摘要： A system and method for identifying errors while tracking instrument navigations is enclosed. The method may include assigning a plurality of virtual points to a plurality of sensors. At least one of the virtual points may be a non-fixed virtual point. The assignment of virtual points to sensors may be determined based on the medical instrument, or the medical instrument attachment, being used. Virtual point locations may be determined for the non-fixed virtual point. The locations of the non-fixed virtual point may be determined based on the medical instrument, or the medical instrument attachment, being used. The vector values for vectors terminating at the non-fixed virtual point may be adjusted. The field integrity values for the virtual points may be computed. If a field integrity value is greater than a threshold value, an error signal may be communicated.

摘要： A system and method to image an imaged subject is provided. The system comprises a controller, and an imaging system including an imaging probe in communication with the controller. The imaging probe acquires image data with movement through the imaged subject. The system also includes an ablation catheter including a marker having a unique identifier to be detected in the acquired image data, and a tracking system having one of a plurality of tracking elements located at the imaging probe and at least another tracking element located at the ablation catheter. A display illustrates the image data acquired with the imaging probe in combination with a graphic representation of an imaging plane vector representative of a general direction of a field of view (FOV) of image acquisition of the imaging probe in spatial relation to a graphic representation of the identifier and the location of the ablation catheter.
