[Clinically-oriented hints for the technic of integrated dosage modification in a partial irradiation field]

Area of Science:

• Radiation Oncology
• Medical Physics

Context:

• Current radiation therapy often uses a uniform dose across the entire target volume.
• Tailoring radiation doses to specific sub-volumes is challenging but clinically desirable.

Purpose:

• To present a novel method for applying variable radiation doses within an irradiation volume.
• To describe techniques for integrating dose modification with compensators for simultaneous dose harmonization.
• To enable topographic and anatomic assignment of radiation fields based on irradiation features.

Summary:

• A new method allows for radiation doses to be modified in partial zones of the irradiation volume, deviating from the reference dose.
• Compensator-integrated modification achieves simultaneous dose harmonization in the reference plane.
• Three distinct methods are detailed for assigning radiation fields and partial fields based on topographic, anatomic, and irradiation characteristics.

Impact:

• Facilitates more precise and personalized radiation dose delivery in cancer treatment.
• Offers flexibility in radiation therapy planning for complex cases.
• Enhances the ability to optimize radiation dose distribution according to individual patient anatomy and tumor characteristics.
