A novel imaging method enhances material density profiling for challenging samples. This robust technique utilizes a specialized gradient coil for improved imaging of low gyro-magnetic ratio nuclei.

Area of Science:

  • Materials Science
  • Nuclear Magnetic Resonance (NMR) Imaging

Background:

  • Imaging materials with short transverse relaxation times is challenging.
  • Previous centric scan phase encode methods had limitations in robustness.

Purpose of the Study:

  • To present a new, robust centric scan imaging methodology for density profiling.
  • To enable density imaging of low gyro-magnetic ratio non-proton nuclei.
  • To introduce a novel gradient coil design for enhanced imaging capabilities.

Main Methods:

  • Development of a new centric scan imaging sequence.
  • Design and construction of a novel multi-layer, water-cooled, 1D magnetic field gradient coil (7.62 cm diameter, 6 mT/m/A efficiency).
  • Application of the method to density-weighted proton (1H) and lithium ion (7Li) imaging.
