Area of Science:

  • Medical Physics
  • Radiation Oncology

Background:

  • Electron beam therapy verification is difficult due to the limited range of electrons in tissue.
  • Accurate patient positioning is crucial for effective radiation delivery and minimizing off-target exposure.

Purpose of the Study:

  • To evaluate the utility of a linac's film mode for verifying electron beam fields.
  • To assess the accuracy of using film mode images for electron field positioning and error detection.

Main Methods:

  • Utilized the film mode of modern linear accelerators (linacs) to irradiate electron fields with a low photon dose.
  • Acquired portal images during film mode irradiation.
  • Compared acquired images with simulator images or digitally reconstructed radiographs (DRRs).

Main Results:

  • The film mode allows for the irradiation of electron fields with a minimal photon dose.
  • Images obtained from film mode are suitable for comparison with simulator images or DRRs.
  • This method enables the determination of electron field position and the detection of positioning errors.

Conclusions:

  • Linac film mode offers a practical solution for verifying electron fields in radiation therapy.
  • This technique enhances the accuracy of patient positioning for electron beam treatments.
  • It aids in quality assurance by detecting and correcting setup errors before treatment delivery.
