Area of Science:

  • Magnetic Resonance Imaging (MRI)
  • Medical Physics
  • Image Reconstruction

Background:

  • Wave encoding is an advanced MRI technique that enables faster data acquisition.
  • Accurate estimation of wave point spread function (PSF) and coil sensitivities is crucial for high-quality wave-encoded imaging.
  • Subsampling k-space in wave encoding can lead to artifacts if not properly handled.

Purpose of the Study:

  • To develop and evaluate a self-calibrating method for estimating wave PSF and coil sensitivities from subsampled wave-encoded k-space.
  • To assess the performance of this method in wave-encoded 3D Turbo Spin Echo (TSE) imaging.

Main Methods:

  • A low-rank subspace parametric model was used for k-space trajectory representation.
  • A two-stage autofocus metric calibrated the wave PSF.
  • Coil sensitivities were extracted from corrected k-space data.
  • Wave encoding gradients were integrated into a 3D TSE sequence.
  • Phantom and in vivo brain experiments were conducted.

Main Results:

  • Self-calibrated wave PSF robustly corrected wave encoding artifacts with sufficient autocalibration data.
  • Wave-encoded parallel imaging (PI) reconstruction showed improved performance compared to Cartesian-encoded PI.
  • Reduced aliasing artifacts and noise amplification were observed in wave-encoded PI.

Conclusions:

  • The proposed self-calibrating method enables robust calibration of wave PSF and coil sensitivities from subsampled k-space.
  • This approach significantly enhances overall image quality for accelerated 3D TSE imaging.
