Area of Science:

  • Medical Physics
  • Radiotherapy Technology

Background:

  • Conventional radiotherapy simulators typically use 2D fluoroscopy.
  • There is a need for advanced imaging techniques in radiotherapy for precise treatment delivery.

Purpose of the Study:

  • To report on a custom 3D computed tomography (CT) extension for radiotherapy simulators.
  • To enable the production of fully 3D tomographic studies from cone-beam fluoroscopy output.

Main Methods:

  • Developed a custom 3D CT extension using a PC system and proprietary software.
  • Acquired and reconstructed cone-beam data from commercial simulator fluoroscopy video chains.
  • Focused on multi-slice, single-scan reconstruction capabilities.

Main Results:

  • The custom extension successfully produced fully 3D tomographic studies.
  • Achieved multi-slice, single-scan reconstruction, surpassing single-slice commercial solutions.
  • Demonstrated potential for improved image quality and data acquisition efficiency.

    • Conclusions:

    • The custom 3D CT extension is a viable and potentially superior alternative to commercial CT options for radiotherapy simulators.
    • This technology facilitates advanced radiotherapy applications, including on-line treatment planning, patient treatment verification, and registration.
