Abstract: The present disclosure provides a spiral Computed Tomography (CT) device and a three-dimensional image reconstruction method. The spiral CT device includes: an inspection station configured to carry an object to be inspected, the inspection station defining an inspection space which is located above the inspection station and is used for accommodating the object to be inspected; a rotational supporting apparatus which is disposed around the inspection space in a plane parallel to a first direction and is rotatable around the inspection space in a detection state; a plurality of X-ray sources located on the rotational supporting apparatus and configured to transmit X-rays to pass through the inspection space; and a plurality of X-ray receiving apparatuses in one-to-one correspondence to the plurality of X-ray sources, the plurality of X-ray receiving apparatuses being located on the rotational supporting apparatus opposite to the plurality of X-ray sources respectively and configured to collect the X-rays passing through the inspection space, wherein the plurality of X-ray sources and the plurality of X-ray receiving apparatuses are rotational synchronously with the rotational supporting apparatus.
