This study introduces a simple, accurate semi-empirical formula for dose computation in irregular radiation therapy fields. This method allows for manual calculation, aiding treatment planning for complex tumors.

Area of Science:

  • Medical Physics
  • Radiation Oncology
  • Radiotherapy Dosimetry

Background:

  • Accurate dose computation is crucial for treating malignant tumors with large irregular radiation fields.
  • Existing computational methods are often complex, computer-dependent, and time-consuming.
  • Equivalent field methods are insufficient for irregular field geometries.

Purpose of the Study:

  • To develop a simple and accurate semi-empirical formula for dose computation in irregular radiation fields.
  • To estimate radiation dose outside the primary field and in shielded regions.
  • To provide a computationally feasible alternative for radiotherapy planning.

Main Methods:

  • A novel semi-empirical formula was developed for dose calculation in irregular fields.
