3D Tomography Reconstruction

Eigenor Corporation has developed a high-end 3D reconstruction software module that uses the Feldkamp reconstruction algorithm. The main benefits of Eigenor’s solution are a very high quality of result and fast CPU based reconstruction as well as advanced capabilities to remove unwanted artifacts that could be generated by impenetrably dense elements in the reconstructed object. The software also supports arbitrary and unorthodox geometries and less than
360 degrees of sweeps around the object.

Eigenor has also a very fast statistical inversion engine that
can be used in 3D reconstruction. Statistical inversion methods typically give better reconstruction results with smaller amount of projections. The downside of these methods is the generally unacceptably large calculation time. Eigenor’s statistical inversion engine can make many of these slow calculations feasible to do, even in real time. In an experiment few years back the same statistical inversion problem for 3D reconstruction was solved at the Finnish supercomputing center with their Cray supercomputer. Comparing it with Eigenor implementation with then current state-of-the-art Mac computer, both calculations gave the same result. However, the Cray with a commonly used implementation needed 3.5 months to solve the problem, our solution did the same in less than half an hour.
