Respiratory motion up to 3 cm can impact radiation therapy. This study introduces a displacement-binned computed tomography (CT) imaging method to improve accuracy by accounting for breathing-induced anatomical motion during treatment planning.

Area of Science:

  • Medical Imaging
  • Radiation Oncology
  • Radiotherapy Physics

Background:

  • Respiratory motion significantly affects thoracic and abdominal tumor radiation therapy planning and delivery.
  • Existing methods to compensate for respiratory motion have limitations.
  • Advancements in computed tomography (CT) allow tracking of respiratory-induced anatomical motion.

Purpose of the Study:

  • To propose and evaluate a novel method for generating CT images that account for respiratory-induced anatomical motion using displacement-binned image sets.
  • To develop an interim solution for extracting and utilizing displacement-binned CT data from existing scanner outputs.

Main Methods:

  • A method was developed to extract displacement-binned CT image data from prospectively acquired breathing-phase data on a multislice helical CT scanner.

  • Projection data were binned at small phase intervals before reconstruction.
  • Images were correlated to an external fiducial marker's displacement and resorted based on displacement and assigned phase.

    • Main Results:

    • The developed technique demonstrated potential for improving CT image reconstruction by accounting for respiratory motion.
    • The method allows for the transfer of displacement-binned image data sets to treatment-planning systems for analysis.
    • Some improvement in image reconstruction was observed, validating its utility as an interim solution.

    Conclusions:

    • Displacement-binned CT image sets offer a promising approach to mitigate the adverse effects of respiratory motion in radiation therapy.
    • The developed interim method provides a viable solution for utilizing current CT technology to improve motion-compensated treatment planning.
    • Further development is needed to overcome limitations related to CT software phase intervals for optimal implementation.
