Automatic registration of 3D camera recording to model for leads localization

The purpose of this research is to localize ECG electrodes from a 3D photo and to reduce electrode misplacement related errors in the ECG interpretation. A Kinect camera is used to take a 3D photo, which is registered automatically to a model derived from MRI/CT(MC). The registration algorithms use a sternum marker attached to the skin to enable an accurate and fast matching of the 3D photo and the MC model. The algorithms have been compared to optimal manual registration. For all cases the automatic registration algorithms performed much better than the manual registration. The automatic registration of a 3D photo with patient specific electrode positions will offer a novel way of preventing and correcting errors due to ECG lead misplacement.
