The technology is a novel type of particle detector based on scintillation, with precise spatial resolution and radiation hardness.
The particle detector device consists of a single microfluidic channel filled with a liquid scintillator, which is designed to define an array of optically separated scintillating waveguides, each independently coupled to a photo-detector. The device is housed within the patient treatment apparatus, positioned to intercept the beam line. During online treatment, the particle beam passes through the device and particles interact with the scintillant in the micro-channels to produce a luminous event/flash of light, which is captured by photo-detectors and recorded.
