Abstract
Electron beam computed tomography (EBCT) employs well-known computed tomography technology. However, in distinction to other CT machines, no mechanical parts are moved. Whereas in usual CT machines, the distance between cathode and anode is very short, it measures approx 9 ft in EBCT. The electron beam, which produces the X-rays by striking the anode, is steered over this distance by an electromagnetic deflection system. The latest generation of EBCT machines (e−Speed™, GE Imatron) achieves an image acquisition time of only 30 ms, which is sufficient to freeze the motion of the heart.
