Scan Modes

Sequential Scanning

This is an incremental, slice-by-slice imaging mode

in which there is no table movement during data

acquisition. 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

performed simultaneously for the entire scan dura-

tion. 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

reconstructed at any arbitrary slice position. Unlike

the sequence mode, spiral scanning does not require

additional radiation to obtain overlapping slices.

Dynamic Multiscan

Multiple continuous rotations at the same table

position are performed for data acquisition. Normally,

it is applied for fast dynamic contrast studies, such as

Perfusion CT.

Dynamic Serioscan

Dynamic serial scanning mode without table feed.

Dynamic serio can still be used for dynamic evaluation

such as Test Bolus.
