GE Healthcare Discovery CT750 HD - Manual (Page 37)

The Data Acquisition System (DAS)
Volara* DAS technology delivers improved signal
performance and image quality.
A dramatic reduction in
electronic noise
– Low noise, for outstand-
ing image quality in high
and low signal areas of
the anatomy
Improved spatial
resolution across entire fi eld
of view
– 2.5X more views per
rotation to improve x & y
resolution, and reduce
artifacts
– 7.1 kHz sampling rate
The Tube
The Performix* HD Tube enables the visualization of
more detail with dynamic focal spot control.
Power at your fi ngertips
– Increased data sampling
– Ultra-fast kVp switching
– Up to 570mA on the small focal spot
The reconstruction
Critical to limiting dose, ASiR 1 on the Discovery CT750 HD,
may also aid in delivering clarity via an increase in low
contrast detectability of up to 40% and further artifact
suppression. And with Veo, clinicians can achieve
previously unheard of image quality at doses lower
than ever before — a bold step into the future of high-
defi nition CT imaging.

1. In clinical practice, the use of ASiR and Veo 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.
LCD was measured using the Statistical LCD technique, which is
based on an analysis of the pixel standard deviation on the
uniform section of the CatPhan (R) 600 phantom. The
improvement is demonstrated at 120kVp, when comparing ASiR
images acquired with 40% lower mAs to full dose FBP images.
