1概述PICKERIQxtraCT机中X线系统是通过控制扫描参数产生获得病人图像所必须的X射线。X线系统的核心控制部分是X线系统控制板(XSC),XSC板通过控制高压发生器的高压(kV)、电流(mA)和曝光时间(time)参数来控制X射线的产生,同时接收来自高压发生器的kV和mA反馈信号,并对kV和mA分别 1 Overview The X-ray system in the PICKERIQxtraCT machine generates the X-rays necessary to obtain a patient’s image by controlling the scanning parameters. The core control section of the X-ray system is the X-ray System Control Board (XSC), which controls the generation of X-rays by controlling the high voltage (kV), current (mA), and exposure time parameters of the high voltage generator while receiving KV and mA feedback signals from high voltage generator, and kV and mA, respectively
