Heart Position and Radiation Dose in Actual Treatment
heart D
A total of 98 CBCT images were uploaded to the planning system and registered with the planning CTs based on the breast target. The average dice similarity coefficient of heart contour from CBCT and DIBH-planned was 0.98 (0.92-0.98), indicating high consistency of heart position between simulation positioning and actual RT implementation.
