exactly what is involved in a Body Scan? It's a much larger tube than an MRI one. No noise, and only takes about 10 minutes. ELECTRON BEAM TOMOGRAPHY SCANNER All Heart Check America-affiliated centers utilize Electron Beam Tomography ("EBT") scanners manufactured by GE Imatron, Inc. of South San Francisco. The EBT scanner, developed by physicists at UC San Francisco, produces x-rays by focusing an electron beam onto tungsten target rings positioned beneath the patient. Unlike mechanical scanners, there are no moving parts in the EBT imaging chain. This results in EBT scan times as fast as 50 milliseconds (1/20th of a second), far faster than the speed attainable with the most rapid mechanical scanner. In cases where speed is essential, such as in the imaging of a moving object, e.g., the beating heart, this scan speed has brought the EBT scanner recognition within the medical community as the "gold standard". The speed of the EBT scanner provides an additional significant benefit to the patient - reduced radiation exposure. A study presented in November 2000 at the 86th Scientific Assembly and Annual Meeting of the Radiological Society of North America demonstrated that the radiation dose from a coronary artery study using a multi-slice detector CT scanner (the fastest mechanical scanner) was more than ten times the dose for the same study performed with an EBT scanner. heartcheck.com
