Optics provides significantly improved imaging efficiency from photon generation to detection. An optimized beam spectrum combined with a more efficient detector result in a better balance between image quality and dose.
Patient specific beam shaping filters provide an optimized X-ray spectrum and more homogenous distribution, improving low contrast detectability by up to:
*A non-prewhitening model observer study was conducted comparing Aquilion Prime SP to the Aquilion PRIME. Dose reduction values were established by comparing low contrast detectability under baseline conditions for abdominal and brain examination.Based on the detectability index performance metric, a measure of signal to noise that takes into account the magnitude and texture of both the signal and the noise for a given LCD task.
- 19% improved LCD at equivalent dose—brain*
- 22% improved LCD at equivalent dose—body*
- 31% dose reduction at equivalent low contrast detectability*
