VolumeShuttle—twice the coverage with less doseVolumeShuttle helps make the most challenging neuro CT perfusion and angiographic studies routine, doubling the acquisition coverage to 80mm, while reducing dose up to 24%. Because of ASiR reconstruction technology, dose can be reduced by up to 40%.
This capability allows practitioners to perform studies such as 4D-CTA and CTP in a single scan and with a single contrast injection. For neuro imaging it ensures ample coverage to perform “whole territory perfusion” (from the basal ganglia to the top of the lateral ventricles). |
Volume Helical Shuttle — covers up to 500 slices for 4D CTA
First introduced on the Discovery CT750 HD, Volume Helical Shuttle helps extend anatomical assessment even further. The technique allows you to cover the range you need while avoiding the cone-beam artifact of today’s widest detectors. Volume Helical Shuttle is a continuous bi-directional scan mode that extends z-coverage and improves temporal sampling. GE’s exceptional Dynamic Pitch reconstruction method utilizes acquired scan data during table acceleration and deceleration rather than only during constant table speed. This innovative approach can further extend coverage for expansive studies. For example, you can perform a 500 slice 4D-CTA study to characterize the inflow and outflow in the arterial and venous system, yielding highresolution volume coverage over a length of 312.5mm. In addition, Volume Helical Shuttle allows you to perform perfusion studies for the brain and body organs. |
