Annular Scanning Device for Optical Tomography with Adjustable Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical tomography scanning and imaging systems face reduced accuracy due to a fixed distance between optical channel modules and the object being examined, which is not adjustable, affecting the examination results regardless of the object's size, and may cause discomfort during the examination process.
Innovation Solution
An annular scanning device with a rotating member and adjustable optical channel modules, allowing for rapid assembly and disassembly, non-contact or slight contact measurement, and precise distance adjustment between the modules and the object, facilitated by a carrying base with guiding grooves and positioning openings, and a driving module for rotating the member to adjust the optical channel assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the distance between optical channel modules and breasts is fixed, then the system structure is simple, but the examination accuracy is reduced when breast size varies
Solution Approach 1:
The patent implements a movable optical channel module that can adjust its distance from the breast along the optical axis. The module is positioned on a movable platform that can be controlled to move closer or farther from the breast, allowing the system to adapt to different breast sizes and maintain optimal examination accuracy without requiring a complex reconfigurable structure
Solution Approach 2:
The movable optical channel module serves multiple functions: it can adjust its position to accommodate different breast sizes, maintain optimal scanning distance for various patients, and provide consistent examination quality across different anatomical variations. This single adjustable component replaces what would otherwise require multiple fixed-position modules
2Adaptability or versatility
If multiple optical channel modules are used to scan breasts, then the scanning capability is improved, but the distance adjustment capability is lost
Solution Approach 1:
The patent combines multiple optical channel modules into a single integrated movable unit that can adjust its position collectively. This merged structure allows all optical channels to maintain consistent spacing from the breast while providing unified distance adjustment capability, simplifying the operation compared to individually adjusting multiple separate modules
3Measurement precision
If the optical channel modules are fixed at a certain distance, then the system structure is stable, but the examination results are influenced when breast size varies
Solution Approach 1:
The optical channel module is mounted on a movable platform that enables dynamic adjustment of the scanning distance along the optical axis. This dynamic positioning system allows the module to maintain a consistent, optimized distance from the breast regardless of breast size variations, ensuring examination result consistency without requiring multiple fixed-position systems

AI summary
The present invention relates to an annular scanning device for optical tomography scanning and imaging system, which comprises a carrying base, a rotating member, a plurality of optical channel modules, and a driving module. The rotating member is disposed on the carrying base. The plurality of optical channel modules are disposed annularly on the rotating member and connected to the rotating member. When the driving module drives the rotating member to rotate, a plurality of optical channel assemblies of the plurality of optical channel modules move towards or away from the center of the rotating member for adjusting the distance between the plurality of optical channel assemblies and an object under test.
