ASiR-V is a reconstruction technique that enables reduction in image noise (standard deviation),
streak artifact at low signal condition and improvement in LCD (Low Contrast Detectability),
while preserving the structure details in the image.
ASiR-V can be used to reduce the image noise (standard deviation) and streak artifact in
diagnostic images and thereby reduce the dose required for routine imaging.
The scanner allows you to select levels of ASiR-V.
These "levels" provide a varying degree of noise removal from the images. As shown in
Illustration 1
MTF remains constant as the ASiR-V level is increased.
