The considerations of tissue response to radiation absorbed dose suggest a need for an accuracy of +/- 5% in its delivery. This is very demanding and its regular achievement requires careful quality control. There are three distinct phases to the delivery of the planned treatment: calibration of the radiation beam in a reference situation, calculation of the dose distribution for a patient relative to the reference dose and the delivery of the radiation to the patient as planned. Each has distinctly different quality assurance requirements and must be diligently observed if the desired accuracy is to be achieved.
对组织对辐射吸收剂量的反应的考量表明，在剂量传递方面需要达到±5%的精度。这要求非常苛刻，要经常达到这一精度需要仔细的质量控制。计划治疗的剂量传递有三个不同阶段：在参考情况下对辐射束进行校准、相对于参考剂量计算患者的剂量分布以及按计划向患者传递辐射。每个阶段都有截然不同的质量保证要求，若要达到所需精度，必须严格遵守。
