AI Technical Summary

Technical Problem

Existing dual-energy X-ray detectors suffer from high costs and signal crosstalk, making it difficult to meet the market demand for high integration and low cost.

Method used

The system employs a stacked structure of two circuit boards, which are connected and shielded by through-hole pin connectors and U-shaped metal filters. It is then fixed with metal pillars and structural adhesive, reducing the number of connectors and shielding scattered X-rays.

Benefits of technology

This resulted in a compact detector architecture, improved integration, reduced product costs, and enhanced image quality.
