Innovation Summary:
This invention presents a hybrid X-ray tube system that uses electron beam manipulation to replace the need for traditional source gratings. Instead of relying on mechanical source grating structures, the system modulates the X-ray output via controlled steering of the electron beam. The dynamic beam pattern generates structured illumination at the phase grating, producing moiré patterns for phase-contrast and dark-field imaging. The solution integrates seamlessly with electric fringe scanning detectors, enabling full grating-based imaging with no moving parts. This design simplifies X-ray source construction while increasing imaging throughput and stability. It enables adaptive X-ray beam shaping for personalized imaging protocols and reduced radiation exposure.

Challenges / Opportunities:
Conventional source gratings add complexity, alignment constraints, and mechanical failure points in advanced X-ray systems. They limit the ability to rapidly adapt imaging parameters in real-time. By introducing dynamic beam control, this invention enhances precision and scalability. It enables next-generation flat-panel-based CT and phase-contrast systems for healthcare and materials diagnostics.

Key Benefits / Advantages:
✔ Eliminates physical source gratings
✔ Enables programmable X-ray illumination
✔ Supports phase and dark-field imaging modes

Applications:
• Adaptive diagnostic X-ray systems
• High-resolution non-invasive testing
• Phase-contrast CT development
