移动C臂X线成像系统增强脉冲模式时序分析
Control Sequence Analyses of Mobile C-arm X-ray Imaging Systems in Boost Mode
【摘要】 移动式C臂X射线成像系统在血管造影和DSA应用中为满足连续采集影像的动态品质同时提高单帧影像的信噪比 ,引入大幅提高辐射剂量的增强脉冲透视模式。文章介绍了这种工作模式下两种kV脉冲控制的非同步和同步X射线成像方法 ,以及它们的控制时序设计和性能分析
【Abstract】 The boost pulse fluoroscopy mode is introduced in mobile C-arm X-ray imaging systems. this mode is adopted a excessive X-ray dosage for satisfying the requirement of continuous dynamic image sampling and increasing the SNR of a single frame image. The kV control sequences of Non synchronization & synchronization X-ray generation are analyzed, and their waves are exhibited.
