Topic: Dual Domain Neural Networks for Sparse X-ray Computed Tomography.

Speaker:  Theodor Cheslerean-Boghiu, Lasser Group

Date and Time: Tuesday, 4 May 2021, 1:00 pm

Abstract: Sparse sampling in X-ray Computed Tomography (CT) is an interesting option towards reducing dose. Recently, the success of deep learning techniques in a lot of medical imaging applications has prompted an increased interest in data-driven tomographic reconstruction algorithms. Nevertheless, most of the proposed solutions boil down to denoising steps performed either pre-reconstruction on the sinogram or post-reconstruction on the reconstructed image, with no reconstruction being performed as part of the network model.
In this presentation, I will talk about an improved deep neural network architecture (DNN) which combines a fine-tuned Filtered Backprojection (FBP) operation with a dual domain filtering step applied on both the sinogram and reconstructed image to produce artifact-free reconstructions from sparse data and we present its performance potential in experiments with clinical data.
