CARE Dose
CARE Dose is a clinical application package that pro-
vides real-time tube current modulation for Spiral and
Sequential Scanning.
CARE Dose reduces patient dose significantly, espe-
cially in the regions of shoulder and pelvis. It decreases
tube load, which extends the capacity for volume
scanning with thinner slices, larger volumes or Multi-
phase studies.
It can also improve image quality by increasing mA
and thus reducing image noise on the lateral views.
How does it work
It reduces the mA for low attenuation views up to 90%
and keeps the nominal higher mA for high attenuation
views, e. g. in the lateral projection (Fig. 1). This is done
“on-the-fly”, i. e. the scanner adapts the mA in real-time,
according to the patient’s attenuation profile (Fig. 2).
