Abstract: A stand-alone MR or hybrid PET-MR imaging system incorporating a surface stationary RF coil structure is disclosed. The imaging system includes a support assembly comprising a cradle to accommodate a subject and a bridge to receive the cradle and provide for translation therealong to enable an acquisition of imaging data. An RF coil structure is positioned between the bridge and the cradle, and includes a base portion, a cover portion, and an array of RF coil elements positioned on the cover portion. The cover portion includes contoured features that enable placement of RF coil elements in proximity to a subject and to provide a constant and uniform gap between the RF elements and the cradle. The RF coil structure also includes structural elements that support the cradle when rolling over the array of RF coil elements without deforming the RF coil elements.

Abstract: A structure and method of operation of a journal bearing is disclosed that minimizes contact of the shaft with the sleeve during start up and slow down of rotation of the shaft relative to the sleeve, or vice versa. The bearing assembly includes a gravitational load reduction mechanism with magnets disposed on the sleeve and on the shaft in alignment with one another. The magnet(s) on the shaft interacts with the magnet(s) disposed on the sleeve to provide a force against the pressure of the shaft towards the sleeve generated by gravity on the rotating component. The magnets enable centering of the rotating component within the stationary component during low rotation and non-rotation. This prevents rubbing of the rotating journal bearing component surfaces, e.g., sleeve, against the stationary journal bearing component, e.g., shaft, during assembly, ramp-up, and coast-down when the journal bearing fluid provides minimal or no bearing centering capability.

Abstract: In the present invention, a connector pin assembly for a high voltage (hv) connector used to connect a high voltage (hv) power supply to a cathode assemble of an X-ray tube is provided. The pin connector assembly includes a conductive outer cylinder adapted to be connected to a hv power supply, a conductive inner cylinder located at least partially within the outer cylinder, a biasing member disposed within the inner cylinder, a conductive plunger slidably disposed within and engaged with the inner cylinder and the biasing member and a non-conductive member disposed within the inner cylinder, the non-conductive member operable to restrict a current flowing through the connector pin along a path from the outer cylinder through the inner cylinder to the plunger, without contacting the biasing member.
