    Abstract: An X-ray tube housing with integrated cooling passages in the walls of the X-ray tube housing, through which a liquid or gas coolant is circulated and the heat is transferred from the X-ray tube housing to an external cooler. The integrated cooling passages are created around the perimeter of the X-ray tube housing as the X-ray tube housing is formed. For a rotating anode X-ray tube using an oil coolant, the path of heat transfer is from the anode to the glass insert and oil by the means of radiation. The oil that is in contact with the glass insert conducts heat away form the insert to the X-ray tube housing which is then cooled by the integrated cooling passages located within the X-ray tube housing through which fluid is passed to an external fluid cooling system.

    Abstract: Systems and methods for braking and releasing one or more pivot joints used in an X-ray positioning device are described. The systems and methods use a support arm that extends between a main assembly of the x-ray positioning device and an X-ray imaging assembly with an X-ray source and an X-ray detector that are disposed nearly opposite to each other. The support arm includes one or more pivot joints (such as horizontal, lateral, and/or orbital pivot joints) that allow the imaging assembly to move with respect to the main assembly. The pivot joints can each be connected to an automated braking system that is capable of selectively locking and unlocking a corresponding pivot joint, as indicated by a user-controlled switching mechanism. The braking systems containing multiple pivot joints can be individually controlled by separate switching mechanisms or simultaneously controlled by a single switching mechanism. Other embodiments are described.

    Abstract: Certain embodiments of the present invention relate to a collision detection system. The collision detection system includes a position indicator for determining an actual position of a component connected to the collision detection system. The system also includes an error calculator for determining a position error between the actual position and a selected position. The system further includes a comparator for comparing the position error to a position error limit. The comparator generates a halt signal based on the position error and position error limit. The system also includes a motion controller for controlling motion of the component. The motion controller stops motion of the component based on the halt signal. The comparator generates a halt signal when the position error is equal to or greater than the position error limit.
