Scan and Reconstruction

Scan Modes

Sequential Scanning

This is an incremental, slice-by-slice imaging mode in which there is no table movement during data acquisi- tion. A minimum interscan delay in between each acquisition is required to move the table to the next slice position.

Spiral Scanning

Spiral scanning is a continuous volume imaging mode. The data acquisition and table movements are per- formed simultaneously for the entire scan duration. There is no interscan delay and a typical range can be acquired in a single breath hold.

Each acquisition provides a complete volume data set, from which images with overlapping can be recon- structed at any arbitrary slice position. Unlike the sequence mode, spiral scanning does not require addi- tional radiation to obtain overlapping slices.

Dynamic Serioscan

Dynamic serial scanning mode without table feed. Dynamic serio can still be used for dynamic evaluation, such as Test Bolus.
