However, strategies that lead to enhancement of inflow effects come at the expense of prolonged scan times. This study proposes a combination of two dimensional (2D) acceleration in the phase-encode dimensions via compressed sensing (CS) and one dimensional (1D) partial Fourier (PF) data acquisition in the readout dimension to reduce echo time. An improved projections-onto-convex-sets (POCS) reconstruction framework is utilized, which decomposes the problem into 1D PF projections along the readout dimension, and 2D CS projections along the phase-encode dimensions. This framework enables scan-efficient TOF MR angiography imaging to help maintain high vessel-background contrast.TurkishCompressed sensingTOFPartial Fourier reconstructionJoint partial fourier and compressed sensing reconstruction for accelerated time-of-flight MR angiographyHızlandırılmış uçuş-zamanlı MR anjiyografi için bütünlȩsik kısmi fourier ve sıkıştırılmış algılama geriçatımıConference Paper10.1109/SIU.2018.8404404
