Area of Science:

  • Medical Imaging
  • Magnetic Resonance Imaging (MRI)
  • Biomedical Engineering

Background:

  • Receiver coil design is critical for optimal clinical MR imaging quality.
  • Traditional receiver coils offer either high spatial uniformity (volume coils) or high signal-to-noise ratio (SNR) (surface coils), but not both.
  • Achieving both high SNR and spatial uniformity simultaneously has been a long-standing challenge in MRI.

Purpose of the Study:

  • To develop and evaluate a hybrid receiver coil system for simultaneous MR signal acquisition.
  • To achieve both high spatial uniformity and high SNR in clinical MR imaging.
  • To overcome the limitations of conventional receiver coil designs.

Main Methods:

  • Simultaneous acquisition of MR signals using a combination of body and surface coil arrays.
