Abstract
The present invention provides an X-ray transceiving component for a CT imaging apparatus, comprising one or more bulb devices and a plurality of detector devices. The one or more bulb devices are configured to emit quadrate-tapered or fan-shaped X-ray beams. The plurality of detector devices are configure to receive the quadrate-tapered or fan-shaped X-ray beams emitted by the one or more bulb devices, each of the quadrate-tapered or fan-shaped X-ray beams comprising X-rays passing through a scanning field of view. Note that the plurality of detector devices are configured to receive X-rays passing through different areas within the scanning field of view, the one or more bulb devices are micro-focus bulb devices, and the plurality of detector devices are flat panel detectors or photoelectric coupling detectors. The present invention can greatly improve a resolution of CT imaging, increase imaging efficiency, and realize low-dose diagnosis in the case of ensuring that the scanning field of view is sufficient.
