Board-certified consulting radiation oncology specialist Dr. Jarred Lyons, along with our primary on-site medical oncologist Dr. Andy Novosad direct our Radiation Therapy Section. Dr. Lyons has been practicing radiation oncologist since 2007. He works collaboratively with Dr. Novosad to ensure our radiation therapy patients receive the expertise of both of doctors on our oncology team. Our Radiation Therapy Section works closely with other Sections of SLVS: Surgery, Medical Oncology, Internal Medicine and Diagnostic Imaging to provide comprehensive, multi-modal care to our patients allowing for the the best possible treatment outcomes.
With the most state-of-the art equipment available on-site at Sugar Land Veterinary Specialists, we have the capability of offering the most advanced options in radiation therapy in the region: Intensity Modulated Radiation Therapy (IMRT). This allows for more irradiation of the tumor and less effects on the normal surrounding tissues.
A linear accelerator, also called a LINAC, is a large and very heavy machine used to create a uniform, very high energy x-ray beam used to treat cancer in all parts of the body. These x-rays can destroy cancer cells while sparing the normal surrounding tissues.
The x-ray beam is projected from the LINAC Head, which is part of the gantry which rotates around the patient while delivery the tumor dose of radiation.

The x-ray beam is shaped by our integrated multi-leaf collimator to conform to the shape of the tumor. As the gantry rotates during the treatment fraction, the shape of the tumor, seen from the different gantry positions, will change. The multi-leaf collimator will simultaneously change accordingly to treat only the tumor and minimize the radiation dose to surrounding normal tissues as the gantry rotates around the patient. This advanced radiation treatment method is called Intensity Modulated Radiastion Therapy

This equipment is capable of up to 15 MEV and requires extreme shielding. The construction process is thorough and complex, requiring numerous calculations by certified and licensed radiation physicists and the State Certification. The LINAC vault is contructed of 7000 psi concrete. The floor of our vault is 36" plus 14" of sand and another 4-6" of floor concrete. The lid (ceiling) is 53", the primary walls are 53" and 45", the secondary walls are 20" and 28".
