C-Arm Bendable Connection for Detector Support Bulk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing rigid and straight connection between the radiation detector support and the C-shaped structure in medical imaging systems limits the object image distance when the C-arm rotates, as it projects beyond the C-shaped structure, risking interference with the floor and restricting the use of maximum object image distances.
Innovation Solution
A bendable connection between the radiation detector support and the C-shaped structure, utilizing a chain of articulated links that can be stored within the structure, allowing the connection to reduce its bulk and project minimally when the C-arm rotates, enabling maximum object image distances without interference.

1Reliability
If a rigid and straight connection is used to link the radiation detector support to the C-shaped structure, then the connection maintains structural stability and alignment, but the connection projects beyond the C-shaped structure when the object image distance is set to maximum, risking interference with the floor and limiting the use of maximum object image distances
Solution Approach 1:
The connection is transformed from a rigid straight structure to a dynamic articulated chain that can change its configuration. The chain adapts its shape based on the support position: when the support is retracted, the chain folds back along the C-shaped structure; when the support is extended to maximum object image distance, the chain extends outward. This dynamic behavior eliminates the need for a permanently extended rigid connection, preventing floor interference while maintaining structural stability during imaging operations.
2Volume of moving object
If the connection is made bendable to reduce its bulk, then the connection can be stored within the C-shaped structure and does not project beyond the end, but the connection must be articulated rather than rigid
Solution Approach 1:
The connection is divided into multiple articulated links rather than being a single rigid element. This segmentation allows the connection to fold and store within the C-shaped structure when the support is retracted, minimizing projection beyond the end. The articulated joints maintain sufficient structural strength to support the radiation detector during imaging operations, resolving the contradiction between compact storage and load-bearing capability.
Solution Approach 2:
The articulated chain connection is designed to nest within the C-shaped structure when the radiation detector support is in its retracted position. The chain folds back along the contour of the C-shaped structure, with links nesting within the available space, minimizing the overall projection beyond the end of the C-shaped structure while maintaining access to maximum object image distance when extended.
