A new spherical dose model speeds up stereotactic radiosurgery calculations. This faster method aids iterative treatment optimization, requiring only one empirical value and offering gradient information for improved efficiency.

Area of Science:

  • Medical Physics
  • Radiotherapy Physics

Background:

  • Conventional 3D dose calculations in stereotactic radiosurgery (SRS) are computationally intensive.
  • Iterative optimization for multiple isocenter treatments requires numerous repetitive dose calculations, leading to significant time delays.

Purpose of the Study:

  • To develop a computationally efficient spherical dose model for SRS.
  • To facilitate faster iterative optimization of complex SRS treatment plans.

Main Methods:

  • A spherical dose model was derived using a parametrized convolution of collimator width and a dose spread kernel.
  • The model assumes spherically symmetric dose distributions for computational speed.

Main Results:

  • The proposed spherical dose model significantly accelerates dose calculations compared to conventional methods.

  • The model is easily implemented and requires only a single empirically derived value.
  • The model is differentiable, providing gradient information beneficial for optimization algorithms.

    • Conclusions:

    • The spherical dose model offers a fast and practical solution for SRS dose calculation and optimization.
    • This approach enhances the efficiency of iterative treatment planning, particularly for complex, multi-isocenter SRS cases.
