摘要： An optical coupling is incorporated into an invasive device used in magnetic resonance (MR) imaging. The coupling is incorporated into the invasive device between an imaging or tracking RF coil, and the MR receiver. The optical coupling has a first transducer circuit coupled to the RF which converts between optical and electrical signals. An optical fiber is coupled to the first transducer circuit and extends out of the invasive device to medical imaging equipment. Near this equipment, a second transducer circuit converts optical signals to electrical, and electrical signals to optical, just opposite that of the first transducer circuit. The present invention thereby replaces long lead wires which can cause heating during MR imaging, and may distort an MR image.

摘要： An interactive surgery planning and display system mixes live video of external surfaces of the patient with interactive computer generated models of internal anatomy obtained from medical diagnostic imaging data of the patient. The computer images and the live video are coordinated and displayed to a surgeon in real-time during surgery allowing the surgeon to view internal and external structures and the relation between them simultaneously, and adjust his surgery accordingly. In an alternative embodiment, a normal anatomical model is also displayed as a guide in reconstructive surgery. Another embodiment employs three-dimensional viewing.

摘要： A tracking system monitors the position of a device within a subject and superimposes a graphic symbol on a diagnostic image of the subject. Registration of the tracked location with the diagnostic image is maintained in the presence of subject motion by monitoring subject motion and adjusting the display to compensate for subject motion. Motion monitoring can be performed with ultrasonic, optical or mechanical methods. The display can be adjusted by modifying the displayed location of the device or it can be adjusted by translating, rotating or distorting the diagnostic image.
摘要翻译： 跟踪系统监视对象内的设备的位置并将图形符号叠加在被摄体的诊断图像上。 通过监视对象运动并调整显示以补偿被摄体运动，通过诊断图像对被跟踪位置的注册保持在受试者运动的存在下。 运动监测可以用超声波，光学或机械方法进行。 可以通过修改显示的设备位置来调整显示，也可以通过翻译，旋转或扭曲诊断图像进行调整。
