This study introduces software for processing magnetic resonance imaging (MRI) data in gel dosimetry. The tool converts MRI scans into relaxation images, aiding radiation therapy dose distribution measurements.

Area of Science:

  • Medical Physics
  • Biomedical Imaging

Background:

  • Gel dosimetry enables 3D absorbed dose measurement in radiation therapy.
  • Magnetic Resonance Imaging (MRI) is crucial for visualizing these dose distributions.

Purpose of the Study:

  • To present a software tool for processing MRI data in gel dosimetry research.
  • To facilitate the conversion of MRI images into relaxation time images.

Main Methods:

  • Developed a MATLAB-based software tool with a graphical user interface (GUI).
  • Implemented a pixel-by-pixel non-linear least squares fitting algorithm for image conversion.
  • Included fundamental image manipulation tools (windowing, zooming, ROI analysis).

Main Results:

  • Successfully converted MRI image collections into longitudinal and transverse nuclear magnetic resonance relaxation images.
