| 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 |
| 20100249595 | SYSTEM AND METHOD FOR AUTOMATIC CALIBRATION OF TRACKED ULTRASOUND - A system and method of tracking ultrasound transducers or probes ( | 09-30-2010 |
| 20110082363 | METHOD AND SYSTEM FOR PERFORMING BIOPSIES - A method and system for performing biopsies can include an imaging system (190) for obtaining diagnostic images of a target region (200); a tracking system (100); a probe (75) having a deployable biopsy needle for performing a biopsy procedure where the tracking system generates tracking information for at least one of the probe and the biopsy needle; an ultrasound imaging system (50) for obtaining ultrasound imaging of the target region; and a computer (150) in communication with the tracking system, the imaging system and the ultrasound imaging system. The computer can register the tracking system with the imaging system. The computer transfers a marking (500) of a biopsy site associated with the biopsy procedure from the ultrasound imaging to the diagnostic images based on the tracking information and the registration of the tracking system with the diagnostic images. | 04-07-2011 |

| 20100268085 | INTERVENTIONAL NAVIGATION USING 3D CONTRAST-ENHANCED ULTRASOUND - A method for interventional navigation using 3D contrast-enhanced ultrasound (CEUS) imaging ( | 10-21-2010 |
| 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 |
