This study presents a novel method for creating 3D compensating filters for radiation therapy. This technique precisely calculates tissue deficits to improve photon beam accuracy and treatment efficacy.

Area of Science:

Medical Physics
Radiation Oncology
Radiotherapy Physics

Background:

Accurate radiation dose delivery is critical in cancer treatment.
Compensating filters are used to equalize radiation absorption in varying tissue depths.
Traditional methods for filter design can be complex and time-consuming.

Purpose of the Study:

To describe a computer-aided method for designing 3-dimensional compensating filters for photon beam radiation therapy.
To enhance the precision of radiation dose distribution by accounting for tissue deficits.

Main Methods:

A radiopaque grid is applied to the patient's surface.
Stereo shift radiographs are acquired to capture the treatment area.
Computer analysis calculates tissue deficit information.
