Modulated tube current

• CARE Dose is pre-selected by default for most standard

protocols, except head and cardiac protocols. It can

be switched on/off in the scan card.

• The application of CARE Dose does not require any

changes in the scan parameters. The mAs, however,

should be adapted to patient size manually for obese

and pediatric patients.

• The mean value of the mAs applied will be lower than

what you have selected. Although the average mA

for the entire scan will be lower than selected, we

allow the scanner to apply increased mA levels for the

high attenuation views. This may cause different

results of the tube load controller when switching on

and off CARE Dose.

• The mean value of the effective mAs applied is shown

in the image text.
