C-arm Movement Path Storage for X-ray Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current X-ray diagnostic apparatuses face challenges in accurately reproducing manual movements of C-arms, as they do not acquire the movement path during auto-positioning, leading to unpredictable movements and increased operational effort for medical professionals.
Innovation Solution
The X-ray diagnostic apparatus includes a memory and processing circuitry that stores and reproduces the movement path of the C-arm by combining movements of its movable shafts, allowing the apparatus to move in the reverse order of the stored path, thereby enabling precise reproduction of manual movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If auto-positioning is used to move the C-arm to a pre-registered position, then the movement can be automated, but the movement path cannot be uniquely reproduced and may result in unexpected movements
Solution Approach 1:
The system performs preliminary action by storing the movement path data when the C-arm is manually moved to a target position. This stored path information is then used in subsequent operations to automatically reproduce the exact same movement path, eliminating the need for re-registration and ensuring consistent, reliable path reproduction across multiple operations.
2Ease of operation
If manual operation of the C-arm is performed without pre-registering the position, then operational flexibility is maintained, but returning to the original position requires complicated operations
Solution Approach 1:
The system creates a copy of the movement path by storing the sequence of positions and movements when the C-arm is manually operated. This copied path information is then used to automatically guide the C-arm back to the original position, replacing complicated manual return operations with simple automated reproduction of the stored path in reverse.
3Measurement precision
If pre-registration of movement positions is required for auto-positioning, then position accuracy is improved, but operational effort and complexity increase
Solution Approach 1:
The system performs self-service by automatically capturing and storing the movement path data during manual C-arm operation. The stored path information is then used to automate subsequent positioning operations, eliminating the need for manual pre-registration and reducing operational complexity while maintaining high position accuracy through the reproduced path.

AI summary
In one embodiment, an X-ray diagnostic apparatus includes a memory and processing circuitry. The processing circuitry causes the memory to store a movement path that is defined by a combination of movements of a plurality of movable shafts of an imaging apparatus and is generated based on movements of the imaging apparatus in response to a user's operation. The processing circuitry moves the imaging apparatus in a reverse order of the movement path stored in the memory.
