Image Guided Radiation Therapy (IGRT)
As leaders in radiation therapy, radiation oncologists at Minnesota Oncology are experts in the use of the latest therapies, including image-guided radiation therapy (IGRT) to treat cancer. IGRT uses frequent imaging during a course of radiation therapy to improve the precision and accuracy of the delivery the radiation treatment.
In IGRT, the linear accelerators (machines that delivers radiation) are equipped with imaging technology that take pictures of the tumor immediately before or even during the time radiation is delivered.
Specialized computer software compares these images of the tumor to the images taken during the simulation to establish the treatment plan. Necessary adjustments can then be made to the patient's position and/or the radiation beams to more precisely target radiation at the cancer and avoid the healthy surrounding tissue.
Respiratory Gating Movement (RPM)
RPM uses advanced technology to track the patient’s breathing motion in reference to the location of the tumor to allow accurate and precise delivery of the radiation dose to the tumor value.
