X-ray Imaging System Depth Camera Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional X-ray imaging systems require manual configuration by operators, which is time-consuming and prone to errors due to the lack of clear visibility of adjustments, leading to inefficient use and potential multiple X-ray captures, especially with existing automated systems that rely on 2D image processing or depth cameras which are processor-intensive and lack operator verification.
Innovation Solution
A method using depth cameras to obtain and display impression images on a client device, allowing operators to interactively correct the geometric configuration of the X-ray imaging system by visualizing the area covered by the X-ray bundle, enabling translation, rotation, and resizing corrections, which are then converted and applied to the system, facilitating efficient and accurate configuration without the need for manual presence at the X-ray system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual configuration is used by the operator, then the system can be configured with simple equipment, but the configuration process becomes time-consuming and error-prone
Solution Approach 1:
The system performs self-configuration by automatically determining geometric parameters using depth camera data and coordinate transformations, eliminating the need for manual operator input while maintaining high accuracy through automated verification
Solution Approach 2:
The system provides real-time visual feedback to the operator displaying the current geometric configuration and allowing verification of automatically determined parameters, enabling correction if needed while maintaining automated efficiency
2Productivity
If automated configuration using 2D image processing is used, then configuration speed is improved, but processing power requirements increase and accuracy decreases
Solution Approach 1:
The system transitions from 2D image processing to 3D depth camera data, enabling accurate geometric parameter extraction in three-dimensional space while maintaining computational efficiency through direct depth measurement rather than complex 2D reconstruction
3Reliability
If the operator is required to verify configuration adjustments, then configuration accuracy is improved, but the operator must be physically present at the system which reduces efficiency
Solution Approach 1:
The system uses a display interface as an intermediary, projecting the geometric configuration and depth camera data to a remote client device, allowing the operator to verify and control configuration parameters without being physically present at the X-ray system

AI summary
An X-ray system for taking an X-ray image of an object includes an X-ray source, an X-ray detector, depth camera(s) covering at least an area covered by an X-ray bundle and configured to obtain depth images and a client device including a display adapted to display an impression image to a user. The system further includes a controller configured to derive the impression image including a representation of this area from the depth images; and to obtain from the client device a first geometric position correction of the X-ray imaging system with respect to this impression image; and to convert the first geometric position correction to an actual geometric position configuration of the X-ray imaging system by a known relation between the one or more depth cameras and the X-ray imaging system.
