Title: SPIRAL CT DEVICE AND THREE-DIMENSIONAL IMAGE RECONSTRUCTION METHOD
Abstract:
A spiral CT device (100) and a three-dimensional image reconstruction method. The spiral CT device (100) comprises: an inspection platform (110) used for supporting an object to be inspected, the inspection platform (110) defining an inspection space (150) located thereon and used for accommodating the object to be inspected; a rotating support apparatus (120), in an inspection state, surrounding the inspection space (150) in a plane parallel to a first direction and capable of rotating around the inspection space (150); multiple x-ray sources (130) arranged on the rotating support apparatus (120) and used for transmitting X-rays passing through the inspection space (150); multiple X-ray receiving devices (140) corresponding one-to-one to the multiple X-ray sources (130), respectively arranged on the rotating support apparatus (120) opposite the multiple X-ray sources (130), and used for capturing X-ray signals passing through the inspection space (150), where the multiple X-ray sources (130) and the multiple X-ray receiving devices (140) can consistently rotate with the rotating support apparatus (120).
