Intensity modulated radiation therapy (IMRT)

Intensity modulated radiation therapy (IMRT) is specialized  3D-CRT that precisely shapes radiation to fit a tumor.  Radiation beams are broken into many smaller “beamlets,” and the intensity of each is adjusted individually.  IMRT further reduces   the amount of radiation to normal tissues near the tumor. IMRT also may allow a higher dose of radiation to the tumor, increasing the chance of a cure. 

Saint Joseph’s uses Varian’s SmartBeam® IMRT for a number of tumor types including brain, head and neck tumors, prostate cancer and other areas that require focal high doses of radiation.
