Publikováno v: Magnetic Resonance in Medicine. 55:16-22
Sensitivity encoding (SENSE) and partial Fourier (PF) techniques both reduce MRI acquisition time. Two-dimensional SENSE uses coil sensitivities to unfold aliasing in the phase/ slice-encoding plane. One-dimensional PF and homodyne reconstruction are
