  • Publication number: 20240122568
    Abstract: An X-ray imaging system using multiple pulsed X-ray sources to perform highly efficient and ultrafast 3D radiography is presented. There are multiple pulsed X-ray sources mounted on a structure in motion to form an array of sources. The multiple X-ray sources move simultaneously relative to an object on a pre-defined arc track at a constant speed as a group. Electron beam inside each individual X-ray tube is deflected by magnetic or electrical field to move focal spot a small distance. When focal spot of an X-ray tube beam has a speed that is equal to group speed but with opposite moving direction, the X-ray source and X-ray flat panel detector are activated through an external exposure control unit so that source tube stay momentarily standstill equivalently. 3D scan can cover much wider sweep angle in much shorter time and image analysis can also be done in real-time.

  • Patent number: 11918403
    Abstract: System and method are disclosed for imaging acquisition from sparse partial scans of distributed wide angle. During real time image reconstruction, artificial intelligence (AI) determines if there is enough information to perform diagnostics based on initial scans. If there is enough information from the fractional scans, then data acquisition stops; if more information is needed, then system performs another round of wide-angle sparse scans in a new location progressively until a result is satisfactory. The system reduces X-ray dose on a patient and performs quicker X-ray scan at multiple pulsed source-in-motion tomosynthesis imaging system. The method and system also significantly reduce the amount of time required to display high quality three-dimensional tomosynthesis images.

  • Patent number: 11633104
    Abstract: Exemplary embodiments of systems and methods can be provided which can generate data associated with at least one portion of a sample. For example, at least one first radiation can be forwarded to the portion through at least one optical arrangement. At least one second radiation can be received from the portion which is based on the first radiation. Based on an interaction between the optical arrangement and the first radiation and/or the second radiation, the optical arrangement can have a first transfer function. Further, it is possible to forward at least one third radiation to the portion through such optical arrangement (or through another optical arrangement), and receive at least one fourth radiation from the portion which is based on the third radiation. Based on an interaction between the optical arrangement (or the other optical arrangement) and the third radiation and/or the fourth radiation, the optical arrangement (or the other optical arrangement) can have a second transfer function.

  • Publication number: 20220265879
    Abstract: The present disclosure discloses a discharge plasma disinfection device and method thereof. In the disinfection device, a gliding arc electrode pair generates the RNS-dominated reactive gas under the excitation of a gliding arc high-voltage power supply; and a dielectric barrier discharge electrode pair generates the ROS-dominated reactive gas under the excitation of a dielectric barrier discharge high-voltage power supply. These two reactive gases are introduced into a mixing chamber in a specific ratio and are subjected to an effective mixing reaction through an internal recycle system to obtain RNS/ROS mixed reactive gas in which reactive nitrogen species and reactive oxygen species coexist. The RNS/ROS mixed reactive gas may be directly configured to perform disinfection, and may also be configured to process an aqueous solution and then perform disinfection by the processed plasma-activated water.
