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.

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: Disclosed is a system and method for tracking an instrument. The instrument may be tracked with one or more trackable members. The trackable members may be held relative to a handle to which the instrument is attached.

Abstract: A system for performing a medical procedure on a patient is provided. The system can include an imaging head defining a field of view relative to the patient. 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.

Abstract: Apparatus and methods are disclosed for use within an image-guided surgical navigation system for facilitating the combined positioning and orientation of multiple surgical implements. A tool guide having multiple cannulas is tracked by a surgical navigation system in real time. Position data of the tool guide is registered and combined with pre-acquired images by the navigation computer. Concurrent graphical representations of the plurality of cannulas are superimposed over the images and displayed. The display allows the surgeon to place the tool guide into the patient's body and position and orient the plurality of cannulas which are then used to place each of the implements.

Abstract: A tracking system can be used to track a plurality of tracking devices. A representation of at least two instruments may be displayed relative to image data. The representation is customizable to distinguish between the at least two instruments.

Abstract: A transformable imaging system configured to operate in at least two configurations. A first configuration may be open and a second configuration may be closed. The closed configuration may allow for imaging in along an arc greater than 180 degrees.

Abstract: A method and system is disclosed for acquiring image data of a subject. The image data can be collected with an imaging system in a selected manner and/or motion. More than one projection may be combined to generate and create a selected view of the subject.

Abstract: An array emitter including a plurality of emitting portions can be used to individually emit selected energy, such as x-ray radiation, from the emitter ray rather than powering or emitting radiation from all portions of the emitter array. According, providing a plurality of cells within an emitter array, and selectively emitting x-rays from individual cells can allow for selection of which cells to emit x-rays from to acquire selected image data. A process is disclosed for selecting, including automatically, which portions to power to emit energy.

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 at least two different energy characteristics. The image data can be reconstructed using reconstruction techniques.

Abstract: 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.

Abstract: A display may display a region of an anatomy that is not within the field of effect of an instrument. The additional views may assist in determining a location and orientation of an instrument. The instrument may be tracked with a tracking system to make the determination of image data to display.

Abstract: 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.

Abstract: A system including an x-ray scanner gantry having: a housing; a gantry gear; a rotor; a generator mounted on the rotor; and first and second generator gears connected to or engaged with one or more axles of the generator. The second generator gear is engaged with the gantry gear. A motor rotates the intermediate gear via a motor gear. A second actuator actuates the motor gear to engage the motor with the rotor. A control module operates in first and second modes and: while in the first mode, engages the intermediate gear to the first generator gear via the first actuator to rotate, via the motor gear, the intermediate gear and as a result the first generator gear; and while in the second mode, engage the motor to the rotor via the second actuator to rotate, via the motor gear, the rotor and as a result the second generator gear.

Abstract: Disclosed is a system for acquiring and using image data and generating a three-dimensional reconstruction of a subject. The three-dimensional reconstruction can be used to assist in determining various features, including axis and planes of a subject or members placed relative to the subject. The system can be implemented to plan and perform a procedure relative to the subject.
