Intensity Modulated Radiation Therapy

IMRT is a remarkable advancement in delivery of radiation treatment. This technique allows focusing the high energy X rays to the tumor through the use of modulated beams of radiation with precision (rather than the conventional methods), so that more effective high doses of radiation are delivered to the tumor with very minima dose to healthy tissues.

Initially, special computerized tomography scan are used to precisely reconstruct the tumor (target area) and healthy tissues in three dimensions, to be visualized in dynamic fashion.

This information is utilized to construct a three-dimensional model of radiation dose distribution that determines the size and angle of each beam of radiation to avoid healthy tissues in its path to the target region. The plan thus developed, is implemented in delivering the dose of radiation utilizing an accelerator with super-specialized technology called NOVAL system. When very high doses of radiation are delivered to the tumor with minimal or no radiation to the healthy tissues, high degree of tumor control is achieved with very minimal side effects.
