Abstract

Improvements in computed tomography (CT) technology such as the introduction of spiral CT, subsecond rotation times, and multislice data acquisition have stimulated cardiac CT imaging within the last decade (Fig. 1). Cardiac spiral CT started with the introduction of dedicated phase-correlated reconstruction algorithms for single-slice spiral CT in 1997 (13). These approaches have been generalized to the case of multislice spiral CT (MSCT) acquisition (2,46) to process data of 4-slice scanners. Since then, the algorithms have been extended to the case of cone-beam scanning with 16 slices (710) and to scanners with far more than 16 slices (11). Vendor-specific implementations that take into account the cone angle have not been announced yet.
