With a medical degree and a specialization in radiation physics from the University of Florida, Dr. Alan H. Porter is a physician with extensive knowledge of radiation therapy and oncology. He has won several awards and is board certified by the American College of Radiology. Dr. Alan Porter primarily directs Porter Radiation Oncology, a center that gives patients access to various cancer treatment techniques including Tomotherapy, 3D Conformal Radiation Therapy, and Intensity-Modulated Radiation Therapy, or IMRT.

IMRT is an advanced form of radiation treatment for cancers and non-cancerous tumors. It delivers precise radiation doses based on the tumor's shape, which is perceived through computer-generated images. In IMRT, the intensity of the radiation is modulated to deliver extremely focused beams directly to the cancerous tissue, which decreases the amount of radiation used and, consequently, the collateral health issues it can create for the patient.

Typically, IMRT is employed to address tumors that are close to critical tissues and organs. It is often used to treat head and neck cancers, lung cancer, gastrointestinal cancer, gynecological cancers, lymphoma and sarcoma, among other conditions.
