Abstract: Described herein are a computed tomography scanning system for inspecting an object and methods incorporating the same. The system includes an imaging assembly including a frame positioned within an underground chamber below a ground surface, a platform coupled to and translatable with respect to the frame, and a stage coupled to and rotatable with respect to the platform. The platform is translatable to raise the object above the ground surface and lower the object below the ground surface when the object is on the stage. The imaging assembly also includes an X-ray source fixed with respect to the frame and configured to emit radiation that is attenuated by the object as the platform translates and the stage rotates, and an X-ray detector fixed with respect to the frame, the X-ray detector configured to detect the radiation transmitted through the object and generate a signal representative of the transmitted radiation.

Abstract: Described herein is a high-energy x-ray imaging system including a stationary gantry, a conveyor assembly configured to convey an object to be imaged through the gantry, a plurality of linear accelerators, a detector array, and a control system. The linear accelerators are arranged in an array within the gantry and are configured to generate high-energy x-ray fan beams to be transmitted through the object. The detector array is positioned opposite the linear accelerators and is configured to collect the high-energy x-ray fan beams transmitted through the object. The control system is configured to energize the linear accelerators according to a predetermined control sequence to generate the high-energy x-ray fan beams, and construct a 3-D image of the object based on data received from the detector array and representative of the high-energy x-ray fan beams transmitted through the object.
