文摘
- •
Ultrafast UTE imaging is demonstrated on granular material with T2∗ = 185 μs.
- •
Compressed sensing and Hermitian symmetry are used to reduce acquisition time.
- •
Images are acquired in 25 ms with a spatial resolution of 1 mm × 1 mm × 2 mm.
- •
Volume of voxels is ∼15 times smaller than previous images acquired in the same time.
