Spiral CT

Spiral CT breaks through the traditional CT design. It adopts slip ring technology, which connects the power cable and some signal wires to different metal rings in the fixed frame. The X-ray tube and detector sliding brushes are connected to the metal ring. The tube and the detector are not limited by the cable length. They rotate continuously and uniformly along the long axis of the human body, and the scanning bed advances synchronously and uniformly (the traditional CT scanning bed is stationary during scanning). The scanning trajectory advances spirally, which can be fast and uninterrupted. Complete the volume scan.
