The impact of semilateral decubitus position on the dose-volume parameters of the heart and lung for left sided breast cancer patients: A comparative dosimetric study

Treatment plans for patients in the SLD position with or without breath hold for left-sided breast cancer patients demonstrated a superior heart and lung sparing compared with the supine position due to significant reduction in MHD and CLD. MHD and CLD are important simulation factors that affect the heart and lung DVP.
