developed for IMRT. Although consensus has not yet been… CONTINUE READING
