Intensity-Modulated Radiation Therapy (IMRT) uses sophisticated dose calculations to design and deliver precisely targeted conformal radiation. This process involves many uniquely shaped radiation fields that are delivered to the patient using various angles and approaches.
The collimator is a motorized device in the head of the linear accelerator that consists of a number of moving leaves that position themselves dynamically. The collimator adjusts to block portions of the primary beam and creates the desired shape that mirrors the profile of the tumor. During each field of treatment, the dose delivered is contoured by the multi-leaf collimator (MLC).
Our Radiation Oncologists and on-site Physicists critically evaluate how best to avoid the healthy normal tissues and adjust radiation doses to target the tumor. IMRT is useful when treating tumors that are surrounded by critical organs or normal tissue.
