- As demonstrated in mechanical and mathematical cardiac phantom testing
- SnapShot Freeze 2, in conjunction with 0.23 s/rotation gantry speed, provides a reduction in coronary motion artifacts that is equivalent to a 0.039 s/rotation equivalent gantry rotation speed with effective temporal resolution of 19.5 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 0.039 s/rotation images are modeled without application of SnapShot Freeze 2. Results may vary in clinical applications.
