摘要： A coordinate system calibration jig that includes radiopaque elements arranged in a fixed predetermined pattern and configured, in response to the radiopaque elements generating a fluoroscopic image, to define a position of the jig in a fluoroscopic coordinate system of reference. The jig further including one or more connectors configured to receive magnetic sensors in respective predetermined fixed locations and orientations with respect to the jig, so that signals from the magnetic sensors in response to a magnetic field traversing the sensors characterize the position of the jig in a magnetic coordinate system of reference defined by the magnetic field.

摘要： A magnetic field pad location system is provided with dual elongated field generation pads with self-tracking. Each pad comprises magnetic coils operable to generate magnetic fields. The pads include a mechanism for securing the two pads in place on a patient table to prevent movement of the pads. A processor executes a process for installation of the two pads, comprising correlation of the magnetic fields generated by the coils to define a reference magnetic field for sensing. In one embodiment, each pad includes a same number of magnetic coils in each spatial direction. In one embodiment, the magnetic coils are tri-axial coils placed at corners of the pads. In another embodiment, each pad includes an array of six single coils.

摘要： A system includes multiple electrically-conductive channels and a processor. The processor is configured to receive, over the electrically-conductive channels, (i) respective first electric currents from a probe, which is within a body of a patient, via a plurality of first electrodes, which are attached to skin of the patient at a region of the body, and (ii) a second electric current from the probe via a second electrode, which is attached to the skin and is connected to one of the channels. The processor is further configured to ascertain respective first electric-current values of the first electric currents and a second electric-current value of the second electric current, and to calculate a position of the probe between the region and the second electrode, based on the first electric-current values and the second electric-current value. Other embodiments are also described.
