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 method and system for identifying an implant in an x-ray image of an anatomy shown on a display screen. The method includes: displaying the image including an artifact of the implant; prompting a user to enter parameters of the implant; displaying a rendering of the implant over the image; prompting the user to position the rendering on the artifact at an accurate position corresponding to an actual position of the implant; alerting the user when the rendering is at an inaccurate position; prompting the user to reposition the rendering from the inaccurate position to the accurate position; alerting the user when the rendering is maneuvered by the user to the accurate position; and after the rendering has been maneuvered to the accurate position by the user, reconstructing the x-ray image to replace the artifact with the rendering affixed in the accurate position.

Abstract: Systems, methods, and devices for reconstructing an image is provided. An imaging device may be oriented at one or more poses and an image may be received at each of the one or more poses to form a set of images. Pose information may be received at each of the one or more poses. The set of images and the pose information may be inputted into a reconstruction model to generate a three-dimensional representation of the one or more anatomical elements.

Abstract: Devices, systems, and methods used to register medical image data with anatomical positions are disclosed. The image data is captured by an imaging system over a period of time. The positions are determined by a tracking system over the period of time. The positions are averaged to determine an average position of the anatomy, which is then used for registration of the image data with the anatomy. Registration based on the average position can then be used to enhance the quality of 3D images of the anatomy, as well as to improve navigation for a surgical procedure.

Abstract: 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.

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.

Abstract: 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.

Abstract: Devices, systems, and methods used to register medical image data with anatomical positions are disclosed. The image data is captured by an imaging system over a period of time. The positions are determined by one or more modalities over the period of time. The positions are collected into position data, and determinations are made as to which position data is best for registering the image data with patient anatomy and for reconstructing 3D images of the patient anatomy.

Abstract: Laser ablation devices and related systems and methods may have laser outputs with multiple wavelengths. Laser ablation devices may include a laser energy source that can emit two or more laser outputs with different wavelengths. Some laser ablation devices include a processor to control the laser energy source to cause the laser energy source to emit a target wavelength blend with the laser outputs.

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: 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: Devices and systems used to ablate tissue of a tumor using laser energy are disclosed. The devices and systems include a laser probe and a magnetic resonance (MR) safe temperature probe. The MR safe temperature probe includes an optical sensor. A bone anchor fixture separates the laser probe and the MR safe temperature probe to prevent interference in the MR safe temperature probe data. Proton Resonance Frequency (PRF) thermometry is used to model a temperature of a pixel of an MR image located adjacent the optical sensor. The modeled pixel temperature and the measured temperature are compared and monitored. Exceeding a threshold difference value causes an intervening action to occur.

Abstract: Disclosed is a system and method for operating an imaging system. The imaging system may move or be moved to acquire image data of a subject at different positions relative to the subject. The image data may, thereafter, be combined to form a single image.

Abstract: Disclosed is a method to remove distortion from a navigation system. The navigation system may be used to perform a procedure on a subject. The procedure may be any appropriate procedure. The navigation system may be used to account for the distortive effects of various conductive objects positioned near the subject on which the procedure is performed.

Abstract: A system or method according to at least one embodiment of the present disclosure includes receiving a preoperative image of a patient in a first posture; receiving an intraoperative image of the patient in a second posture; comparing the preoperative image of the patient in the first posture with the intraoperative image of the patient in the second posture; and determining, based on comparing the preoperative image of the patient in the first posture with the intraoperative image of the patient in the second posture, a difference between the first posture and the second posture, the adequate surgical changes are imparted to the second posture to achieve satisfactory surgical outcome.
