Radiation Therapy

General Information


What is Radiation Therapy?

Radiation therapy uses focused beams of intense energy to destroy cancer cells and shrink or control the growth of tumors. Radiation therapy works by preventing targeted cells from multiplying. The objective of radiation therapy is to destroy the harmful cells while minimizing damage to healthy cells.

What is IMRT?

Intensity-modulated radiation therapy (IMRT) is a specialized form of external beam therapy that can help improve how the radiation is shaped to accurately target a tumor.

What is IG-IMRT?

Image-guided, intensity-modulated radiation therapy (IG-IMRT) is a radiation treatment guided by imaging equipment – such as CT, ultrasound or X-rays – taken in the treatment room just before radiation is given. During IG-IMRT, the images are used as a final check to ensure accurate delivery of the radiation treatment.
