Contrast Medium
Bolus Tracking
An automatic Bolus Tracking program is available
which enables triggering of the spiral scanning at the
optimal phase of the contrast enhancement.
Additional Important Information
1.This mode can be used in combination with any spi-
ral scanning protocol. Simply insert Bolus Tracking
by clicking the right mouse button in the chronicle.
This inserts the entire set-up including pre-monitor-
ing, i.v. bolus, and the monitoring scan protocol. You
can also save the entire set-up in your own scan pro-
tocols.
2.The pre-monitoring scan is used to determine the
position of the monitoring scans. It can be per-
formed at any position of interest. You can also
increase the mAs setting to reduce the image noise
when necessary.
3.To achieve the shortest possible spiral start delay
(2 s), the position of the monitoring scans relative to
the beginning of spiral scan must be optimized.
A snapping function is provided:
– After the topogram is performed, the predefined spi-
ral scanning range and the optimal monitoring posi-
tion will be shown.
– If you need to redefine the spiral scanning range,
you should also reposition the monitoring scan in
order to keep the shortest start delay time (2 s). (The
distance between the beginning of the spiral scan-
ning range and the monitoring scan will be the
same).
