Multiple receiver coils in MRI can reduce scan times. This review explores using their complementary data to minimize artifacts from patient motion and blood flow, improving image quality.

Area of Science:

  • Medical Imaging
  • Magnetic Resonance Imaging (MRI)

Background:

  • Multiple receiver coils in MRI provide complementary views, enabling faster scan times.
  • Image artifacts from patient motion and physiological processes (e.g., blood flow) can compromise image quality.

Purpose of the Study:

  • To review methods for reducing MRI image artifacts using data from multiple receiver coils.
  • To explore how complementary coil information can correct motion- and flow-induced artifacts.

Main Methods:

  • Review of techniques utilizing multi-coil MRI data for artifact reduction.
  • Methods include data discarding in affected regions and motion estimation for data correction.

Main Results:

  • Demonstration of artifact reduction in MRI images corrupted by motion.
