Multi-Turntable Adaptor for CT System Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CT systems face limitations in throughput for scanning strong absorbing or high contrast objects, as simultaneous acquisition is not feasible due to exceeding penetration capabilities, requiring complex mechanical and software adaptations for multi-turntable systems.
Innovation Solution
A mechanically coupled multi-turntable adaptor for CT systems, which includes at least two object turntables coupled by a coupler and a rotation transmission element, allowing simultaneous rotation and increasing throughput without extensive hardware or software modifications, using a belt or gear wheels for mechanical coupling and a rod for rotation transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple objects are placed on a single turntable for simultaneous acquisition, then throughput increases, but penetration capability is exceeded for strong absorbing objects
Solution Approach 1:
The patent divides a single turntable into multiple separate turntables (first turntable and second turntable), each capable of independently rotating and holding separate objects. This segmentation allows multiple objects to be scanned simultaneously without exceeding the penetration capability of the X-ray device, as each object receives dedicated X-ray beam coverage.
Solution Approach 2:
The patent transitions from a single-plane turntable configuration to a multi-plane spatial arrangement with multiple turntables positioned at different locations within the X-ray beam path. This dimensional expansion enables parallel processing of multiple objects while maintaining adequate X-ray penetration for each individual object.
2Productivity
If separate turntables are used for each object to maintain penetration capability, then throughput increases, but mechanical and software adaptations become complex
Solution Approach 1:
The patent combines multiple turntables into a single integrated adaptor assembly that functions as one cohesive unit. The first and second turntables are mechanically coupled through a common adaptor structure, allowing them to rotate in coordination without requiring separate control systems. This merging approach simplifies the overall system architecture while maintaining the throughput benefits of multiple objects.
Solution Approach 2:
The adaptor is designed as a universal interface that can be mounted on standard CT system turntables, making it compatible with existing CT devices without requiring custom mechanical modifications. The adaptor handles multiple functions including supporting multiple turntables, coordinating their rotation, and interfacing with the existing CT system control software.
3Productivity
If an integrated Multi-Turntable system is installed by the vendor, then throughput optimization is achieved, but large efforts in mechanical, electrical and software adaptations are required
Solution Approach 1:
The patent extracts the multi-turntable functionality from the core CT system by providing it as a separate, removable adaptor that can be independently manufactured and installed. This extraction allows the adaptor to be produced and tested independently, then installed on existing CT systems without requiring the vendor to perform complex integrated modifications to the main system architecture.
Solution Approach 2:
The adaptor serves as an intermediary component between the existing CT system turntable and the multiple object scanning capability. It provides the multi-turntable functionality while interfacing with the existing system through standard mounting interfaces, thereby avoiding the need for direct modifications to the CT system's mechanical, electrical, or software architecture.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adaptor enhances CT system throughput by enabling simultaneous scanning of multiple objects without additional mechanical or electrical integration efforts, maintaining system stability and image quality through precise alignment and counter-rotation mechanisms, allowing for efficient reconstruction of CT models from multiple objects.
Implementation Method 1
