A subject-specific technique for respiratory motion correction in image-guided cardiac catheterisation procedures

Image-guided minimally-invasive cardiac interventions have the potential to greatly improve treatment for heart disease by providing a cardiac 'roadmap' as guidance for cardiologists. However, the techniques have yet to be widely translated to the clinic due to alignment errors between the roadmap and the anatomy. One of the main reasons for these errors is breathing motion. This paper described the novel techniques for subject-specific modelling and estimation of breathing motion that enabled, for the first time, demonstration of a personalised breathing roadmap in such interventions. The technique has since been incorporated into a commercial prototype system (Philips EP Navigator).
