Noise
Reduction
Suppresses the mottle noise in denser areas of the anatomy while preserving detail
in the rest of the image.
Available options are:
• None – no noise reduction
•Low
•Medium
• High – maximum noise reduction
NOTE: The noise reduction feature suppresses the mottle noise in denser areas of
the anatomy while preserving detail in the rest of the image. The algorithm
takes into account tissue penetration and dose reaching the detector. For
example, if two Chest PA images were acquired on the same patient, one with
much higher dose than the other, noise reduction may only affect the lower
dose (higher noise) image. In general, the lowest Noise Reduction setting that
produces the desired image quality should be selected.
TE Settings See Tissue Equalization section for range and effect of TE sliders.
NOTE: The combined total of the TE Under-penetrated and TE Over-penetrated
areas cannot exceed 100%. The slider will automatically stop and a message
appears: “The Total Area cannot exceed 100%. Reduce the (Under- or Over-)
Penetrated area to proceed.”
