Welcome to the California HeartScan, the first and only Sacramento area provider of the revolutionary Imatron EBT HeartScan. When diagnosing early heart disease, scanning speed equals accuracy. EBT is the only scanner in the world fast enough to capture your heart's image as it beats and provide an accurate diagnostic reading. Unlike mechanical X-ray tube scanners, which produce false negatives 30 percent of the time, EBT uses a high-speed, focused electron beam to detect even minute calcium deposits that indicate heart disease. Only an EBT HeartScan can tell you that you don't have heart disease with 100 percent certainty.
