Radiation Oncology Technologies at ARC


At Advanced Radiation Centers (ARC), we are dedicated to offering the most sophisticated radiation therapy technologies, tailored specifically to each type of cancer. Our commitment is to combine the experience and expertise of our physicians, physicists, dosimetrists, and nursing staff with the latest advancements in radiation technology. This optimization of world-class expertise and cutting-edge technologies achieves the best possible outcomes for our patients, with minimized side effects.

Radiation comes in many forms but can primarily be broken down into two general categories: External Beam Technologies and Brachytherapy Technologies. Within each of these general categories are various technologies – each of them having certain clinical and technologic advantages and capabilities. At ARC, we are unique in having multiple technologies that can be appropriately considered and selected by your radiation oncologist, and used to tailor treatments to specific forms, stages, and individual presentations of cancers.

The two general types of radiation are:

External Beam Radiation Therapy (EBRT): EBRT is the general or generic term used to describe radiation treatment that is produced outside the body from a machine and is aimed and delivered to a target within body. EBRT compasses a broad spectrum of advanced technologies designed to deliver targeted radiation treatment to cancer cells with unparalleled precision. This method leverages high-energy beams, such as photons (X-rays), electrons or protons, directed at the tumor from outside the body, minimizing damage to surrounding healthy tissues. At the core of EBRT’s effectiveness are its capabilities in accuracy, advanced imaging integration, and versatile dose delivery mechanisms, catering to a wide array of cancer types and individual patient needs.

Various types of machines (linear accelerators) are made for delivering radiation for EBRT including technologies such as Stereotactic Radiosurgery (SRS), Stereotactic Body Radiotherapy (SBRT), Volumetric Modulated Arc Therapy (VMAT) and Intensity Modulated Radiation Therapy (IMRT), Image Guided Radiation Therapy (IGRT) and Respiratory Gating.

Brachytherapy: Brachytherapy comes from the word “brachy” or “close” – and it is a close therapy as the radiation itself, usually from a radioactive source or isotope, is placed directly into the body, either in the form of radioactive seeds, injectable radiations, or even those that can be swallowed. The most common forms of brachytherapy today are prostate seed implants, or intravenous radiation for cancers such as Xofigo (Radium-223) or Pluvicto (Lutetium-177 based).
