Radiation therapy is offered at the Requard Radiation Oncology Center, located at the Cancer Center, which is accredited by the American College of Radiology/American Society for Radiation Oncology.
The Requard Radiation Oncology Center provides patients with a full spectrum of radiation therapy services that use advanced equipment and techniques to provide precise treatments for tumor types and locations – often with the benefit of sparing healthy tissue and reducing side effects.
Equipment and techniques include:
- External beam radiation therapy is the most common type of radiation therapy used for cancer treatment. A machine is used to aim radiation beams from outside the body into the tumor. The machine we use is a Varian linear accelerator.
- Three dimensional treatment planning (3D-CRT) delivers radiation beams from different directions designed to match the shape of the tumor. This helps to reduce radiation damage to normal tissues and better kill the cancer by focusing the radiation dose on the tumor.
- Intensity modulated radiation therapy (IMRT) is like 3D-CRT, but It also changes the intensity of the beams to deliver a more precise dose of radiation to the tumor while further reducing the amount of radiation to healthy surrounding tissue.
- High-dose-rate (HDR) brachytherapy (sometimes referred to as internal or intracavitary radiotherapy) involves placing radioactive sources in or next to the cancer.
- Stereotactic radiosurgery (SRS) isn’t really surgery, but a type of radiation treatment that treats inoperable cranial and spinal tumors with very fine and ultra-precise radiation beam. These treatments usually are delivered in 1 to 5 sessions versus over the course of several weeks when compared to normal external beam radiation therapy.
- Stereotactic body radiotherapy (SBRT) is the same as SRS except it is used to treat sites outside of the cranium and spine.
- Image-guided radiation therapy (IGRT) x-rays are used to accurately align the patient prior to treatment based on each individual patient’s internal anatomy.
- On-site big bore CT scanner is used to determine the exact size, shape, and location of the tumor and this information is used to create an individualized treatment plan.
