Advanced Radiation Treatment with Imaging Technology

How Image-Guided Radiation Therapy (IGRT) Works

Along with IMRT, IGRT is an advanced  type of cancer radiation therapy offered at Coastal Radiation Oncology Cancer Treatment Centers that uses 2D, 3D, and 4D imaging technology (the fourth dimension being images taken in real time) to pinpoint the precise shape and location of a cancerous tumor and accurately deliver radiation beams to its location.

Using special imaging technology, IGRT allows Coastal physicians and treatment specialists to view or “image” a tumor before, during, and after treatment. By imaging the tumor prior to the delivery of each radiation treatment, miniscule adjustments can be made to the radiation beams to precisely target the tumor, which may move or change shape and size during the course of treatment, thereby helping to avoid surrounding healthy tissue.

IGRT is most commonly used in conjunction with IMRT to treat tumors in areas of the body that move regularly. For instance, tumors in the lungs, which move to the act of breathing, are likely to receive IGRT treatment. Similar to lung cancers, tumors located in critical organs or near delicate tissue can also receive this precise type of treatment.
