Dose Information
Principle of automatic tube current adaptation by
CARE Dose 4D for a spiral scan from shoulder to pelvis
(very high table feed for demonstration): High tube
current and strong modulation in shoulder and pelvis,
lower tube current and low modulation in abdomen
and thorax. The dotted lines represent the min. and
max. tube current at the corresponding table position
and result from the attenuation profile of the Topo-
gram.
The mAs value displayed in the user interface and in
the patient protocol is the mean (eff.) mAs value for
the scan range.
The mAs value recorded in the images is the local (eff.)
mAs value.
