Book excerpt: Image-guided therapy is a recently developed field that combines the use of computer technology with tracked surgical tools and pre-operative or intra-operative images for planning, guiding, and performing diagnoses and surgical interventions in a minimally invasive manner. It has been used in neurosurgery, orthopaedics, otolaryngology, and plastic and cranio-facial surgeries to improve patient safety and health-care outcomes. This technology relies upon a set of complex subsystems to perform tasks such as optical and electromagnetic 3D tracking, ultrasound imaging, endoscopy, and overall navigation, yet they have not been well characterised in this regard. This work presents methods and results for calibration and error analysis of these subsystems, and presents solutions to issues that impede their use for practical and intuitive real-time navigation and guidance in the operating room.
