A technically successful biopsy or drainage procedure performed with computed tomographic (CT) guidance depends on two essential elements: determination of the correct entry point on the patient and placement of the biopsy needle or trocar drainage catheter along a predetermined track. A hand-held guidance device was used in conjunction with the lighting system on the CT scanner and measurements obtained from CT images to achieve this goal in 40 patients. The approach minimized trauma to the patient and decreased the time required for CT.
在计算机断层扫描（CT）引导下进行的技术上成功的活检或引流手术取决于两个基本要素：确定患者身上的正确进针点以及沿着预定路径放置活检针或套管引流导管。在40例患者中，使用了一种手持引导装置结合CT扫描仪上的照明系统以及从CT图像获得的测量数据来实现这一目标。该方法将对患者的创伤降至最低，并减少了CT所需的时间。
