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.

Routinely image with up to 82% less dose^1,2. Combining the speed of ASiR* with added capabilities from Veo* full model-based iterative reconstruction, the novel ASiR-V* iterative reconstruction algorithm brings low dose and improved quality to routine imaging.
Up to 100% better spatial resolution. 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.
Up to 135% improved low-contrast detectability. ASiR-V improves the detectability of low-contrast objects by up to 135% when compared to corresponding FBP reconstructions at the same dose.
Up to 91% less 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.

Confident diagnosis with lower dose with ASiR*

Adaptive Statistical Iterative Reconstruction (ASiR)
May enable reduction in pixel noise standard deviation
May allow for reduced mA in the acquisition of diagnostic images, thereby reducing the dose required¹
May enable an improvement in Low Contrast Detectability²
Further dose reduction in cardiac exams combining ASiR with SnapShot Pulse*

Imaging under 1mSv with profound clarity with Veo*

Model-based, iterative reconstruction product
Allows reduced mA or kVp in the acquisition of diagnostic images, thereby reducing the dose required¹
May enable improvement in low contrast detectability and spatial resolution
Reduces low signal artifacts generated by dense anatomy or metal implants compared to FBP²
Veo is only available on Revolution HD

Dose reduction capabilities along the imaging chain with Optidose

Limit penumbra and helical over-scanning with Dynamic collimation (SmartTrack*)
3D automatic dose modulation

Alerts when a pre-determined dose level will be exceeded with Dose Check

A prompt alerts your operator to the situation
The operator can then either change the scan or override the notification
All overrides are documented, providing an audit trail for future analysis

Dose management with Dose Watch

Uses data acquired from imaging systems
Retrieves, tracks, reports, and monitors the radiation dose delivered to patients during an examination
Presents data in an organized manner
Multi-modality and multi-manufacturer
It can be adopted in any imaging program
