Electron Beam Tomography is not experimental; in fact, it is considered to be the gold standard for the measurement of coronary calcium through extensive peer-reviewed research and is used in some of the most prestigious medical institutions in the United States and around the world. The measurement of coronary calcium using EBT is the best non-invasive technique for the early detection and prevention of heart disease.

The EBT scanner combines advanced science and technology to create an innovative diagnostic imaging system. Dramatically different from conventional (mechanical) CT scanners, GE Imatron's patented electron beam technology and unique design offer scan times as fast as 50 and 100 milliseconds, high quality images, repeatability of results from machine to machine and low radiation.

Utilizing proprietary EBT technology, a powerful electron beam is generated and then focused onto one of four tungsten target rings positioned beneath the patient. Each 210-degree sweep of the electron beam produces a continuous 30-degree fan beam of x-rays that pass through the patient to a stationary array of detectors, which generates cross-sectional images.

Freeze Frame
In a 5-minute test, the electron beam scanner takes forty pictures of your heart, between beats, while you remain fully clothed. This “freeze frame” of the heart-in-motion is what allows images to show the early calcified plaque build-up, which appears as white specs on the walls of your arteries. At the end of the test, you will be given a calcium score for each of your coronary arteries and a total score for your heart. This score directly correlates with your risk for heart attacks and can be used by your doctor to guide your treatment program.
