Classic algebraic reconstruction technology (ART) for computed tomography requires pre-determined weights of the voxels for the projected pixel values to build the equations. However, such weights cannot be accurately obtained due to the high physical complexity and computation resources required. In this study, we propose a semi-case-wise learning-based method named Weight Encode Reconstruction Network (WERNet) to co-learn the target voxel values and intrinsic physics of the case in a self…

Deep Learning Computed Tomography: Learning Projection-Domain Weights From Image Domain in Limited Angle Problems
A new type of cone-beam back-projection layer is proposed, efficiently calculating the forward pass of this layer, and it is shown that the learned algorithm can be interpreted using known concepts from cone beam reconstruction: the network is able to automatically learn strategies such as compensation weights and apodization windows.

Point spread function based image reconstruction in optical projection tomography.
A novel optical tomographic image reconstruction technique is presented that incorporates the point spread function of the imaging lens in an iterative reconstruction that shows greatly reduced radial and tangential blurring over the entire mm2 field of view, and a significantly improved signal to noise ratio.
