Electron Beam CT of the Heart

  • David G. Hill
Part of the Contemporary Cardiology book series (CONCARD)


Electron beam tomography (EBT) was developed by Douglas Boyd, PhD, and his associates at Imatron, starting in 1977; the first clinical installation was at University of California at San Francisco in 1984. The challenge was to design a CT scanner capable of imaging the heart without motion artifacts; this required data acquisition times of 100 ms or less. In order to study perfusion, covering most of the heart without moving the patient table was also necessary. Acquisition times of 100 ms or less required a design with no moving parts except for the patient table. The result is EBT, where an electron beam generates the X-ray views needed for CT by sweeping across fixed targets.
