Microwave-Transparent Examination Marker for Accurate Probe Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In microwave diagnostic imaging, such as microwave mammography, the accuracy of three-dimensional image generation is compromised due to variable scan distances and potential misses or duplications caused by manual scanning with a probe, leading to reduced diagnostic imaging accuracy.
Innovation Solution
An examination marker with a marker body that adheres to the examination site, displaying a microwave-transmissive index and deforming to fit the site's shape, ensuring accurate scanning by guiding the operator and maintaining high microwave transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If manual scanning with a probe is performed, then the examination can be conducted without compression and without X-ray radiation, but the scanned distances vary and scans may be missed or duplicated, reducing image accuracy
Solution Approach 1:
An examination marker is introduced as an intermediary tool between the probe and the breast tissue. The marker includes a base film with a scan index that guides the operator's scanning movements, ensuring consistent scan distances and preventing missed or duplicated scans while maintaining the microwave-based non-ionizing examination method
2Measurement precision
If a marker body is added to guide scanning, then scan accuracy improves, but the device complexity increases
Solution Approach 1:
The marker uses a thin, flexible base film that can conform to the breast surface without adding significant structural complexity. The scan index is printed directly on this simple film structure, providing guidance functionality while maintaining ease of use and minimal interference with microwave transmission
Solution Approach 2:
The examination marker is designed to be self-adhering to the breast surface through the properties of the base film, eliminating the need for additional complex attachment mechanisms. The marker automatically positions and maintains itself during the scanning process
3Illumination intensity
If the marker body material is made opaque for visibility, then the index can be clearly displayed, but microwave transmission is attenuated
Solution Approach 1:
The scan index is displayed using color printing or coloring on the base film. The base film itself remains transparent or translucent to allow microwave transmission, while the colored index provides visual guidance. This separates the visibility function (color) from the transmission function (transparent material)
