Mobile Control Device for Medical Imaging Transfer Plate Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical imaging devices, such as CT and MR devices, face challenges in patient positioning due to the need for precise alignment of the transfer plate with the gantry, which is often limited by the fixed control elements on the gantry, restricting user mobility and flexibility, especially in emergency situations or culturally sensitive contexts.
Innovation Solution
A mobile control device with an electromechanical switching element, a control unit, and a pose determination unit that allows for remote and flexible control of the transfer plate's movement, enabling users to position the plate from various angles and distances, using a touch-sensitive surface and audio interface for user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If controls are permanently mounted on the gantry, then precise positioning of the transfer plate can be achieved, but user mobility and flexibility are restricted
Solution Approach 1:
The control elements are extracted from the fixed gantry structure and implemented as a mobile control device that can be moved freely throughout the examination room, eliminating the restriction of fixed positioning while maintaining control functionality
Solution Approach 2:
A mobile control device serves as an intermediary between the user and the transfer plate positioning system, receiving user input and transmitting control signals to position the transfer plate precisely without requiring the user to be adjacent to the gantry
2Ease of operation
If controls are distributed across multiple locations on the gantry, then accessibility is improved, but device complexity and costs increase
Solution Approach 1:
The mobile control device consolidates multiple control functions into a single portable unit that can be positioned anywhere in the examination room, providing universal access to all transfer plate positioning controls without requiring multiple fixed control stations
Solution Approach 2:
Multiple control elements that would traditionally be distributed across the gantry are merged into a single mobile control device, reducing system complexity while maintaining accessibility through the device's mobility
3Device complexity
If controls are fixed on the gantry, then system simplicity is maintained, but response time in emergency situations is increased
Solution Approach 1:
The control system transitions from a static fixed-gantry configuration to a dynamic mobile control device that can be rapidly repositioned, enabling faster response to emergency situations while maintaining operational simplicity through the unified control interface
