Scan at 50-Slice equivalent CT Speed
IQ Enhance allows you to:
- Reduce Helical Artifacts Index in thin-slice helical scans. This reduction in artifacts makes it possible to scan at faster helical pitches.1
- Accelerate helical pitch, up to 70% (e.g. 0.562 to 1.75, @16 slice) at the same Artifact Index level.1
1. Helical Artifact Index is defined as: ((SD value at ROI1)2 - (SD value at ROI2)^2)1/2. Two helical data sets were acquired to compute a Helical Artifact Index. Both helical acquisitions were acquired using kV:120, Gantry Rotation: 0.8S, Slice Thickness: 1.25mm, SFOV: Large, DFOV: 32cm, Start/End: S200-I370 and reconstructed using 512 matrix. One data set was acquired at 1.75:1 pitch with table speed of 37.5mm per rotation with IQ Enhance ON at 260mA and the other using 0.562:1 pitch with table speed of 11.25mm per rotation with IQ Enhance OFF at 160mA.
