What is intensity-modulated radiation therapy (IMRT)?
Intensity-modulated radiation therapy (IMRT) uses a powerful machine called a linear accelerator to break a radiation beam into many smaller beams.
With IMRT, doctors can direct high doses of radiation right at a tumor, sparing nearby healthy tissue.
IMRT: What to expect
The more precisely we hit a tumor with focused radiation, the more effectively we destroy cancer cells. Many patients experience fewer side effects from IMRT than from other radiation therapy.
Our experts use a specialized technique called volumetric modulated arc therapy (VMAT) to shape the radiation dose to the tumor with incredible precision.
VMAT reduces your treatment time per session. IMRT sessions with VMAT can take as little as one minute per treatment. Less time in treatment means more time to focus on things that matter to you.
We use a special surface imaging system to track your breathing while you receive IMRT. Our technology ensures you lie in the exact same position for every treatment. This level of detail leads to highly effective cancer-destroying effects while protecting healthy tissues.
How to talk to your doctor about IMRT
The technical aspects of radiation therapy can be intimidating. Understanding the process can relieve your discomfort.
Your doctor will sit down with you before treatment begins to explain what you can expect. Our nurses and support professionals make themselves available to provide answers and encouragement when you need either.
Our radiation oncologists meet regularly with each other and other cancer doctors to personalize your care. This level of collaboration ensures your treatment plan fits your needs.
