External beam radiation therapy
|
The McGivney Center was the first in Connecticut to
offer a technology called three-dimensional conformal
radiation therapy.
In traditional radiation therapy, a machine called a linear accelerator is used to aim high-energy particles or waves at a tumor, destroying or damaging its cancer cells. But by using a sophisticated computer system, radiation oncologists can now construct a three-dimensional model of the patient’s tumor, accurately depicting its shape, size and location. This information is then used to create a customized pattern of radiation in which multiple beams are precisely positioned to conform to the shape and size of the tumor. It is much more accurate, allowing radiation beams to precisely target only the tumor, leaving the surrounding healthy tissues untouched. This technology has resulted in fewer side effects and complications as well as improved tumor control. To prepare for three-dimensional conformal radiation therapy, you will undergo two simulation procedures, and your treatment team will make extensive plans.
