Optimization of conformal avoidance: A comparative study of prone vs. supine interstitial high-dose-rate breast brachytherapy

CT-based treatment planning allowed calculations of volumetric dose distribution to the target and all sensitive structures with proper visualization and volumetric delineation of organs of interest. The treatment plan shows significant dose reduction may be possible in various sensitive structures if the patient is treated with HDR brachytherapy in the prone position.
