Modeling dose to normal brain following hypofractionated stereotactic radiotherapy to a single brain metastasis.

Key Points

• This research aims to develop predictive models for low dose distribution in brain radiotherapy.
• Developed three predictive models for low dose to normal brain.
• Explored a comprehensive range of variables affecting dose distribution.
• Applied VMAT technique with 6MV plans for brain metastasis.
• Identified quantifiable low dose limits achievable to normal brain.
• Demonstrated the impact of various factors on dose delivery.
• Established models that are among the first of their kind in this research area.
