WAUKESHA, Wisconsin—GE Medical Systems is now marketing its Millennium VG Hawkeye, an imaging system that combines CT anatomic images with PET functional images. At one clinical test site, doctors reported that Hawkeye images influenced treatment in 25% of patients, the company said in a news release.

During more than a year of intensive testing, researchers used Hawkeye to create more than 1,000 clinical images. The first test sites were at Vanderbilt University Medical Center and Rambam Medical Center, Haifa, Israel.
