SBRT planning for liver metastases: A focus on immobilization, motion management and planning imaging techniques.
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.
