Magnetic Resonance Imaging data used in the work "Rational Approximation of Golden Angles: Accelerated Reconstructions for Radial MRI". The data is provided in a file format used by the BART toolbox (DOI: 10.5281/zenodo.592960). The *_ind.{cfl,hdr} files store the indices of the different spokes of the corresponding datasets: data_res_S{1597,0987,0377,0233,0089,0055,0021} Type: Radial Dataset Object: Single-slice of T1 sphere of the NIST phantom (Model 106) Sequence: FLASH TR|TE [ms]: 3.2|2.04 FA [deg]: 8 T_RF [ms]: 0.4 BWTP: 1.6 FOV [mm]: 200 Spoke Angle: 2\psi_{16,15,13,12,10,9,7}^1 Sampling: RAGA data_bin_raga, data_bin_ga Type: Radial Single-Shot Dataset Object: Single-slice of T1 sphere of the NIST phantom (Model 106) Sequence: IR FLASH TR|TE [ms]: 2.9|1.77 FA [deg]: 8 T_RF [ms]: 0.4 BWTP: 1.6 FOV [mm]: 200 Spoke Angle: 2\psi_{13}^1, 2\psi^1 Sampling: RAGA data_bin_ga Type: Radial Single-Shot Dataset Object: Single-slice of T1 sphere of the NIST phantom (Model 106) Sequence: IR FLASH TR|TE [ms]: 2.9|1.77 FA [deg]: 8 T_RF [ms]: 0.4 BWTP: 1.6 FOV [mm]: 200 Spoke Angle: 2\psi^1 Sampling: GA data_invivo_ga Type: Radial Dataset Object: Single-slice cardiac short-axis Sequence: FLASH TR|TE [ms]: 2.9|1.77 FA [deg]: 8 T_RF [ms]: 0.4 BWTP: 1.6 FOV [mm]: 320 Spoke Angle: \psi^1 Sampling: Golden-Ratio data_invivo_raga Type: Radial Dataset Object: Single-slice cardiac short-axis Sequence: FLASH TR|TE [ms]: 2.9|1.77 FA [deg]: 8 T_RF [ms]: 0.4 BWTP: 1.6 FOV [mm]: 320 Spoke Angle: \psi_{13}^1 Sampling: RAGA
