Abstract: An imaging device for obtaining 360-degree images of an anatomical feature of a patient or of another object includes an open ring having a first end, a second end, and an axis, the open ring defining an outer arc and an inner arc; a support arm configured to support the open ring and to rotate the open ring about the axis; a track extending along the open ring; a source movably disposed on the track and operable to generate signals useful for imaging; and a detector movably disposed on the track, the detector operable to detect signals generated by the source. Movement of the source and detector along the track, coupled with rotation of the open ring about the axis, enables the source and detector to travel at least 360 degrees about the axis.

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.

Abstract: 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.

Abstract: A method and system is disclosed for acquiring image data of a subject. The image data can be collected with an imaging system with a selected filtering characteristic. The image data can be reconstructed using reconstruction techniques.

Abstract: 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.

Abstract: A system and method to analyze image data. The image data may be used to assist in determine the presence of a feature in the image. The feature may include a bubble.

Abstract: A system and a method are disclosed that allow for generation of a model or reconstruction of a model of a subject based upon acquired image data. The image data can be acquired in a substantially mobile system that can be moved relative to a subject to allow for image acquisition from a plurality of orientations relative to the subject. The plurality of orientations can include a first and final orientation and a predetermined path along which an image data collector or detector can move to acquire an appropriate image data set to allow for the model of construction.

Abstract: A system including a thermal sensor with an instrument placed in a volume. The thermal sensor may be useful in determining a temperature at a surface of the instrument and a distance away from the instrument. A therapy may be performed based on a sensed temperature with the thermal sensors.

Abstract: A system and apparatus is disclosed to automatically determine the identification and selected information relating to instruments. The identification information may be read or determined by various reader systems and then transferred for various purposes. The identification information may be stored on the instrument with a storage system or printing and/or recalled from a memory once the identification is made.

Abstract: Disclosed is a system for assisting in guiding and performing a procedure on a subject. The subject may be any appropriate subject such as inanimate object and/or an animate object. The guide and system may include various manipulable or movable members, such as robotic systems, and may be registered to selected coordinate systems.

Abstract: Selected artifacts, which may be based on distortions or selected attenuation features, may be reduced or removed from a reconstructed image. Various artifacts may occur due to the presence of a metal object in a field of view. The metal object may be identified and removed from a data that is used to generate a reconstruction.

Abstract: 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.

Abstract: Disclosed is a method and system for performing a procedure. The system may include a navigation system and/or a surgical robot to be used to at least assist in the procedure. The system may assist in delineating objects and/or determining physical characteristics of subject portions. The system may assist in performing and/or a workflow of the procedure.

Abstract: A method and system is disclosed for acquiring image data of a subject. The image data can be collected with an imaging system using various selection techniques. The selection techniques may be used to assist in generating selected images for viewing. Selection techniques may include moving a filter to filter a selected portion of an imaging beam.

Abstract: A system including initialization, imaging, alignment, processing, and setting modules. The initialization module obtains patient parameters for a patient and procedure and surgeon parameters. The initialization module selects first settings for an x-ray source based on the patient, procedure, and surgeon parameters. The image module obtains a first sample set of images of a region-of-interest of the patient and a master sample set of images. The first sample set was acquired as a result of the x-ray source operating according to the first settings. The alignment module aligns the first sample set to the master sample set. The processing module processes pixel data corresponding to a result of the alignment based on a pixel parameter or one of the patient parameters. The setting module adjusts the first settings to provide updated settings. X-ray dosage associated with the updated settings is less than x-ray dosage associated with the first settings.

The imaging head can include at least one transmitter that emits at least one signal in the field of view, and at least one receiver that receives at least one reflected signal from the field of view. The at least one reflected signal received can be based on at least one electrical property of at least one material in the field of view. The system can further include a workstation, which can determine, based on the at least one reflected signal received by the at least one receiver, a location of at least one boundary of the material within the field of view. The system can include a display that displays an image of the location of the at least one boundary.
