摘要： A system including an input sensor, a summer, a controller, and a feedback sensor. The input sensor: detects a first amount of force or torque applied on a component of an x-ray scanner gantry in a direction; and generates a command signal. The command signal indicates the first amount of force or torque. The summer generates an error signal based on the command signal and a feedback signal. The controller controls operation of a motor based on the error signal to: reduce the error signal; provide counterbalancing of the gantry in the direction; and provide a net force or torque on the gantry that is equal to a predetermined value or is within a predetermined range of the predetermined value. The feedback sensor detects a second amount of force or torque applied on the gantry in the direction as a result of the controlled operation and generates the feedback signal.

摘要： An electromagnetic device includes a jig and multiple wires. The jig includes a center member and coil-separating blocks. The coil-separating blocks 5 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.

摘要： A system and/or method is/are disclosed that may be used to plan a trajectory and/or placement of an instrument. The planning may be for placing an implant and/or positioning an instrument temporarily. When planning a procedure, the user may review a map, including an image, of the subject prior to performing the procedure. The image or map of the subject may illustrate locations of various features, such as a target for a procedure. Further, the map or image data may illustrate or be used to determine a possible entry point. In addition to features or portions of the subject that may be illustrated with the map, a display device may be used to illustrate limitations and boundaries relevant to the selected procedure. For example, a guide instrument may have a size and range of motion to guide an instrument for a procedure. The extent of the range of motion may be illustrated on the image or map to assist in planning, including finalizing or selecting, a trajectory, guide, and other portions of a procedure.

摘要： 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.

摘要： 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.
