Previously, we implemented a GPU-based image reconstruction technique called the Illinois Massively Parallel Acquisition Toolkit for Image reconstruction with ENhanced Throughput in MRI (IMPATIENT MRI)  ...  Through implementation of optimized gridding into our iterative reconstruction scheme, speed-ups of more than a factor of 200 are provided in the improved GPU implementation compared to the previous accelerated  ...  This paper focuses on accelerating the calculation of F H y c and F H F so as to accelerate the entire 3D non-Cartesian high-resolution MRI reconstruction approach to clinically-feasible times.  ...

Streaming Architectures for Medical Image Reconstruction [article]

Brendan West, University, My
To make matters worse, the high raw data bandwidth found in 3D ultrasound requires on-chip volume reconstruction with a tight power dissipation budget---dissipation of more than 5~W may burn the skin of  ...  Unfortunately, emerging computational imaging techniques, such as those found in 3D ultrasound and iterative magnetic resonance imaging (MRI), are severely limited by the high computational requirements  ...  More recently, a Toeplitz-based MRI reconstruction strategy was implemented on GPUs in [12] .  ...
