Systems and methods for tracking positions between imaging modalities and transforming a displayed three-dimensional image corresponding to a position and orientation of a probe

摘要

Systems and methods are provided for transforming a displayed three-dimensional image corresponding to a position and orientation of a field of view of an imaging probe. A three dimensional image of a tissue in a first co-ordinate space can be displayed. A field of view of an imaging probe in a second co-ordinate space can be configured, where the imaging probe has a plurality of transmitters removably connected to it, the transmitters operable to determine the position and orientation of the field of view relative to the positions of the transmitters in the second co-ordinate space. The first and second co-ordinate spaces can be co-registered, and the position and orientation of the field of view in the second co-ordinate space can be transformed to the first co-ordinate space. The three-dimensional image can be displayed to correspond to the transformed position and orientation of the field of view.

1. A method for calibrating a field of view of an imaging probe relative to a plurality of transmitters removably connected to the imaging probe, the method comprising:
positioning an end of a configuration tool at a plurality of configuration positions on a transducer of the imaging probe, the configuration tool having at least one transmitter; recording a location of the configuration tool at each of the plurality of configuration positions; and determining a calibration matrix based on the recorded location of the configuration tool at each of the plurality of configuration positions, without using image information from the imaging probe, wherein the calibration matrix relates a transducer co-ordinate frame to a transmitter coordinate frame, and wherein the transducer co-ordinate frame has an origin (O) at a center of a face of the transducer, the origin determined from the recorded location of the configuration tool at each of the plurality of configuration positions.
