A novel method replaces conducting planes with resonant element arrays in resonators. This magnetic resonance imaging coil design offers uniform sensitivity across the field of view.

Area of Science:

  • Electromagnetics
  • Magnetic Resonance Imaging (MRI)

Background:

  • Traditional split resonators often use conducting planes.
  • Achieving uniform sensitivity in MRI receive coils is crucial for image quality.

Purpose of the Study:

  • To introduce a novel method of images application for resonator design.
  • To investigate the use of a plane array of resonant elements as a substitute for conducting planes.
  • To evaluate the sensitivity uniformity of a split resonator-plane array system in MRI.

Main Methods:

  • Application of the method of images to resonator design.
  • Development of a semicylindrical or split resonator with a plane array of resonant elements.
  • Experimental testing of a low-pass split resonator-plane array system as a magnetic resonance imaging receive coil at 0.5 Tesla.

Main Results:

  • Demonstrated that a plane array of resonant elements can effectively replace a conducting plane.
  • The experimental split resonator-plane array system achieved uniform sensitivity (approximately +/- 3%) across the field of view.
  • The system functioned effectively as a magnetic resonance imaging receive coil.

Conclusions:

  • The novel application of the method of images provides an effective design strategy for resonators.
  • Plane arrays of resonant elements are a viable alternative to conducting planes in split resonators.
  • The developed magnetic resonance imaging receive coil exhibits excellent sensitivity uniformity, promising improved image quality.
