![]() Some typical treatment sites include the prostate, brain, and breast. IMRT is ideal for tumors situated near critical structures such as the spinal cord, heart, and eyes. ![]() Less radiation to normal tissues translates into fewer complications for patients. This treatment technique provides the means to escalate tumor doses while significantly sparing normal tissue. With sophisticated dose calculation methods, each leaf can move independently to create tiny beamlets of radiation that specifically target a tumor. The leaves conform to the shape of the tumor and block out unwanted radiation. These tiny beams are produced by using a highly sophisticated computer program that will dissect the cancer tissue from normal tissue, and assign the radiation beam intensity differently to the tiny areas, as directed by the doctors. The radiation intensity of these beams is modulated or controlled, with a system of movable leaves called a multi-leaf collimator (MLC). ![]() ![]() Intensity-modulated radiation therapy (IMRT) an utmost three-dimensional radiation treatment plan where thousands of tiny beams from several beam angles are used to target a tumor. High-Definition multi-leaf collimator (MLC) ![]()
