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

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).

High
