Types of Radiation Therapy

Personalized Treatment Plan & Delivery with Advanced Radiation Technologies

Delivering precise radiation to the tumor while also sparing nearby healthy tissue and organs requires the development of a detailed, personalized treatment plan. While the treatment plan helps determine the exact area where the radiation needs to be focused (the "treatment field"), it also considers the patient's quality of life during and after treatment.

The latest technologies used at the SCI to develop a treatment plan and then ultimately treat cancer with radiation therapy include:


Active Breathing Coordinator for Breast Cancer

Provides patients with left-sided breast cancer maximum protection from radiation to their hearts.

Calypso® 4D Localization System for Prostate Cancer

GPS for the body to assist with precision-guided prostate cancer treatments.

Learn More


Partial-Breast Irradiation

Maximizes the dose delivered to the area most at risk of breast-cancer recurrence while minimizing radiation exposure to surrounding healthy tissue.

Learn More


High Dose Rate Brachytherapy

The temporary placement of an intense radiation source directly in or around a cancerous tumor.

Learn More


Lung-Saving Brachytherapy

Saving the lungs of high-risk patients who can’t afford or don't want to lose an entire lung during surgery.

Cyberknife Radiosurgery

A computerized, robotic radiosurgery system delivering beams of high-dose radiation from multiple angles to precisely target and destroy tumors.

Learn More


Gamma Knife Radiosurgery

Delivers mutiple beams of radiation from multiple angles to a specific target with pinpoint accuracy while avoiding damage to the surrounding tissue.

Learn More


Intensity-Modulated Radiation Therapy (IMRT)

3-D conformal radiation therapy that allows customization of the radiation dose.

Learn more


Image-Guided Radiation Therapy (IGRT)

All-digital device allows physicians to see a tumor at the exact time of treatment, even if a tumor has moved due to a patient's breathing, heartbeat, gastrointestinal changes or other activities.

Learn More



Combines 3D-imaging technology with rotational delivery of intensity-modulated radiation, which results in highly focused radiation therapy and unprecedented accuracy.

Learn More


Volumetric Modulated Arc Therapy (VMAT)

VMAT allows the delivery of high radiation doses with exceptional precision, resulting in fewer side effects and faster treatment times.
