  • Publication number: 20240161996
    Abstract: Various methods and systems are provided for an x-ray imaging system. In one example, a method for decelerating a rotor of an x-ray tube of an imaging system includes controlling and/or monitoring a speed and position of the rotor, passing the rotor through a first position where a force exerted on the rotor, is less than Earth's gravitational pull, the force due to a combination of gravity and radial acceleration, and initiating a predefined deceleration profile to decelerate the rotor to a halt when the x-ray tube passes through the first position.

  • Patent number: 11591590
    Abstract: The present disclosure relates to the generation of an activated platelet product in which one or more of the presence or absence of clots, the timing of clot formation (if present), and/or the mechanical strength of clots (if present) is controlled by the presence or concentration of calcium ions during the activation process. In certain embodiments, the calcium ion concentration is controlled in the presence of pulsed electric fields or a chemical activator (e.g., thrombin) as part of the activation process.
