Cancer Treatment Using Intensity-Modulated Radiation Therapy (IMRT):
Intensity-Modulated Radiation Therapy (IMRT) is an advanced method of delivering a high-precision dose of radiotherapy from a linear accelerator in cancer treatment. With the use of our computer-controlled linear accelerators, IMRT is precisely delivered to a malignant tumor or specific areas within the tumor.
IMRT allows for the radiation dose to conform more precisely to the three-dimensional (3-D) shape of the tumor by modulating—or controlling—the intensity of the radiation beam in multiple small volumes. IMRT also allows higher radiation doses to be focused to regions within the tumor while minimizing the dose to surrounding normal organs and critical structures.
Treatment is carefully planned by using 3-D computed tomography (CT) or magnetic resonance (MRI) images of the patient in conjunction with computerized dose planning systems to determine the radiation dose pattern that will best conform to the tumor shape. Typically, combinations of multiple intensity-modulated fields coming from different beam directions produce a custom tailored radiation dose that maximizes tumor dose while also minimizing the dose to adjacent normal tissues. Standard daily treatment times are about 10-15 minutes each day.
