ZeeFreeOptimal cardiac CT imaging with ZeeFree

ZeeFree, a novel reconstruction feature that enables optimal cardiac imaging independent of the detector width. It reduces misalignments usually originating from patient movement, breathing or other adjacent cardiac cycles.

Imaging the heart, a constantly moving organ, has always been a challenge. ZeeFree is a solution to tackle this issue and provide optimal cardiac image quality. ZeeFree is a flexible solution that works independently of the detector width used to acquire the data. 

It can be applied to retrospective ECG-gated spiral and prospective ECG-triggered sequence acquisitions. ZeeFree is not a post-processing feature at a workstation, instead it is a dedicated reconstruction algorithm working on the raw data. 

ZeeFree is a user-selectable option available in prospective ECG-triggered sequence and retrospective ECG-gated spiral acquisitions. It is selected from the reconstruction parameter panel Physio Recon under the label Stack Recon, which offers the choices Standard, TrueStack, and ZeeFree.
