Proton therapy beam dosimetry with silicon CMOS image sensors

• A 16 mm(2) CMOS Image Sensor with more than 100 000 pixels and with a standard video output was irradiated with 48, 95 and 180 MeV protons. Proton-induced nuclear reactions in silicon were detected as bright spots or tracks in the images. The angular and energy-dependent response of the detector were studied. The application to proton dosimetry is discussed.
