3-D Conformal

3-D Conformal Radiation Therapy Overview

3-D conformal radiation therapy is a three-dimensional technique where beams of radiation used in treatment are shaped to match the shape of the tumor.

Are there Different Types of 3-D Conformal Radiation Therapy?
Previously, radiation treatments were 2-D which matched the height and width of the tumor, meaning that healthy tissue was exposed to the beams. Using technology such as CT scanners, it is possible to locate and treat the tumor more precisely.

How 3-D Conformal Radiation Therapy Is Delivered

3-D conformal radiation therapy is able to focus precisely on the tumor, while avoiding the healthy surrounding tissue. More exact targeting makes it possible to use higher levels of radiation in treatment. A higher level of radiation in treatment means that it is more effective in shrinking and killing tumors.
