Overview

Revolution* is a family of CT scanners that helps you redefine what’s possible with CT. Each product in the Revolution family
is designed to deliver four key benefits:

  • Diagnostic confidence - innovative technologies help you acquire images that result in increased confidence

  • Patient care - ultra-low-dose from leading iterative reconstruction technologies that help you deliver great care

  • Financial performance - speed, simplicity and productivity from intelligent design help you improve your performance

  • Clinical excellence - cutting edge applications allow you to offer the fastest growing, most advanced procedures

ASiR-V

ASIR-V 


ASiR-V comes standard and focuses primarily on more advanced noise and object modeling with added physics modeling to help reduce noise, improve low-contrast detectability, and reduce artifacts.  


ASiR-V improves the detectability of low-contrast objects by up to 135% when compared to corresponding FBP reconstructions at the same dose. 




ASiR-V has the capability to improve spatial resolution compared to FBP by allowing the reconstruction of higher-resolution images with no increase in image noise. 





Depending upon the scan technique and reconstruction parameters, ASiR-V can significantly reduce electronic image noise compared to FBP at the same dose. 




Less streak artifact. ASiR-V has the capability to reduce low-signal artifact, such as streak artifact, compared to FBP.




1. Low contrast detectability (LCD), image noise, spatial resolution and artifact were assessed using reference factory protocols comparing ASiR-V and FBP. The LCD measured in 0.625-mm slices and tested for both head and body modes using the MITA CT IQ Phantom (CCT183, The Phantom Laboratory), using model observer method.  

2. Image quality as defined by low contrast detectability. In clinical practice, the use of ASiR-V 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.
