ATLANTA, Sept. 15 /PRNewswire/ -- Presbyterian Cancer Center - Dallas, a joint venture between Presbyterian Hospital of Dallas and Texas Oncology, PA, recently installed an Elekta Infinity system, enabling the facility to begin treating patients with Volumetric Modulated Arc Therapy (VMAT). Elekta Infinity is the facility's first image guided linear accelerator, and will allow the Center to offer patients shortened treatment times with the highest degree of precision.
"We are excited to be able to provide patients with the benefits afforded by the image guidance and VMAT technology of Elekta Infinity," says Kyle Antes, M.S., Director and Chief Physicist for Presbyterian Cancer Center. "On average, we treat about 65 patients a day, and we anticipate this system will result in increased time savings, highly conformal treatment and a better overall experience for our patients."
VMAT with Elekta Infinity varies the radiation beam during treatment by simultaneously manipulating the gantry position and speed, MLC leaves, dose rate and collimator angle for precise beam shaping without interrupting treatment delivery. As a result, Elekta VMAT delivers more radiation to the target while sparing healthy tissue, in significantly less time. Faster treatment times improve patient comfort, which makes it easier for the patient to remain still during treatment and increases the likelihood of delivering radiation more accurately and safely.
By implementing Elekta VMAT, Antes also anticipates reducing treatment times by half for head and neck patients. What were formerly 30-minute time slots are now only 15 minutes, making it easier for the Center to schedule patients. Patients also experience the benefits of no longer having to lie still, while wearing a tight mask for 30 minutes.
To visualize the prostate, the Presbyterian Cancer Center had
previously used gold seeds with MV portal imaging, explains Antes. "Not
only did this take longer, we were
