Good Samaritan was the first hospital in the South Bay to offer Intensity Modulated Radiation Therapy (IMRT) coupled with Image-Guided Radiotherapy (IGRT). IMRT is an external beam radiotherapy for cancerous and non-cancerous tumors. IGRT uses computer-based imaging tools to localize and verify treatment of the target area while the patient is in position, just prior to each daily treatment. Together, these technologies offer the most advanced and precise form of radiation therapy currently available.
With our advanced IMRT technology, the radiation oncologist aims timed sequences of thin, high-dose X-ray beams with varying, or modulated intensities at a tumor from different angles. This attacks the target in a complete, three-dimensional manner, and the radiation conforms to the tumor more precisely than is possible with conventional radiotherapy. The goal is to deliver the maximum, most precise dose to the tumor while exposing surrounding tissue to the lowest dose possible to reduce the chance of radiation side effect.
When used in conjunction with IMRT, IGRT allows for unprecedented accuracy and substantially reduces treatment times. Precision is important because tumors can shift between and during treatments. We utilize dynamic targeting IGRT, which employs multiple imaging and motion management techniques for ultra-accurate tumor targeting. RapidArc® technology shortens treatment times and, with our state-of-the-art motion management techniques, patients can breathe normally during treatment sessions. Together, these approaches increase accuracy, reduce stress and improve patient comfort.
Advanced RapidArc® technology
Good Samaritan uses RapidArc technology, a major advance that improves dose conformity while significantly reducing treatment times. RapidArc delivers more precise Intensity Modulated Radiation Therapy (IMRT) with a single revolution (arc) of the machine. Treatment time is less than 2 minutes, compared to 30 minutes for the standard delivery method. Faster treatment times contribute to greater precision as there is less chance of patient or tumor movement during treatment.
Respiratory Gating for greater precision
This computerized technology enables doctors to treat tumors that may move as the patient breathes. Respiratory gating software combined with IMRT helps doctors deliver more precise doses of radiation to the tumor site. The tumor location can be mapped more precisely, and the radiation therapy can be delivered with more accuracy. For these reasons, the radiation dose can be higher, and this may make it possible for therapy to be completed in fewer visits.
