3D Conformal Radiation Therapy

What is 3D Conformal Radiation Therapy?

3D Conformal Radiation Therapy is an advanced cancer treatment technique designed to improve local tumor control by precisely targeting tumors while protecting healthy tissue. Using three-dimensional imaging, this method delivers radiation doses that conform closely to the tumor’s exact shape, reducing damage to surrounding tissues.

Local Tumor Control

Effective local tumor control is critical in cancer treatment. Without it, tumors can spread, leading to distant metastases and decreased survival rates. However, because tumors are often irregular in shape and surrounded by sensitive normal tissue, traditional radiation approaches can struggle to deliver effective doses without affecting healthy areas.

How 3D Conformal Radiation Therapy Works

This technique uses “Beam’s eye-view” imaging powered by advanced computer technology to map tumors in three dimensions (width, height and depth). The improved imaging creates highly precise treatment plans tailored to the tumor’s unique shape.

At Stony Brook's Department of Radiation Oncology, the Eclipse treatment planning system enables our team to provide state-of-the-art 3D conformal radiotherapy. Radiation oncologists, dosimetrists and physicists collaborate to design radiation beams that fit the contours of each patient’s tumor. This reduces exposure to healthy tissues, minimizes side effects and increases the likelihood of successful tumor control.
