Radiation Therapy

State-of-the art radiation therapy delivered by leaders in the field of veterinary radiation oncology.

The Region's Most Qualified Radiation Oncology Team

TOS is proud to offer consultation and radiation care from residency-trained and board-certified radiation oncologists at our Leesburg and Springfield practices. View Dr. Gordon and Dr. White's biographies for more information about their training and qualifications and see why TOS is proud to have the most qualified radiation oncology team in the region.

The practice of veterinary radiation oncology depends on advanced technology. Both of our radiation centers utilize isocentric linear accelerators capable of targeting tumors with a high-energy radiation beam.

Wide Applications

In veterinary medicine, radiation is used for both curative-intent and palliative-intent treatments for a wide variety of tumor types including:

  • Soft tissue sarcomas
  • Mast cell tumors
  • Osteosarcoma and other bone tumors
  • Nasal tumors
  • Brain and pituitary tumors
  • Oral tumors including melanoma, squamous cell carcinoma, and fibrosarcoma
  • Thyroid tumors
  • Anal sac tumors
  • Genitourinary tumors including prostatic and bladder tumors
  • Spinal tumors
  • Localized lymphoma, plasma cell tumors, and histiocytic sarcoma
  • Heart-base tumors

State-of-the-Art Technology & Resources

Our new radiation center in Leesburg is also fully equipped to deliver the most advanced forms of radiation therapy including electron therapy, intensity modulated radiation therapy (IMRT), and stereotactic radiation therapy. "Albert", our linear accelerator is equipped with the following highly-advanced features.

Stereotactic Radiation Therapy

We are excited to provide Stereotactic Radiation Therapy (SRT) at our new Comprehensive Veterinary Cancer Center in Leesburg, VA. SRT is typically completed in 1-4 treatments within a single week, instead of the standard 15-18 treatments given over 3 weeks needed with conventional radiation therapy.

SRT is most effective for the treatment of tumors that are difficult to reach with surgery alone. This level of precision requires specialized equipment for treatment and image guidance as well as highly accurate patient positioning and immobilization devices available.

Radiation Therapy

Benefits of Stereotactic Radiation

  • Non-invasive painless procedure
  • Fewer treatments, shorter treatment time
  • Greater treatment accuracy
  • Improved sparing of normal tissues (fewer side effects)
  • Improved outcomes for certain tumor types

Board-certified in Veterinary Radiation Oncology, Dr. Ira Gordon looks forward to working with you and providing you the best in veterinary radiation therapy.

Intensity Modulated Radiation Therapy (IMRT)

IMRT is a sophisticated treatment planning technique that requires advanced imaging and 3-dimensional treatment planning software to dynamically shape a radiation dose to conform to almost any target with a complex shape. This can allow for increased sparing of critical structures that are close to the tumor target. A common example is the use of IMRT to spare the dose to the eyes when treating a nasal tumor or a tumor around the orbit of the eye. This can decrease normal tissue side effects and/or allow for escalation of radiation dose to the tumor.

Electron Therapy

Most radiation treatments utilize a type of radiation known as photons which are most effective for targeting deep-seated or complex shaped lesions. For superficial tumors though, electron therapy is a alternative that allows greater sparing of structures located deep to the tumor. A radiation oncologist can select a particular electron energy that will penetrate to the appropriate depth of tissue and spare tissues that are beyond the target. Electron shielding blocks can be custom cut with our block cutting equipment and cerrobend alloy to match the shape of almost any target. Electron treatments are most useful for superficial tumors located over critical tissues such as the chest or abdominal wall.
