Abstract: The disclosure relates generally to a method of three dimensional (3D) tomographic volume reconstruction for computed tomography (CT) using vector processors and more specifically to an optimized implementation which pre-computes back projection weights and perspective geometry data associated with a given CT device as down-sampled tables. The down-sampled perspective geometry data and the weight table are interpolated dynamically as part of the volume reconstruction process for an object scanned using the given CT device.
