摘要： An x-ray source can include an x-ray tube and a power supply. The x-ray tube can be removably affixed to the power supply in a rigid manner with the x-ray tube movable and holdable along with the power supply when affixed thereto. A releasable coupling between the x-ray tube and the power supply can create an interface defining a potential arc path. A means, such as a non-linear plug and socket junction, a gasket, or an electrically conductive sleeve, can be used for resisting arcing along the potential arc path.

摘要： An inverter circuit allowing a single drive circuit to perform both tracking control for tracking resonance frequency fluctuations caused by load fluctuations, and power control, thereby reducing switching loss. An inverter drive circuit part obtains a phase difference between output current and output voltage directed to a load circuit connected to a midpoint of two arm circuits of the inverter circuit, and controls a phase of the driving signal directed to each semiconductor switch such that the phase difference becomes zero or a predetermined value, enabling an operating frequency of the inverter circuit part to track a resonance frequency of the load circuit, and enabling a current phase to be delayed with respect to a voltage phase, thereby achieving ZCS. Since the phase difference is used, an auxiliary circuit is not necessary for measuring a current value in proximity to the semiconductor switches.

摘要： Improved methods and apparatuses for inserting pedicle screws in accordance with embodiments of the present invention include an image correction algorithm. In various embodiments, an original image of a region of interest of a patient including a pedicle is created with an X-ray emitter and an X-ray detector. Due to the X-ray emitter not being aligned orthogonal to the X-ray detector, the original image will be skewed. Using a known location and orientation of the X-ray detector, a location and orientation of the X-ray emitter provided by a position monitoring system, and the original image, a processing system can execute the image correction algorithm to provide a corrected image to allow a surgeon to properly insert a pedicle screw along the axis of the pedicle while viewing an accurate corrected image in real time.
