放射治疗的初步目标是递送符合目标的放射剂量，同时使对周围正常组织的剂量最小化。多叶准直器（MLC）调强放射治疗（IMRT）是实现适形放射治疗的一种有前途的方法。配备IMRT系统的医用直线加速器（linac）可以增加靶区剂量，减少正常组织剂量。这些能力可以通过剂量优化技术显著增强。IMRT集成了快速发展的成像、计算机、优化和治疗输送技术。由此产生的系统从根本上将其自身与现有技术区分开来。因此，需要新的质量保证（QA）程序。
A preliminary goal of radiation therapy is to deliver radiation doses that conform to targets, while minimizing dose to surrounding normal tissue. Intensity-modulated radiation therapy (IMRT) delivered with a multileaf collimator (MLC) is a promising resource to achieve conformal therapy. A medical linear accelerator (linac) equipped with an IMRT system can increase dose to the target and decrease dose to normal tissue. These capabilities may be significantly enhanced with dose optimization techniques. IMRT integrates rapidly evolving imaging, computer, optimization, and treatment delivery technologies. Resulting systems fundamentally distinguish themselves from prior technology. Thus, new quality assurance (QA) procedures are needed.
