Image Guided Radiation Therapy (IGRT)
IGRT is an advanced cancer treatment endorsed by the American College of Radiology. It utilizes two and three-dimensional imaging to ensure correct patient (and consequently tumor) positioning prior to the delivery of the radiation treatment. This helps ensure delivery of the radiation energy to the specific target location for more effective treatment and a minimized risk of damage to surrounding tissue. The imaging procedures are performed simultaneously to provide real time data to the doctor.
There are several different types of imaging technologies that may be used during radiation therapy, including computed tomography, fluoroscopy, optical tracking, MVCT and others. Your doctor will decide which type is best to help visualize your treatment area.
