Abstract

Cardiac imaging is a highly demanding application for any cross-sectional imaging modality. To virtually freeze cardiac motion and to avoid motion artifacts, high temporal resolution is needed. Many parts of the cardiac morphology, and especially the coronary arteries, represent small and complex three-dimensional structures that require high and at best submillimeter isotropic spatial resolution. For the last decade, CT investigation of the heart has been the exclusive domain of electron beam CT (EBCT). In these dedicated cardiac CT scanners, electrons are accelerated in a vacuum funnel and focused on four 210° tungsten target rings underneath the patient. X-ray radiation is emitted, passing through the patient, and is detected by two 240° detector rings above the patient. The design of these scanners was primarily chosen to allow for perfusion [1] and cine [2] imaging of the myocardium at eight levels, combined with a minimal exposure time of 50 ms per slice.
