This is an automatic Bolus Tracking program, which 
enables triggering of the spiral scanning at the optimal 
phase of the contrast enhancement.

• This mode can be applied in combination with any 

spiral scanning protocol. Simply insert “Bolus Track-
ing” by clicking the right mouse button in the chron-
icle. This inserts the entire set up including pre-mon-
itoring, i.v. bolus and monitoring scan protocol. You 
can also save the entire set up as your own scan pro-
tocol.

• 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.

• 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).
