Radiation Detection Apparatus with Scintillator and Data Compression

The patent replaces expensive and unstable semiconductor materials (CdTe, CZT) with a more stable alternative configuration using scintillator materials in combination with photodetectors. This substitution eliminates the stability issues associated with semiconductor materials while maintaining detection capabilities through the scintillation process, effectively using a more reliable material system.

The patent introduces scintillator materials as an intermediary between the X-ray photons and the photodetectors. The scintillators convert high-dose X-rays into visible light photons, which are then detected by the photodetectors. This intermediary conversion process reduces noise accumulation while maintaining photon counting accuracy, as the scintillation process effectively mediates the interaction between high-dose radiation and the detection system.

The patent divides the detection process into distinct functional segments: scintillation conversion, photoelectric conversion, signal amplification, and digital processing. This segmentation allows each component to be optimized independently, enabling fast image acquisition through efficient signal processing while maintaining image quality through dedicated detection circuits for each pixel element.

The patent merges multiple functions into integrated pixel elements that combine scintillator materials, photodetectors, and signal processing circuits in a unified structure. This merging approach enables parallel detection across multiple pixels while reducing overall device complexity by eliminating the need for separate components and interconnections for each function within each pixel element.
