Accelerating Magnetic Resonance Three-Dimensional Imaging with Compressed Sensing and Multi-GPU Computing

Abstract (in Japanese) (See Japanese page) 
(in English) Compressed sensing (CS) has inspired significant interest because of its potential to reduce data acquisition time. However, CS reconstruction is an iterative reconstruction technique, especially in 3D image reconstruction so it is more computationally intensive than traditional inverse Fourier reconstruction. In this study, we examine to accelerate the 3D CS reconstruction by using the Graphics Processing Unit (GPU) as a general-purpose use. Experimental results show that CS reconstruction with 256×256×32 images based on Multi-GPU was executed in 11s while CPU computing cost was 478s.
