This study developed a new head and neck MRI coil, enhancing image sensitivity and coverage. The improved coil technology offers better diagnostic capabilities for head and neck imaging.

Area of Science:

  • Medical Imaging
  • Radiology
  • Biomedical Engineering

Background:

  • Magnetic Resonance Imaging (MRI) is crucial for head and neck diagnostics.
  • Existing MRI coils may have limitations in sensitivity and coverage for this complex anatomical region.

Purpose of the Study:

  • To develop and evaluate a novel phased array coil for improved MRI of the head and neck.
  • To enhance image sensitivity and anatomical coverage compared to conventional coils.
  • To implement and assess an algorithm for correcting reception profile nonuniformity.

Main Methods:

  • Construction of a head and neck phased array coil.
  • Comparative analysis of sensitivity and coverage using phantom studies against volume and temporomandibular joint surface coils.
  • Development and application of a reception profile nonuniformity correction algorithm.
