Helvecio Mota, PhD


        Dr. Mota specializes in biophysics and medical physics at the ECU Physicians Radiation Oncology Department at East Carolina University's Brody School of Medicine. Since joining the department in 2003, Dr. Mota has used the latest technology in clinical therapy physics and has pursued opportunities to improve knowledge in the field. A key member of the radiation therapy team at PCMH, he is an active researcher in dosimetry, image-guided radiation therapy (IMRT) and intensity modulated radiation therapy (IGRT). A clinical associate professor at East Carolina University, Dr. Mota teaches in the Medical Physics graduate program.
        In addition to his many responsibilities as researcher, educator and technician, Dr. Mota is active internationally and has organized several international courses and scientific meetings. He is a consultant in the area of radiation protection for international organizations such as the World Health Organization/PAHO and the International Atomic Energy Agency.

Gamma Knife Experience
        Dr. Mota received his Gamma Knife stereotactic surgery certification from the University of Pittsburgh. He is an authorized by the NC Nuclear and Radiation Safety Authority as a medical physicist for the Gamma Knife at PCMH.
