With the increasing number of IGT applications and the availability of Ethernet in the IGT environment, standardization of information and communication technology is more important than ever ( 1). In addition to those standards in physical and transportation layers of device connections, Massachusetts General Hospital and the CIMIT are leading an initiative called Medical Device Plug-and-Play (MD PnP) to facilitate interoperability among a number of medical devices in the OR ( 9). CANOpen (EN 50 325-4) ( 7), which is an application layer for Controller-Area Network (CAN) (ISO 118 988) ( 8), has also been used. The ISO 11 073/IEEE 1073 Standard for Medical Device Communication ( 6) defines transportation profile (IEEE 1073.3.1) and physical layer (IEEE 1073.4.1) to allow plug-and-play operation for bedside device communication. There have been sporadic efforts to standardize the interconnections between medical devices and computers. In addition, with increasing research on robotic devices that support image-guided interventions, there has been a strong demand for communication standards among these devices and navigation software to allow sharing of information such as target positions, images and device status. This localization and image information is transferred from acquisition devices to navigation software for visualization and guidance. Today it is quite common to locate surgical tools relative to the patient’s body by using position and orientation tracking systems with optical ( 2), electromagnetic ( 3) or ultrasonic ( 4, 5) sensors, or to acquire images using real-time ultrasound, computed tomography or magnetic resonance imaging (MRI). Standardization of communication among devices and software in the operating room (OR) environment is a common issue in image-guided therapy (IGT) ( 1).
