AI Technical Summary
Technical Problem
Existing X-ray imaging systems require a technical interface between the video camera and X-ray system for synchronization, which is cumbersome and not easily retrofittable.
Method used
An imaging system that uses a video camera system separate from the X-ray detector to determine X-ray exposure timing based on pixel saturation, without requiring a communication interface, using CMOS sensors to detect X-ray photons and generate timing information independently.
Benefits of technology
Enables synchronization between video and X-ray images without additional hardware, providing a portable solution that can be applied to various X-ray systems, supporting quality control, foreign body detection, and respiratory/cardiac state monitoring.

Abstract
An imaging system is used for capturing images of a subject during X-ray examination. It comprises a video camera system, separate to the X-ray image generation, for generating video camera images. The video camera images are processed to determine that a captured video camera image is synchronized with an X-ray exposure, based on saturation of one or more pixels of the captured video camera image. Timing information can then be generated associating the timing of the video camera images with the timing of the X-ray exposure.
