LOS ANGELES, Calif., June 8 -- GE Medical Systems has developed a new medical imaging technique that combines X-rays and radioactive tracers injected into the body to identify health problems and diseases. Called functional anatomic mapping, it could cut health care costs by providing a clearer picture of the specific surgery or therapy needed, according to a spokesperson for GE Medical, a unit of General Electric Co. Functional anatomic mapping technology utilizes standard nuclear medicine imaging techniques to form a resultant image that is a perfect combination of anatomy and physiology -- this is a significant departure from how we review images today, said Beth Klein, general manager of GE's global nuclear medicine business.
