intensity-modulated radiation therapy (IMRT) to treat head-and-neck cancer focusing on the …

Many head‐and‐neck cancer (HNC) patients treated with radiotherapy suffer significant
anatomical changes due to tumor shrinkage or weight loss. The purpose of this study was to …

Purpose. Evaluating a method for anatomic changes assessment and actually delivered
doses during head and neck (H&N) cancer radiotherapy (RT) utilizing volumetric images …

PURPOSE: Anatomic changes and positional variability during intensity-modulated radiation
therapy (IMRT) for head and neck cancer can lead to clinically significant dosimetric …
