Abstract:
A method for determining movement of a site in a patient, comprising the steps of:disposing one or more sensors respectively at location-invariant body parts of a patient;obtaining respective signals from said sensors and from said signals defining a patient-specific coordinate system, and displaying said patient-specific coordinate system in a first display presentation of a display monitor system;obtaining a substantially real-time image, in an image plane, of a region of said patient containing a moving site and displaying said image in a second display presentation of said display monitor system;identifying an orientation of said image plane in said patient-specific coordinate system and displaying a representation of said image plane with said orientation in said patient-specific coordinate system in said first display presentation; anddefining at least a point in said second display presentation which exhibits a motion path dependent on movement of said movement site, and displaying at least one characteristic point of said motion path in said image plane in said first display presentation.
