ABSTRACT:
A dynamic computed tomographic X-ray scanner concurrently translates and rotates an object as it passes through an X-ray field. This compound motion makes it unnecessary to perform sequential passes or to relocate X-ray equipment between passes to complete a scan. A conveyor may carry a series of closely spaced turntables to give greatly increased throughput; and coordinated translation and rotation, whereby all objects give comparable images, permitting the images to be compared to find defective products. Preferred geometries greatly simplify the image reconstruction mathematics, particularly where the X-ray source is at the center of a circular object path.
