拍動の影響をうけない心臓CT検査へ

Addressing the challenge of motion in Cardiac CT

複雑な動きをする心臓、あらゆる心拍数に対して1心拍撮影。
GEヘルスケア独自の動態ベクトルアルゴリズムにより、冠動脈、大動脈弁、僧帽弁、心筋など
心臓全体の、そして全心位相から拍動の影響を抑えた画像を取得、
冠動脈や心構造疾患の治療、フォローアップに貢献します。

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.
