Evaluation of a multi-atlas CT synthesis approach for MRI-only radiotherapy treatment planning

Highlights • Establishing MRI-only RTP workflows requires synthetic CTs for dose calculation.• This study evaluates the feasibility of using a multi-atlas CT synthesis approach.• The proposed method was validated on head and neck and prostate cancer patients.• Results showed an accurate bone estimation for future patient positioning.• Results showed that synthetic CTs are suitable to perform clinical dose calculations.
