The application of different imaging techniques in the planning of and during radiation therapy enables a precise definition of the target region and healthy tissue. New three-dimensional radiotherapy techniques and advanced radiation equipment enable precise implementation of the desired dose of radiation to the treatment region. By using different imaging techniques, a higher treatment dose to the tumor region is enabled with simultaneous protection of healthy tissue structures. The likelihood of mistakes between the treatment plan and its implementation can also be reduced. Accordingly, the aim of image guided radiation therapy is to improve treatment results and at the same time reduce treatment-related side effects.
不同成像技术在放射治疗计划制定及治疗过程中的应用，能够精确界定靶区和健康组织。新的三维放射治疗技术及先进的放射设备可使向治疗区域精确施加所需辐射剂量成为可能。通过使用不同成像技术，在保护健康组织结构的同时，能够提高肿瘤区域的治疗剂量。治疗计划与其实施之间出现错误的可能性也能降低。因此，图像引导放射治疗的目的是改善治疗效果，同时减少与治疗相关的副作用。
