Navigation with the Integration of Device Tracking and Medical Imaging

In image-guided therapy, both medical imaging and device-tracking systems are key components in providing the spatial relationship of a patient and surgical or interventional tools for accurate targeting. Both medical imagers and device-tracking systems need to be integrated and be used for different clinical applications. There are many medical imaging modalities available. Different imaging modality has its unique features in providing anatomical or functional imaging information for a particular application. Different device-tracking method also has its own advantages and weaknesses. In this chapter, different imaging modalities that can be used for procedure guidance are introduced, and their distinctive features on image guidance are discussed. Different device-tracking techniques and their characteristics for image guidance integration are described. The principle of navigation by integrating an imaging modality and a device-tracking modality is then explained. In the end, a few typical combinations of the imaging modality and device-tracking integrated navigation are discussed.
