Solution Overview
Problem
Existing X-ray installations and systems are limited in imaging options, often complex to install and operate, and do not support dual-energy imaging, with combined systems being costly and non-mobile.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two X-ray installations are combined to form an integrated system, then imaging versatility is improved, but device complexity and operational complexity increase
Solution Approach 1:
The system is divided into two independent but compatible X-ray installations, each capable of standalone operation. Each installation has its own control device and operational independence, allowing the system to function as one complex unit or two simpler units depending on needs
Solution Approach 2:
Each X-ray installation is designed with universal capabilities to perform multiple imaging functions independently. The installations can operate in various configurations (vertical/horizontal beam paths, different angular positions) and can be used separately or together, providing multi-functionality without requiring specialized components
2Adaptability or versatility
If two X-ray installations are combined to form an integrated system, then imaging versatility is improved, but ease of operation deteriorates
Solution Approach 1:
Each control device is capable of independently controlling its associated X-ray installation without requiring constant intervention from the other control device. The installations can autonomously perform imaging functions, and the master-slave relationship allows automatic coordination when operating together, reducing operational complexity
Solution Approach 2:
The system allows dynamic switching between operational modes: the two installations can operate independently as separate units or be combined as an integrated system. The master-slave control relationship can be established or dissolved as needed, providing operational flexibility and ease of use
3Adaptability or versatility
If the C-arm forms a full closed circle, then imaging coverage is improved, but ease of operation deteriorates due to limited access space
Solution Approach 1:
The full circular imaging coverage is achieved by segmenting the C-arm into two separate installations, each covering approximately half a circle. This segmentation allows each installation to have an open structure that provides access space, while the combination of both installations achieves complete 360-degree coverage
Solution Approach 2:
Instead of creating a single closed circular C-arm that would block access, the system uses two separate installations positioned at different angular positions. This spatial arrangement in multiple dimensions achieves full circular coverage while maintaining open access space around the examination table
4Manufacturing precision
If fixed 90-degree offset geometry is used in combined systems, then manufacturing precision is improved, but adaptability deteriorates
Solution Approach 1:
The C-arms are designed with adjustable angular positions rather than fixed geometries. Each installation can be independently positioned at different angles, and the master-slave control system coordinates these positions dynamically. This allows the system to achieve precise geometric relationships when needed while maintaining flexibility to change configurations for different imaging requirements

AI summary
An X-ray installation has a base unit on which a C-arm is arranged. An X-ray source and an X-ray detector are arranged on the C-arm. The C-arm forms half of a closed, convex, point-symmetrical curve. The X-ray source and/or the X-ray detector is/are displaceable along the C-arm. In this way, an angle formed by the X-ray source and the X-ray detector with an isocenter of the full circle is adjustable to a minimum value that is less than 180°. Two such X-ray installations can form an X-ray system in which the two X-ray installations are arranged and adjusted such that the closed, convex, point-symmetrical curves of the two X-ray installations form an integrated, closed, point-symmetrical, convex curve and the C-arms of the two X-ray installations form complementary halves of the integrated, closed, convex, point-symmetrical curve.
