For Revolution EVO, we redesigned the entire imaging chain using the new Clarity detector inherited from the breakthrough technology introduced on Revolution CT.
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 dose1,2. 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.
The significant dose reduction using the new generation of iterative reconstruction ASiR-V, allowed the customer to manage a better follow-up of this young patient, with high image quality and less than half dose.
1 Low contrast detectability (LCD), image noise, spatial resolution and artifacts 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 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 consultationwith a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task.
