Model-based iterative reconstruction (MBIR) for X-Ray CT is computationally expensive, yet highly parallelizable, making it amenable to multi-GPU implementation. However …
Despite dramatic improvements in GPU and interconnect architectures, inter-GPU communication remains the most significant architectural bottleneck in multi-GPU systems …
A concise and highly performant branchless formulation of a Joseph-type interpolating ray- casting algorithm for the computation of X-ray projections is presented. It efficiently utilizes …

One of the latest trends in Computed Tomography (CT) is the reduction of the radiation dose delivered to patients through the decrease of the amount of acquired data. This reduction …
We introduce statistical iterative reconstruction (SIR) for high-resolution computed tomography (CT) in real-time and the surrounding framework. Our findings help to multiply …
Advancements in medical imaging research are continuously providing doctors with better diagnostic information, removing the need for unnecessary surgeries and increasing …
