Integrated Camera Head for Simultaneous Skin Diagnosis and Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional skin diagnosis apparatuses are inefficient in simultaneously performing photodynamic diagnosis and therapy, as they often require separate devices for fluorescence diagnosis and photodynamic therapy, and lack the ability to accurately analyze skin conditions using both fluorescence and white light simultaneously, leading to poor image quality and limited depth of skin diagnosis.
Innovation Solution
A system comprising a camera head with a white light source, a digital color TV camera, and a light source system connected through a light guide, which allows for simultaneous irradiation and analysis of skin regions with white light, fluorescence excitation light, and therapeutic light, enabling the capture and processing of color and fluorescence images, along with synthesized images for improved diagnostic efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate devices are used for fluorescence diagnosis and photodynamic therapy, then each device can be optimized for its specific function, but the overall diagnostic efficiency and treatment integration are reduced
Solution Approach 1:
The patent combines fluorescence diagnosis and photodynamic therapy functions into a single integrated apparatus. The device includes both a fluorescence detection system with camera and filter, and a photodynamic therapy light source system that can be used sequentially on the same skin region, eliminating the need for separate devices and improving workflow efficiency
Solution Approach 2:
The apparatus is designed to perform multiple functions: fluorescence imaging for diagnosis, white light imaging for reference, and photodynamic therapy. The light source system can switch between different wavelengths and modes to accommodate both diagnostic and therapeutic requirements, making the device universally applicable for multiple skin condition management tasks
2Measurement precision
If only fluorescence imaging is used for skin diagnosis, then specific skin conditions can be detected, but the overall image quality and diagnostic depth are limited
Solution Approach 1:
The apparatus merges fluorescence imaging with white light imaging capabilities. The camera system can capture both fluorescence signals (using specific filters) and white light reference images, allowing simultaneous acquisition of multiple types of information from the same skin region, thereby improving overall image quality and diagnostic information completeness
Solution Approach 2:
The device provides different imaging modes for different diagnostic needs: fluorescence mode for detecting specific skin conditions with high precision, and white light mode for overall skin appearance and morphology. Each mode optimizes image quality for its specific purpose, and both can be used together for comprehensive diagnosis
