Area of Science:

  • Medical Imaging
  • Biomedical Engineering
  • Neuroscience

Context:

  • Positron Emission Tomography (PET) studies require precise patient head immobilization.
  • Current methods may lack accuracy in head fixation and repositioning between scans.
  • Variability in patient anatomy poses challenges for consistent head positioning.

Purpose:

  • To develop and evaluate a novel headholder system for PET studies.
  • To enhance the accuracy of patient head fixation and repositioning.
  • To improve the reliability of immobilization for repeated PET scans.

Summary:

  • A new headholder system was developed using an acrylic frame and a thermoplastic resin headrest with adaptive gel.
  • Individualized thermoplastic face masks were created for each patient, securing to the holder via a plastic taper.

  • The system allows for head fixation within 2-3 minutes, demonstrating good immobilization and accurate repositioning between PET studies.

    • Impact:

    • Improved data quality and consistency in PET imaging through enhanced head immobilization.
    • Potential for reduced scan times and increased patient comfort.
    • Facilitates more reliable longitudinal studies and precise image registration in neuroimaging and other PET applications.
