GE Healthcare Discovery NM_CT 670 - Manual (Page 8)

ASiR
GE Healthcare offers an industry-proven adaptive statistical iterative
reconstruction that may deliver noise performance (pixel standard
deviation) equivalent to an acquisition with higher generator power
and may allow for scanning at lower mA and less anode heat,
thereby reducing tube cooling limitations.
†
With our exclusive ASiR technology, Discovery NM/CT 670 may enable
reduction in pixel noise standard deviation and may allow for reduced
mA in the acquisition of images, thereby reducing the dose required.
†
ASiR technology may enable improvement in low contrast
detectability.
†
† 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.

Neurology
Innovative high-resolution Elite NXT detectors with 9.5% energy
resolution and outstanding 9.9 mm SPECT resolution enhanced by
brain SPECT-optimized ultra-flared fan-beam collimators deliver
high-quality Neuro-scintigraphy.
With BrightSpeed Elite’s 0.625 mm slicing and the Neuro 3D Filter,
which delivers image-quality improvement in noise reduction
(measured by pixel standard deviation) at the same dose level, the
Discovery NM/CT 670 is an excellent tool for neurology studies.
ASiR
Less noise. Better contrast. Easier to trace borders
between gray and white matter.
