20140018662 | POSITION AND ORIENTATION ALGORITHM FOR A SINGLE AXIS SENSOR - A method includes generating a magnetic field in a predefined volume. A reference model is defined, which models the magnetic field at multiple points in the volume using spherical harmonics. The magnetic field is measured by a field detector, which is coupled to an intra-body probe inserted into an organ of a living body located in the volume. A cost function is defined by comparing the measured magnetic field with the reference magnetic field model within the volume. The cost function is minimized by a computation over dipole terms in a derivative over the cost function so as to find a position and orientation that matches the measured magnetic field. The found position and orientation is outputted as the position and orientation of the probe in the organ. | 01-16-2014 |
20150176961 | ADAPTIVE FLUOROSCOPE LOCATION FOR THE APPLICATION OF FIELD COMPENSATION - Compensation for a field-perturbing element in a magnetic tracking system for locating a probe is achieved by creating a reaction field model while the field-perturbing element is in known positions. A magnetic field location sensor is disposed between the field-perturbing element and magnetic field generators of the tracking system. Magnetic field readings from the location sensor and from a magnetic field sensor on the probe are taken while the field-perturbing element is present. The position of the field-perturbing element is estimated from the location sensor readings, and a predicted reaction field calculated from the reaction field model. A compensated measurement is obtained by subtracting the predicted reaction field from the field detected by the location sensor. The readings from the probe sensor are adjusted using the compensated measurement in order to calculate the true position of the probe. | 06-25-2015 |
