X-ray interaction with matter is an energy-dependent process that is contingent on the atomic structure of the constituent material elements.

From stereo vision, it is well known that, for a known imaging geometry, once the same point is identified in two images taken from different directions, then the point's location in 3D space is exactly specified.

To do so, we train shallow neural networks to combine two neighbouring acquisitions into an estimated measurement at an intermediate angle.

Compensating scarce measurements by inferring them from computational models is a way to address ill-posed inverse problems.

Tomographic image sizes keep increasing over time and while the GPUs that compute the tomographic reconstruction are also increasing in memory size, they are not doing so fast enough to reconstruct the largest datasets.

- It requires a fixed number of iterations depending only on the logarithm of a form of signal to noise ratio of the signal.
