Arrangements and Methods for Determining Dose Measurement Quantities and for Determining Energy Information of Incident Radiation from Photons or Charged Particles with Counting Detector Units

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention presents a device and method for more accurately determining the dose and energy characteristics of incoming radiation (photons or charged particles) in real time. It uses a sensor with one or more counting detector units, each equipped to detect and count individual radiation events in specified energy intervals. The system includes calibration and advanced thresholding techniques, allowing not just measurement of radiation dose, but also detailed information about the energy spectrum of the incident radiation. The device can use a variety of arrangements including pixelated semiconductor arrays (such as the Medipix2 chip) with optional absorbers of varying materials and thicknesses to refine measurements.
