摘要
本文介绍了Light Speed VCT的技术特性,包括硬件、软件和图像重建的技术进步,以及这些技术进步带来的图像质量上的改进和临床应用。这些先进的临床应用包括5秒心脏成像、胸痛三联诊等。探讨了降低病人剂量的重要性以及实现图像质量和X射线剂量的和谐和同一。
In this paper we introduced some of the technique advancements of GE Light Speed VCT in hardware, software and reconstruction algorithm areas,and how these advancements improved image quality and brought many advanced clinical applications into reality including 5-beat cardiac,emergency chest pain Triple Rule Out^(TM) and total stroke work-up.We also discussed the need to balance image quality and X ray dose and what GE was doing to achieve the goal of getting diagnostic CT images at the lowest possible dose.
