A novel system is described which images in three dimensions, the total configuration of a colonoscope without the use of conventional radiological techniques. A low intensity magnetic field is used in conjunction with a miniature inductive sensor. The system intrinsically safe and it is potentially inexpensive and capable of being used in a normal hospital environment. Clinical trials are described in which the system is validated in terms of its suitability for the application. Magnetic and conventional X-ray images obtained ex vivo with the endoscope held in various configurations and comparisons in the patients confirm the practical applicability of the new system.
本文描述了一种新型系统，该系统无需使用传统放射技术即可对结肠镜的整体结构进行三维成像。低强度磁场与微型感应传感器配合使用。该系统本质安全，可能成本低廉，并且能够在普通医院环境中使用。文中介绍了临床试验，在试验中该系统在其应用适用性方面得到了验证。在内窥镜处于各种配置下离体获得的磁性图像和传统X射线图像以及在患者身上的比较证实了新系统的实际适用性。
