GE Healthcare Discovery CT750 HD - Manual (Page 17)

ASiR may reduce dose by
up to 50%
1 by allowing the
use of lower mA protocols —
and with high definition
image quality across all
anatomies — the Discovery
CT750 HD can reach any
part of the body, any age
patient, and any application
that demands the leading
edge of CT clarity.
1. In clinical practice, the use of ASiR may reduce CT patient dose
depending on the clinical task, patient size, anatomical location
and clinical practice. A consultation with a radiologist and a
physicist should be made to determine the appropriate dose to
obtain diagnostic image quality for the particular clinical task.
ASiR dose reduction was measured on a standard 20cm water
phantom. The test involved maintaining constant pixel standard
deviation as the mA was reduced at 120 kVp.
