Supporting Materials

*As demonstrated in phantom testing using a commercially available motion phantom with linear motion of variable velocity. The 6x improvement is referenced against images without application of Snapshot Freeze 2. Results may vary in clinical applications.

**Snapshot Freeze 2, in conjunction with 0.28s/rotation gantry speed, provides a reduction in coronary motion artifacts that is equivalent to a 0.047s/rotation equivalent gantry rotation speed with effective temporal resolution of 24 msec. As demonstrated in phantom testing using a commercially available motion phantom and also with a mathematical cardiac phantom with linear motion of variable velocity. The 0.047 s/rotation images are modeled without application of Snapshot Freeze 2. Results may vary in clinical applications.

SnapShot Freeze 2 is available on GE AW workstation 4.7 ext.18 (or later) or via the CT Smart Subscription Cardiology package.
