This study introduces a new optical device for real-time head motion measurement during brain emission computed tomographic (ECT) imaging. The system accurately tracks motion to potentially correct imaging data, improving diagnostic quality.

Area of Science:

  • Medical Imaging
  • Biomedical Engineering
  • Neuroscience

Background:

  • Subject motion during brain imaging, particularly emission computed tomography (ECT), introduces artifacts and reduces image resolution.
  • Accurate measurement of head motion is crucial for correcting ECT data and enhancing image quality.

Purpose of the Study:

  • To develop and validate a novel optical device for real-time, external measurement of head motion during ECT brain imaging.
  • To assess the device's accuracy and reliability in quantifying translational and rotational movements.

Main Methods:

  • An optical system utilizing triangulation of three miniature lights on the patient's head, tracked by two position-sensitive detectors.
  • Real-time data acquisition and processing to determine rotational and translational coordinates every 0.7 seconds.

  • Comparison with a mechanical test fixture for linearity and accuracy, and with an electromagnetic motion detector in human subjects.

    • Main Results:

    • The optical system demonstrated linearity and accuracy with minimal crosstalk when compared to a mechanical test fixture.
    • In a two-subject study, the optical device showed good agreement with a commercial electromagnetic motion detector, with a root mean square difference below 0.6 degrees for angular motions.

    Conclusions:

    • The developed optical device provides accurate and reliable real-time measurement of head motion during ECT brain imaging.
    • This technology holds potential for motion correction in ECT studies, ultimately improving diagnostic image quality and patient outcomes.
