System and method for parallel image reconstruction of multiple depth layers of an object under inspection from radiographic images
First Claim
1. A method of reconstructing cross-sectional images of an object from radiographic images of the object, said method comprising:
- receiving pixels of a radiographic image of an object at an image reconstruction processor that is operable to process said received pixels to reconstruct cross-sectional images of said object, wherein said processing by said image reconstruction processor is independent of the order in which said pixels are received;
for at least a first received pixel, said image reconstruction processor determining a plurality of voxels to which said at least a first received pixel contributes; and
said image reconstruction processor applying a contribution of said at least a first pixel to said plurality of voxels in parallel.

Abstract
A system and method are provided which enable parallel image reconstruction of multiple depth layers of an object. More specifically, a system and method are provided in which pixels are captured for an object and such pixels are processed to reconstruct voxels for multiple depth layers of the object in parallel. In one embodiment, a reconstruction processor comprises at least one input port for receiving pixels of a radiographic image of an object, and at least one input port for receiving position data associated with a received pixel. It further comprises processing logic operable to determine, based at least in part on the received position data of a received pixel, a first and second voxel of a first and second layer of the object, respectively, to which the received pixel contributes, and further operable to apply the contribution of the received pixel to the first and second voxels in parallel.
