Aim: To evaluate the different techniques used for liver metastases Stereotactic Body Radiation Therapy (SBRT) planning. We especially focused on immobilization devices, motion management and imaging used for contouring.
Background: Although some guidelines exist, there is no consensus regarding the minimal requirements for liver SBRT treatments.
Materials and methods: We reviewed the main liver metastases SBRT publications and guidelines; and compared the techniques used for immobilization, motion management, margins and imaging.
Results: There is a wide variety of techniques used for immobilization, motion management and planning imaging.
Conclusions: We provide a subjective critical analysis of minimal requirements and ideal technique for liver SBRT planning.
