An advanced version of 3D conformal radiation therapy is called intensity modulated radiation therapy, or IMRT.
IMRT is a highly accurate technique for the delivery of radiation treatments. IMRT uses either multiple “static” beams or “arc” therapy to optimize radiation dose to the target structure while minimizing radiation dose to the non-target normal structures. In doing so, IMRT can be used to treat tumors adjacent to, or within, critical organs.
In some diseases, such as prostate cancer, higher radiation doses with IMRT now allow better tumor control than was previously possible. In carefully selected cases, this technology has allowed radiation oncologists to make a meaningful difference to improve the outcomes for patients.
Currently, Radiation Oncology Associates provides IMRT at all of our locations in New Hampshire and Massachusetts:
