Sparsity transform k-t principal component analysis for accelerating cine three-dimensional flow measurements
Magnetic Resonance in Medicine, 08/21/2012
Knobloch V et al. – Based on these findings, spatial resolution of three–dimensional flow measurements was increased to 0.8 mm isotropic resolution with prospective 8–fold undersampling and sparsity transform k–t principal component analysis reconstruction. Volumetric data were acquired in 6 min. Pathline visualization revealed details of helical flow patterns partially hidden at lower spatial resolution.
