Cancer center receives new technology
On Monday, August 24, the Southeast Cancer Center used its Optical Surface Monitoring System (OSMS) for the first time during a stereotactic radiosurgery procedure. OSMS is also indicated for use in stereotactic body radiotherapy and deep inspiration breath hold radiation therapy.
"As we deliver radiation to the accuracy of .1mm, we have to ensure the patient remains still to the same degree," said Scott Griffin, director, Southeast Cancer Center.
The OSMS technology monitors patient movement during treatment by comparing images from ceiling mounted sensors to existing CT imagery that was created during treatment planning. If movement is detected, beam delivery is interrupted until the patient returns to the allowable position for treatment.
"This is somewhat of a first for the nation," Griffin added. "Although OSMS technology is not new, our application is the first time it has been retrofitted to a Varian Trilogy linear accelerator. Typically OSMS is integrated with the installation of a newer accelerator."
OSMS will be included when SAMC installs its new True Beam linear accelerator later this year. This will double our capacity for these advanced procedures, which require involvement from our neurosurgeons.
Bucky Buchanan, chief nuclear physicist, Radiation Oncology, performs quality assurance tests prior to the first stereotactic radiosurgery case using OSMS on August 24.
