20100168556 | SYSTEM FOR LOCAL ERROR COMPENSATION IN ELECTROMAGNETIC TRACKING SYSTEMS - A system for local metal distortion correction for using an accurate electromagnetic tracking system in a medical environment is disclosed containing an electromagnetic field generator monitoring a medical device having a suitable sensor coil wherein a correction function, derived from an error correction tool, is applied to the position and orientation readings of the sensor coil. The error correction tool consists of a number of electromagnetic sensors arranged in a fixed and known geometric configuration and is placed surrounding the site of the medical procedure. Sensor data is displayed on an imaging system. In addition, a distortion mapping can be done utilizing optical sensors for relative positioning readings along with an electromagnetic tracking system sensor. | 07-01-2010 |

20110015628 | ADVANCED ABLATION PLANNING - In planning an ablation procedure, a planned target volume (PTV) is imported, which is typically selected by a doctor but may be computer-identified. An ablation solution comprising a plurality of ablation volumes is generated or selected using a lookup table. Ablations sharing a common axis along a line of insertion are grouped into blocks. Alternatively, the PTV is enveloped in a sphere, and a pre-computed ablation solution (e.g., a 6- or 14-sphere solution) is identified to cover the PTV sphere. Optionally, a mathematical algorithm is executed to increase an axis through the ablation spheres to generate ellipsoidal ablation volumes that envelop the PTV. | 01-20-2011 |

20150043794 | MULTI-MODALITY DEFORMABLE REGISTRATION - A method, system, and computer program product are provided for performing a multi-modal deformable imaging registration between two different modalities for which a functional dependency is missing or very difficult to identify. The method provides a nonlinear mapping between every pair of points in the two image modalities by calculating the nonlinear mapping for only a limited number of identifiable landmarks within the two modalities and a statistical deformation model of the structure of interest. The method comprises: calculating a mean deformation and a plurality of deformation mode Eigen vectors for a body structure from images from the same imaging mode with different deformation states for a plurality of subjects; performing a registration of a limited number of uniquely identifiable landmark points between images from two different imaging modalities for the same subject to calculate the deformation field for the landmarks from the images; determining weights for each deformation mode Eigen vector using deformation field values at the landmarks with the mean deformation and the deformation mode vectors; and summing the mean deformation field and the linear combination of the weighted deformation mode vectors to determine the deformation field between the different imaging modes for all the points within the images. | 02-12-2015 |
