CyberKnife treatment plan of a 226 cc metastasis in the upper liver overlaid on contrast enhanced T1-weighted MRI in axial (upper right), sagittal (lower left), and coronal (lower right) view. The prescription dose to the planning target volume was lowered to 3 × 12 Gy (BED10 = 79.2 Gy10) to the 60 % isodose due to the size and critical organ constraints (i.e., the heart). The mean gross tumor volume dose was optimized to 140 Gy10. Twenty-eight months after treatment, the patient was alive and had complete response with no further development of metastases in the meantime.
