Method for measuring radiotherapy doses

Non-invasive system for measuring the radiation dose absorbed during radiotherapy treatments.

How does it work?

The idea behind the invention is that when a subject is exposed to a beam of ionizing radiation, whether charged particles, neutrons, or high-energy photons, they experience a charge imbalance proportional to the absorbed dose. The proposed system non-invasively measures this charge imbalance, providing a direct indication of the absorbed radiation, unlike traditional methods which determine the dose indirectly by measuring the amount of radiation emitted from the source.

Applications

• In-vivo dosimetry for radiotherapy
• Radioprotection
• Environmental radiation monitoring
• Online measurement in hadron therapy

Advantages

• Non-invasive measurement on patients
• Direct dose measurement
