A new reusable silicone foil dosimeter using optically stimulated luminescence (OSL) of magnesium borate (MBO) material accurately maps proton Bragg curves. This technology shows potential for precise proton therapy dosimetry, comparable to current standards.

Area of Science:

Medical Physics
Radiation Dosimetry
Materials Science

Background:

Proton therapy requires precise dose distribution measurements.
Bragg curve characterization is crucial for treatment planning.
Existing 2D dosimetry methods have limitations.

Purpose of the Study:

To develop and validate a novel reusable silicone foil dosimeter for proton Bragg curve measurements.
To assess the accuracy of this new dosimeter against established methods.
To enable comprehensive characterization of proton beam properties.

Main Methods:

Utilized a PMMA therapeutic wedge and a reusable MgB4O7:Ce,Li (MBO) silicone foil dosimeter.
Employed a 3D-printed optical detection setup with blue LED illumination and an EMCCD camera for 2D OSL mapping.

Performed measurements on clinically relevant proton beams (58.8 and 61.1 MeV).

Validated results against Monte Carlo simulations and Gafchromic EBT3 films.

Main Results:

Achieved direct, single-shot 2D mapping of complete proton Bragg curves.
Demonstrated sub-millimetre accuracy in localizing critical proton parameters (peak-to-plateau, FWHM, distal fall-off).
Showed performance comparable to Gafchromic EBT3 films for key dosimetric parameters.

Conclusions:

MBO-based silicone foil technology offers a promising approach for 2D proton dosimetry.
The prototype enables accurate measurement of clinically relevant Bragg curve parameters.
Further corrections are needed to address systematic differences related to optical diffusion and quenching.
