Abstract: Disclosed are a high-speed real-time bus system and a data processing method thereof. Each node device forms an annularly connected topological structure by means of a high-speed real-time bus; a master node device respectively sends a bus clock signal and a data signal to a slave node device of the next grade of the master node device in the topological structure by means of a clock channel and a data channel; each slave node device receives the bus clock signal and the data signal sent from the respective node device of the previous grade, performs data processing according to the bus clock signal and the data signal so as to update the data signal and sends the bus clock signal and the updated data signal to the respective node device of the next grade.

Abstract: Provided are a scanning-type X-ray source and an imaging system therefor. The scanning-type X-ray source comprises a vacuum cavity (1), wherein a cathode (2) and a plurality of anode target structures (3) are arranged in the vacuum cavity (1); a gate electrode (4) is arranged in a position, close to the cathode (2), in the vacuum cavity (1); a focusing electrode (5) is arranged in a position, close to the gate electrode (4), in the vacuum cavity (1); and a deflection coil (6) is arranged in a position, close to the gate electrode (4), at the outer periphery of the vacuum cavity (1). The scanning-type X-ray source generates electron beams by using cathode (2), controls the powering-on/off of the electron beams by the gate electrode (4), and the deflection coil (6) controls the direction of motion of the electron beams, so as to complete the switching between multiple focuses.

Abstract: A multi-energy static security CT system comprises at least one N-stage image chain structure (5) and a baggage conveying belt (4) provided at an inner side at the bottom of the N-stage image chain structure (5). The N-stage image chain structure (5) and the baggage conveying belt (4) are fixed at a pre-configured positions by means of a machine frame (8). The N-stage image chain structures (5) are sequentially arranged in a forward direction of a baggage channel, and adjacent N-stage image chain structures (5) are offset relative to each other. By exposing radiation sources in the N-stage image chain structure (5) at different times, the static security CT system generates an image having a higher temporal resolution and more energy spectrum levels than an image generated by a spiral CT system. Also provided is an imaging method implemented by means of the static security CT system.
