The exact type of dose modulation used is preset by the selected protocol.
The user cannot change the type of modulation.
The most commonly used mode is XYZ modulation, meaning tube current is modulated
in angular as well as longitudinal directions.
If the protocol calls for two topos, the lateral should be acquired before the PA.
If 2 topos are acquired (same plane), CareDose4D will use the 2nd Topo.

The ECG shows clearly when 100% or 4% of the tube current is applied according to user
specified phase interval.

CARE kV only works in combination with CARE Dose4D.
CarekV Slider Symbols – from left to right (non-contrast, bone, soft tissue, vascular)
Please refer to the manual for detailed information on setting up CARE kV.

Siemens default protocols that use iterative reconstruction are delivered with dose
presets reduced accordingly.
Please refer to the manual for more detailed information on the settings.
