Radiography Image Stabilizer for Stable Pipe Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional C-arm radiography devices face instability issues during imaging and are limited in orientation when suspended, particularly in applications like pipe-under-insulation scanning.
Innovation Solution
The implementation of an image stabilizer attached to a digital radiography system, featuring legs with low-friction surfaces and adjustable pivot points, allowing for stabilization and consistent height and angle maintenance during scanning of pipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hand-carried radiography device is used, then portability is improved, but image stability deteriorates
Solution Approach 1:
An image stabilizer device is introduced as an intermediary between the hand-carried radiography device and the patient's body. The stabilizer includes a support structure with contact surfaces that rest on the patient, providing external support to counteract hand-held instability while maintaining portability benefits
2Stability of the object's composition
If suspended radiography device is used, then image stability is improved, but adaptability to different orientations deteriorates
Solution Approach 1:
The image stabilizer employs adjustable components including extendable legs with locking mechanisms and rotatable contact surfaces. These dynamic features allow the device to adapt to various orientations (axial, radial, oblique) and different pipe diameters while maintaining image stability during fluoroscopic procedures
3Device complexity
If fixed-orientation radiography system is used, then device complexity is reduced, but adaptability to varying pipe diameters deteriorates
Solution Approach 1:
The image stabilizer is divided into modular segments including adjustable legs, rotatable contact surfaces, and detachable components. This segmentation allows independent adjustment of each component to match different pipe diameters and orientations without requiring complete system redesign
Solution Approach 2:
The device incorporates adjustable parameters including leg length, contact surface angle, and positioning height. These parameters can be modified to accommodate varying pipe diameters and insulation thicknesses, providing adaptability while maintaining relatively simple device architecture

AI summary
Example radiography image stabilizers include: an attachment bracket configured to be coupled to a center section of a radiographic imaging device and to extend from the center section of the imaging device in a first direction different than a direction in which the imaging device is configured to direct radiation; two or more legs attached to the attachment bracket and configured to extend from the bracket at least partially in the directions in which the center section of the imaging device extends from an attachment point with the bracket; and three or more low-friction contact surfaces collectively coupled to the two or more legs, such that at least one contact surface is disposed on each side of the center section, wherein the legs include pivot points and leg sections to selectively adjust a height of the bracket with respect to the contact surfaces and a width between the contact surfaces.
