如果可能的话，许多神经外科医生更喜欢使用术中计算机断层扫描（CT）来检查是否存在残留病灶或意外出血。我们报告了一种实用的术中 CT 成像系统，该系统使用安装在手术室中的高速 CT 扫描仪以及数控神经外科手术台。我们设计了一个轨道系统来移动 CT 龙门架。龙门架固定在机动载体上，可在嵌入地板的轨道上平稳移动，从房间墙壁到手术台的最大范围为 2.85 m。操作台的纵向运动可通过脚踏开关轻松调节，从手动控制直接从 CT 扫描仪的计算机直接控制到自动控制，就像普通 CT 扫描床一样，在 CT 扫描期间以 2、5 或 10 毫米的增量进行调节。使用碳制成的射线可透头架或碳制成的头板作为头枕。使用该CT扫描系统，对46例脑肿瘤、颈部病变或其他颅内病变患者进行了术前和术中CT扫描。我们可以在移动CT机架和显微神经外科手术台之间有足够的工作空间对患者进行手术。我们可以在手术伤口保持开放、手术单保持原位、手术体位不变的情况下，在手术台上对患者进行术中CT成像，从而节省了术中CT扫描的时间以及需要时为进一步手术做准备的时间。这种安装在手术室的术中CT成像系统应该对神经外科有用。
Many neurosurgeons prefer to use intraoperative computed tomographic (CT) scanning, when possible, to check whether there is residual lesion or unexpected bleeding. We report a practical intraoperative CT imaging system using a high-speed CT scanner installed in the operating room along with a digitally controlled neurosurgical operating table. We designed a rail-track system to mobilize the CT gantry. The gantry is fixed onto a motorized carrier that can be moved smoothly on a rail-track embedded in the floor and with a maximum reach of 2.85 m from the room's wall to the operating table. The longitudinal motion of the operating table is easily adjusted by a foot switch from manual control to automatic control directly from the CT scanner's computer like an ordinary CT scanner bed in increments of 2, 5 or 10 mm during CT scanning. Either a carbon-made radiolucent head frame or carbon-made head plate is used as a headrest. Using this CT scanner system, pre- and intraoperative CT scannings were performed on 46 patients with brain tumors, cervical lesions or other intracranial lesions. We could operate on the patient with enough working space between the mobile CT gantry and the operating table for microneurosurgery. We could obtain intraoperative CT imaging of a patient on the operating table while the surgical wound remained open, the surgical drapes kept in place, and the surgical position unchanged, saving time in intraoperative CT scanning and preparation for further surgery when needed. This intraoperative CT imaging system installed in the operating room should be useful for neurosurgery.
