C-arm Collision Recovery via Position Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In X-ray imaging systems, collisions between the movable C-arm and patient table are difficult to recover from, requiring on-site service and causing time-consuming disruptions, especially during procedures like surgery.
Innovation Solution
A collision recovery system that automatically records and retraces the C-arm and patient table positions using a position tracking processor and user interface, allowing users to revert to a valid stationary position from an invalid one, enabling manual or automatic path retracement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user manually maneuvers the C-arm to avoid collision, then the system can maintain operational flexibility, but the complexity of operation increases and time is lost during recovery
Solution Approach 1:
The system continuously records the C-arm position and movement path in advance before a collision occurs. When a collision is detected, the pre-recorded path data enables automatic retracement to the last valid position, eliminating the need for manual maneuvering and significantly reducing recovery time.
Solution Approach 2:
The system automatically detects collisions through position monitoring and initiates self-recovery by retracing the recorded path without requiring user intervention or on-site service engineer assistance. The system serves itself by using the stored position data to autonomously return to a valid operational state.
2Reliability
If the system continuously tracks and stores C-arm position data, then collision recovery capability is improved, but device complexity increases
Solution Approach 1:
The position tracking and data storage system serves multiple functions: it monitors C-arm position in real-time, records movement paths for later retrieval, detects collision conditions, and enables automatic recovery. This multi-functionality justifies the added complexity by providing comprehensive collision prevention and recovery capabilities.

AI summary
A system provides recovery from an X-ray system C-arm and patient table collision. A collision recovery system enables a user to recover from a collision or near collision of movable components of an X-ray imaging system including a movable C-arm hosting an X-ray emitter and detector. The system includes a C-arm position tracking processor for automatically recording C-arm position data indicating a valid stationary position of a C-arm and a path from the valid stationary position to an invalid position of the C-arm enabling retracement of the C-arm along the path to the valid stationary position. A user interface enables a user to initiate retracement of the C-arm along the path to the valid stationary position. A C-arm is movable to retrace the path to the valid stationary position using the recorded C-arm data in response to user command.
