Abstract

The present invention is directed to systems and methods for imaging during medical procedures and to apparatus and methods for making and using catheters including positional sensors for imaging systems for such procedures. The system is provided for facilitating imaging a patient during a medical procedure that includes an electromagnetic field generator for generating an electromagnetic field around a desired region of a patient's body to provide an external reference frame; an elongate member comprising a proximal end, a distal end sized for introduction into the patient's body, and a distal portion carrying a plurality of sensors spaced apart from one another such that the sensors may be positioned within the patient's body; and a processor for receiving signals from the sensors generated in response to the electromagnetic field, the processor configured to identify when the plurality of sensors move relative to the external reference frame to identify corresponding movement of the patient's body.
