Biography and Research Information
OverviewAI-generated summary
R.J. Megahed's research focuses on the application of radiation therapy for various cancer types, particularly in the head and neck region and thyroid. Recent publications investigate the utilization of postoperative radiation therapy for medullary thyroid cancer, spatial fractionation of radiation therapy for head and neck malignancies, and dosimetric variations in head and neck cancer patients undergoing intensity-modulated proton therapy. Megahed also studies liver-sparing total body irradiation for acute lymphoblastic leukemia and interstitial brachytherapy for soft tissue sarcomas. Collaborations include work with Gary D. Lewis, Santanu Samanta, Mausam Patel, and Mumtaz Patel, with whom Megahed has co-authored multiple publications. The researcher's work also explores the potential of dual-energy spectral CT parameters for assessing treatment response in head and neck cancer.
