asir-v*
To make low dose routine
- Up to 135% improved low-contrast detectability.
ASiR-V improves the detectability of lowcontrast objects by up to 135% when compared to corresponding FBP reconstructions at the same dose.1 - 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.1 - 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.1 - Up to 82% less dose.
In routine imaging, ASiR-V has been shown to reduce dose by up to 82% compared to standard FBP reconstruction at the same image quality.1

1. 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. Low contrast detectability (LCD), image noise, spatial resolution and artefacts 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.
