A method and apparatus for identifying a member used in a navigation system. The navigation system can determine the identification of an instrument via an input. The input can be substantially automatic when an instrument is introduced into the navigation system field or assembly.

Automatic identification of tracked surgical devices using an electromagnetic localization system

A system and method for operating an assembly, such as a powered drill assembly. The assembly may be operated to provide feedback to the user regarding a selected position and/or condition of the powered drill system. The powered drill system may be used to power or drive a selected tool, such as a resection or grinding tool.

Powered drill assembly

In various specific embodiments, a localizer can include a plurality of coil groups, where each coil group includes three coils that are formed around a single center. Each of the three coils can be formed around separate jigs and the jigs can be interconnected to form the coil group. The jigs need not be annular, but may be formed in any appropriate configuration of shape or geometry for forming the final coil group.

Modular coil assembly

Systems and methods for monitoring one or more anatomical elements are provided. An image depicting one or more anatomical elements and a plurality of annotations may be received. The image may comprise a plurality of image elements. Each annotation may correspond to one of the one or more anatomical elements and may be associated with one of the plurality of image elements. Movement information about movement of at least a portion of a particular anatomical element may be received. Image elements corresponding to the particular anatomical element may be identified to yield a set of image elements. The set of image elements may be adjusted based on the movement information to yield an updated image reflecting changes to affected anatomical elements.

Systems and methods for monitoring one or more anatomical elements

Systems and methods for correcting experienced EM fields measured at each of one or more EM trackers of an EM tracking system as such measurements are influenced by a known distorter are disclosed herein. An EM emitter may transmit an EM field such that it contains the one or more EM trackers. The system then determines a pose of a distorter within the EM field. The system receives, from each EM tracker, data representing experienced EM fields as distorted by a distortion field caused by the distorter. The system proceeds to determine the distortion field using the pose and a model comprising one or more characteristics of the distorter. The system may first optimize the model. The system calculates data representing corresponding corrected experienced EM fields based on each respective experienced EM field and the determined distortion field at the same location.

Electromagnetic distortion corrections for known distorters

A system and method for a procedure that can be performed on an appropriate subject. Procedures can include assembling any appropriate work piece or installing members into a work piece, such as an airframe, autoframe, etc. Regardless of the subject, generally the procedure can have a selected result that is efficacious. The efficacious result may be the desired placement of a device. The system and method can be used in confirming an efficacious result.

Method and apparatus for image-based navigation

Disclosed is a system and method for operating an assembly, such as a powered drill assembly. The assembly may be operated to provide feedback to the user regarding a selected position and/or condition of the powered drill system. The powered drill system may be used to power or drive a selected tool, such as a resection or grinding tool.

System and method to control operation of a drill

Systems and methods for performing registration between a patient space and an image space are disclosed herein. Systems using such methods may identify a pose of a registration frame having one or more apertures within the patient space using a tracking system. Image data corresponding to the image space having an image of the registration frame is taken. A plurality of aperture locations within the image data (corresponding to the apertures of the registration frame) are identified in the image data. Aperture representations from a model of the registration frame are matched to these aperture locations to determine a pose of the registration frame within the image space. A transform between the patient space and the image space is generated based on the pose of the registration frame within the patient space and the pose of the registration frame within the image space. Optimization methods for this transform are discussed.

Systems and methods for registration between patient space and image space using registration frame apertures

An electromagnetic device includes a jig and multiple wires. The jig includes a center member and coil-separating blocks. The coil-separating blocks protrude from the center member and are separated from each other to provide a coil channels. Each of the wires is wrapped on the jig, around the center member, and in one of the coil channels to form one of a multiple coils. Each of the coils is configured to connect to an electromagnetic navigation system and generate respective electromagnetic fields to be emitted relative to a subject.

Electromagnetic coil apparatuses for surgical navigation and corresponding methods

Disclosed is a surgical navigation system for tracking an instrument relative to a patient. The system can track a portion of the patient, an instrument, and/or both relative to image data, a coordinate system, an atlas, a morphed atlas, or combinations thereof. The system can include a tracking device on the instrument to provide six degree of freedom information regarding the location of the instrument.

Method and apparatus for surgical navigation

Disclosed is a method and system for navigating an instrument relative to a patient that can be near a field distorting feature. A localizer can generate an electromagnetic field that is sensed by a tracking device to determine a location of the tracking device with the sensed electromagnetic field. The system and related method can assist in determining whether a navigation field is distorted near a tracking device of the instrument.

Navigation field distortion detection

A system for tracking a navigated instrument. The system can include a first elongated instrument and a second elongated instrument. The first elongated instrument can have a first proximal end and a first distal end. The first elongated instrument can be adapted to be positioned relative to an anatomy. The second elongated instrument can move adjacent to the first elongated instrument. The second elongated instrument can have a second proximal end and a second distal end. The system can also include at least one tracking device coupled to the second elongated instrument. When the second elongated instrument is in a first position, the at least one tracking device tracks the first distal end of the first elongated instrument, and when the second elongated instrument is in a second position, the at least one tracking device tracks the second distal end of the second elongated instrument.
