Handheld X-ray Positioning Visualization via Camera and Distance Data

The patent creates a virtual copy of the X-ray projection area by calculating and displaying the projected area on the worktable surface through the camera system. This virtual representation allows operators to see the X-ray area location and size from a distance, eliminating the need to physically approach the beam limiter while maintaining accurate positioning information.

The patent introduces a camera system and processing unit as an intermediary between the beam limiter and the operator. The camera captures images of the worktable, and the processing unit calculates and displays the projected X-ray area, serving as a mediator that translates the physical beam limiter position into visible information for the operator without requiring direct observation of the beam limiter itself.

The patent performs preliminary calculation of the projected X-ray area on the worktable surface before the actual X-ray exposure. By pre-calculating and displaying the projected area based on the beam limiter position and geometry, the system provides operators with advance information about the X-ray area size and location, eliminating the need for time-consuming physical approach and measurement.

The patent implements a feedback mechanism where the camera system continuously monitors the worktable area, and the processing unit calculates and displays the projected X-ray area in real time. This feedback loop provides operators with immediate information about the X-ray area size and position without requiring them to physically approach the beam limiter, thus preventing information loss and reducing time loss simultaneously.
