Design, Technique, and Future Perspective of Multislice CT Scanners

The introduction of spiral CT in the early 1990s laid the foundation for a fundamental improvement in CT imaging (Kalender et al. 1990; Crawford and King 1990). For the first time volume data could be acquired without misregistration of anatomical details, which initiated the development of three-dimensional image processing techniques such as multi-planar reformations (MPRs), maximum intensity projections (MIPs), surface-shaded displays (SSPs) or volume-rendering techniques (VRTs). However, as a consequence of increasing clinical demands single-slice spiral CT with 1 s gantry rotation time soon encountered its limitations. The ideal of isotropic resolution, of acquiring image voxels with comparable sizes in all three dimensions, could only be met by a substantial reduction of the scan range (Kalender 1995). The first step towards larger volume coverage and improved transverse resolution was a two-slice CT scanner introduced in 1993 (Elscint TWIN).
