GE Healthcare Discovery CT750 HD - Manual (Page 4)

Filtered Back Projection (FBP)
The Discovery * CT750 HD is designed
to deliver up to 50% 1 lower dose,
helping assure patients with faster,
more confident diagnoses.
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.
