Image-guided radiation therapy, uses high-resolution x-ray imaging to effectively target, track and treat tumor sites with minimal exposure of healthy tissue. With the use of an image detector, radiologists are able to compensate for internal organ movements while the patient is in treatment position. If these internal organ movements move the tumor out of the planned treatment range, the tumor may not receive the full amount of radiation that it should or normal tissues may receive more radiation than they can tolerate.
