Description
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.
