Wireless CT Control Element Positioning and Range Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CT systems with mobile control elements lack flexibility and location independence, as they require fixed positioning for safe operation, restricting access to safety features like emergency shutdown and patient positioning.
Innovation Solution
Implementing a contactless position and range determination system for mobile control elements wirelessly connected to the CT system, allowing control only within a predetermined range to ensure safety regulations are met, using methods like induction loops, cameras, navigation systems, or GPS for precise location monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If simple mechanical encodings are used for location monitoring, then the device complexity is reduced, but the adaptability and location independence are limited
Solution Approach 1:
The patent replaces mechanical encodings with wireless communication technology. The mobile control element communicates its position and control commands wirelessly to the control unit, eliminating the need for mechanical contact or fixed positioning mechanisms. This substitution enables location-independent operation while maintaining system reliability.
Solution Approach 2:
The wireless control element serves multiple functions: it acts as both a control interface and a position indicator. The control unit receives both control commands and position information through the same wireless communication channel, making the system more versatile without adding separate monitoring devices.
2Ease of operation
If fixed positioning is required for control elements, then safety regulations are met, but the ease of operation is reduced
Solution Approach 1:
The mobile control element continuously transmits its position information to the control unit, which monitors whether the control element remains within the predetermined safe range. This feedback mechanism ensures safety regulations are met while allowing the user freedom of movement within the acceptable zone.
Solution Approach 2:
The system transitions from static fixed positioning to dynamic range-based control. Instead of requiring the control element to be locked in a specific position, the system dynamically monitors whether the element remains within the predetermined safe range, allowing flexible movement while maintaining safety.
3Ease of operation
If the control range is extended beyond predetermined distance, then the ease of operation is improved, but harmful factors increase
Solution Approach 1:
The system proactively prevents harmful effects by establishing a predetermined maximum distance before interference with medical devices can occur. The control unit blocks control functions when the mobile control element exceeds this distance, preventing potential interference with pacemakers or other medical implants before it can happen.
