摘要： A position sensor used in medical devices for use with medical positioning systems. The position sensor includes a core (80) having a body and one or more projections (841,842) extending from the body, wherein the core comprises a high-permeability material. The position sensor further includes a coil (74) surrounding the body, wherein the coil is configured to generate a voltage when subject to a magnetic field. The one or more projections extending from the body of the core are configured to concentrate the magnetic field into the coil and increase the voltage. Thus, various core designs are described which have projections which may increase the electrical and/or mechanical integrity of the position sensor and/or which may also induce magnetic flux flow within the position sensor thereby increasing the signals generated by the position sensor.

摘要： A method for registering a three dimensional (3D) coordinates system with a Medical Positioning System (MPS) coordinate system and with a two dimensional (2D) coordinate system, includes acquiring at least one 2D image of a volume of interest, the volume of interest including at least one tubular organ within the body of a patient. The 2D image is associated with the 2D coordinate system, and a plurality of MPS points is acquired, within the at least one tubular organ. The MPS points are associated with the MPS coordinate system, the MPS coordinate system being registered with the 2D coordinate system. A 3D image model is extracted of the at least one tubular organ form a pre-acquired 3D image of the volume of interest. A volumetric model of the at least one tubular organ from the 2D image is estimated and from the acquired MPS points, the 3D coordinate system is registered with the MPS coordinate system and with the 2D coordinate system by matching the extracted 3D image model and the estimated volumetric model of the at least one tubular organ.

摘要： Systems and methods are disclosed for navigating a surgical device toward a target organ in the body of a patient. An example method includes providing a surgical needle and a guide wire, the surgical needle configured for insertion into a vein or a beating heart. The method also includes holding the guide wire within the surgical needle while the surgical needle is inserted into the vein or the beating heart. The method also includes generating output in two modes, the output based on at least one medical positioning system (MPS) sensor on the guide wire, the output corresponding to a position of the surgical needle and the guide wire for navigating the surgical needle and the guide wire toward a target in the vein or the heart. The methods can be carried out directly by a physician or via a computer processor-based surgical system.
