X-ray Imaging

10.8K
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Area of Science:

  • Medical Physics
  • Radiation Dosimetry
  • Radiological Imaging

Background:

  • Staff exposure during fluoroscopic interventional procedures necessitates accurate dosimetric control.
  • Traditional methods for radiation transport simulation can be computationally intensive.

Purpose of the Study:

  • To present and evaluate a novel ray casting approximation for radiation transport.
  • To compare its accuracy and efficiency against full Monte Carlo simulations and experimental dose measurements.

Main Methods:

  • Modeled C-arm X-ray source and used Geant4 Monte Carlo for initial radiation transport and scatter calculation.
  • Developed a ray casting approximation to trace photons interacting with a staff phantom.
  • Validated the approximation using Thermoluminescent Dosimeters (TLDs) and Geant4 simulations across various C-arm angulations.

Main Results:

  • The Geant4-Monte Carlo simulation showed agreement within 3% with experimental measurements.
  • Ray casting approximation demonstrated percentage differences of -7% to -29% in high-dose regions near the X-ray source.
  • Significant deviations (-75% to -83.8%) were observed in low-dose regions away from the source.

Conclusions:

  • The proposed ray casting approach provides rapid scatter dose estimation with calculation times under one second.
  • It offers high precision in high-dose regions relevant for staff protection.
  • The method allows for efficient visualization of scatter dose propagation on a phantom surface.
