Tham khảo tài liệu 'novel applications of the uwb technologies part 11', kỹ thuật - công nghệ, cơ khí - chế tạo máy phục vụ nhu cầu học tập, nghiên cứu và làm việc hiệu quả | The Future of Ultra Wideband Systems in Medicine Orthopedic Surgical Navigation 287 Fig. 15. Wireless insulin pump manager Omnipod . Fig. 16. Wireless alcoholmeter Alcosystem . Fig. 17. Capsule Endoscopy Public Domain . Apart from ambulatory and personal medical devices wireless surgical tracking devices have also been developed to improve the accuracy and efficiency of diagnosis and surgery. Image guidance surgical navigation system uses optical and electromagnetic trackers to track the surgical instruments in the attempt to minimize the human error during surgery. Optical system Figure 18 uses two infrared cameras to triangulate the position of the target instrument. Figure 19 shows an electromagnetic tracking device developed by Ascension and GE healthcare. The system provides real time feedback of the current position of the biopsy needle as well as the needle path projection. 288 Novel Applications of the UWB Technologies Fig. 18. Optical tracking devices for surgical navigation Metronics . Fig. 19. The biopsy needle is coupled with electromagnetic tracking device to provide feedback of the needle positions Ascension . Healthcare . Current research The commercially available devices mentioned in previous section have undergone many years of research and development. The following section is going to look at some of the current researches being done with wireless medical device. While there are many wireless ambulatory monitoring systems mentioned above most of them operate in a standalone mode with its own receiver. It would be more beneficial to the physicians and health care professional to centralize all the information into one single device. Tia Gao et al. introduced a wireless sensor network WSN system for medical devices. Gao et al. 2008 The information from the sensors is wirelessly transmitted to the server and it can be accessed through handheld devices and computers Figure 20 . The authors tested the system along with medical .
