Solution Overview
Problem
Existing X-ray apparatuses with C-arms require centralized and often single-person operation for positioning, which can be cumbersome and require extensive training, especially in dynamic medical environments where complex movements are needed.
Innovation Solution
An X-ray apparatus with sensors that detect deformation caused by operator force on the C-arm, allowing decentralized and intuitive control through a control device that adjusts actuators based on sensor output, enabling multiple personnel to control the C-arm's movement without the need for specialized training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If centralized control modules (joysticks, pushbuttons) are used for C-arm positioning, then positioning precision can be achieved, but operational complexity and training requirements increase
Solution Approach 1:
The C-arm structure itself serves as the control interface. When an operator applies force to any part of the C-arm, the structure deforms and this deformation is directly detected by sensors, automatically triggering the appropriate actuator response without requiring external control modules or specialized training
Solution Approach 2:
The patent replaces complex mechanical control systems (joysticks, pushbuttons, levers) with a sensor-based electronic control system that detects force-induced deformations and translates them into automated actuator commands, simplifying the user interface while maintaining positioning precision
2Adaptability or versatility
If multiple personnel need to control the C-arm in dynamic medical environments, then adaptability improves, but control accuracy and responsibility assignment become problematic
Solution Approach 1:
The C-arm serves multiple functions: it is both the imaging apparatus and the control interface. Any operator can interact with the C-arm by applying force to any part of its structure, making the system universally operable by multiple personnel without requiring different control modules or specialized training for each user
Solution Approach 2:
Sensors continuously detect the deformation of the C-arm caused by operator force and provide real-time feedback to the control device, which adjusts the actuator position accordingly. This closed-loop feedback ensures control accuracy regardless of which operator is manipulating the C-arm or where they apply force
3Adaptability or versatility
If complex movements are required for repositioning in freely positionable systems, then positioning flexibility improves, but the time and skill required to execute movements increase
Solution Approach 1:
The system dynamically responds to operator input by detecting force direction and magnitude through C-arm deformation. The control device automatically determines the appropriate actuator commands based on the detected deformation, enabling complex movements to be executed intuitively and quickly without requiring step-by-step manual control or extensive training

AI summary
An X-ray apparatus is provided. The Xpray apparatus has a C-arm on which an X-ray source and an X-ray detector can be mounted opposite one another, at least one actuator for positioning the C-arm relative to a patient table, and a control device for controlling the actuator. The X-ray apparatus includes at least one sensor which detects a deformation of the C-arm at a first position of the C-arm and converts it into an output signal, the deformation of the C-arm being influenceable by a force exerted by an operator and applied directly or indirectly at a second position on the C-arm. The control device influences the actuator as a function of the output signal of the sensor. A method for controlling the movement of an X-ray apparatus is also described.
