This study introduces a real-time MRI imaging technique using continuous radial acquisition. This method minimizes motion distortions and temporal blurring, enabling visualization of dynamic processes like active joint motion.

Area of Science:

  • Medical Imaging
  • Radiology
  • Biomedical Engineering

Background:

  • Recent reductions in MRI acquisition times have opened new application areas.
  • Dynamic processes require high temporal resolution for visualization, enabling interactive or interventional MRI and functional imaging.

Purpose of the Study:

  • To present a novel approach for quasi real-time magnetic resonance imaging (MRI).
  • To enable visualization of dynamic processes with high temporal resolution.

Main Methods:

  • Utilized a continuous radial acquisition scheme for MRI.
  • Employed projection reconstruction (PR) techniques to minimize motion-related image distortions.
  • Implemented modifications to the acquisition scheme and reconstruction techniques to reduce temporal blurring.
