This study introduces a novel algorithm for precise 3D brain radiosurgery dose calculations. It combines fast Fourier transform for homogeneous tissues and superposition for complex cases, enhancing treatment accuracy.

Area of Science:

  • Medical Physics
  • Radiotherapy
  • Computational Dosimetry

Background:

  • Modern radiosurgery demands accurate 3D dose calculations for brain treatments.
  • Existing methods may face challenges with complex geometries and tissue inhomogeneities.

Purpose of the Study:

  • To introduce and adapt a novel algorithm for calculating 3D dose distributions in brain radiosurgery.
  • To enhance the precision and efficiency of dose calculations for complex treatment scenarios.

Main Methods:

  • Developed a 3D dose calculation model using ray casting for primary photon intensity.
  • Incorporated Monte Carlo precalculated kernels and considered factors like MLC, blocks, wedges, and compensators.
  • Utilized Fast Fourier Transformation (FFT) for homogeneous media and precise superposition for inhomogeneous cases.

Main Results:

  • The algorithm accurately calculates 3D dose distributions, accounting for inhomogeneities and tissue interfaces.
  • FFT provides rapid dose overviews within seconds for homogeneous conditions.
  • Evaluated and verified the algorithm against dose measurements and Monte Carlo simulations for small fields.

Conclusions:

  • The developed algorithm is a valuable tool for precise radiosurgery dose planning, especially for critical brain locations.
  • The hybrid approach (FFT and superposition) offers both speed and accuracy.
  • This method improves treatment planning for complex radiosurgical cases.
