A table for the rapid determination of RET and TDF values

Area of Science:

• Radiation Oncology
• Medical Physics
• Radiotherapy Planning

Background:

• Accurate calculation of radiation dose and fractionation is crucial for effective cancer treatment.
• Existing methods for determining Radiation Effect on Normal Tissue (RET) and Time, Dose, Fractionation (TDF) values can be time-consuming.
• Realistic treatment planning requires efficient tools for evaluating various fractionation schemes.

Purpose of the Study:

• To develop a rapid method for determining RET and TDF values for standard five-day-a-week radiotherapy schedules.
• To facilitate easy comparison of different fractionation schemes and identify equivalent treatments.
• To enable quick calculation of TDF for interrupted or split-course treatment regimens.

Main Methods:

• Development of a novel table for calculating RET and TDF values.
• Utilizing established decay tables (Orton and Ellis) for calculations.
• The table is designed for five-day-a-week therapy schemes.

Main Results:

• The devised table allows for rapid determination of RET and TDF values.
• It simplifies the comparison of different fractionation schemes.
• The table facilitates the calculation of TDF for interrupted treatment courses.

Conclusions:

• The developed table provides an efficient tool for radiotherapy treatment planning.
• It aids in comparing and devising equivalent fractionation schemes.
• The method is applicable to interrupted and split-course treatments, enhancing planning flexibility.
