Here we present accelerated images by PhasE-Constrained Over Sampled (PECOS) MRI in our home-made Halbach MRI scanner (70 mT). We show projection images of a phantom obtained in our “PhysioMRI” scanner (Fig. 1(a)), a home-made scanner designed for musculoskeletal imaging at low field strengths. We use cartesian turbo spin echo (TSE) sequence to sample the k-space. Image reconstructions are performed by phase conjugate reconstruction and by PECOS.
