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 inter-scan 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.
