Dynamic keyhole: A novel method to improve MR images in the presence of respiratory motion for real‐time MRI

Purpose: In this work, the authors present a novel magnetic resonance imaging reconstruction method to improve the quality of MR images in the presence of respiratory motion for real‐time thoracic image‐guided radiotherapy. Methods: This new reconstruction method is called dynamic keyhole and utiliz...
