RF-spoiled radial FLASH sequence without cardiac gating and during free breathing Sequence parameters: TR 2.0ms TE 1.3 ms Flip angle 8° Matrix Size 128x128 (two-fold oversampling, resulting in 256 sample points for each radial spoke) Radial Spokes: 125 In Plane Resolution 2mmx2mm Slice Thickness 8mm 3T System 32 channel body array coil, compressed to 12 virtual channels using svd based coil compression ote: This data set was acquired with a radial acquisition. The corresponding k-Space trajectory is also included (256x125 matrix k). The Non-Uniform-FFT Toolbox is needed for reconstruction of this data set.
