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.
