Radiation therapy is the use of high-energy X-rays or particles to treat cancer. It is a localized type of treatment, meaning it is highly concentrated and focused only on the treatment area.
Sophisticated computer equipment and precise calculations are used to map tumors before treatment. This ensures that the radiation targets the tumor without harming healthy surrounding tissue.
The Hospital of Central Connecticut offers the most advanced external radiation therapy techniques and technology, including:
Novalis® radiosurgery system
Conducts non-invasive stereotactic radiosurgery, a form of treatment that uses highly focused radiation to precisely target tumors and lesions in the brain, near the spinal cord and in other areas of the body. Learn more about Novalis
3-D Conformal Radiation Therapy (3DCRT)
A computer constructs a three-dimensional view of tumors to pinpoint their shape, size and location. Multiple radiation beams are positioned to conform to the tumor shape, improving accuracy and sparing surrounding tissue.
Intensity Modulated Radiation Therapy (IMRT)
Delivers precise radiation doses to a cancerous tumor or specific areas within the tumor. The radiation dose is designed to conform to the shape of the tumor by modulating - or controlling - the intensity of the radiation beam to focus a higher radiation dose to the tumor while minimizing radiation exposure to surrounding normal tissues. Two types of IMRT include:
- Image-Guided Radiation Therapy (IGRT) - Images of the treatment area are taken from two directions before daily treatment, allowing technologists to compensate for any movement or variations of the tumor area and further increasing the accuracy of IMRT treatments.
- Acculoc™ markers - The prostate gland is particularly prone to movement. Acculoc markers - small seeds - are implanted around the affected area of the prostate to mark the site internally. CT scans are taken before treatment to locate the seeds and coordinates are entered into the computer so that radiation can be precisely targeted.
