Abstract:
1. A system to navigate an image-guided object comprising a tracking element and a transducer array configured to travel in an area of interest of an imaged subject in relation to an acquired image of the imaged subject, comprising: a four-dimensional (4D) imaging system comprising the image-guided object and configured to acquire first image data, the 4D imaging system further configured to use the first image data to create a 4D model representative of a time-dependent three-dimensional spatial model correlated to a time interval and defined in spatial relation and orientation relative to a first image coordinate system defined by a predetermined spatial relation and orientation of the first image data relative to the transducer array, wherein the time interval is one of a cardiac cycle or a respiratory cycle; a tracking system comprising sensors, the tracking system configured to track movement and orientation of the image-guided object through the imaged subject relative to a tracking coordinate system defined by the spatial relations and orientations of the sensors to the tracking element and to time; and a second imaging system different than the image-guided object, the second imaging system configured to acquire second image data, the second imaging system configured to use the second image data to create a three-dimensional (3D) model of the imaged subject correlated to a second image coordinate system defined by a spatial relation and orientation of the second image data correlated to a phase of the cardiac cycle or a phase of the respiratory cycle; a controller electrically connected in communication with the 4D imaging system, the second imaging system, and the tracking system, the controller having a processor configured to:
