Laser Spot Verification via Color Component Shift
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing treatment support systems for cancer photoimmunotherapy struggle to allow operators to accurately verify the correct emission of treatment laser light to the target site while protecting their eyes from the intense laser, as protective glasses block the visible light image, making it difficult to recognize the laser spot.
Innovation Solution
Incorporating a treatment support system with a light source unit that outputs treatment laser light of a specific wavelength and a guide laser light of a lower output, both within the visible spectrum, allowing the guide laser light to be visually recognized on the display device by changing one color component of the treatment laser light in the visible light image, enabling accurate verification of laser emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If protective glasses are worn to block treatment laser light, then operator eye protection is improved, but visual recognition of the laser spot on the display device deteriorates
Solution Approach 1:
A guide laser light source is introduced as an intermediary element that emits visible light at a different wavelength than the treatment laser. This guide light serves as a mediator that allows operators to visually locate the treatment spot while wearing protective glasses that block the treatment laser wavelength. The guide light is superimposed on the treatment target site and appears on the display device, enabling visual confirmation without compromising eye protection.
Solution Approach 2:
The system utilizes different color wavelengths for the guide laser light compared to the treatment laser light. The guide laser operates at a wavelength that appears as a different color to the human eye and is not blocked by the protective glasses designed for the treatment laser wavelength. This color differentiation allows operators to distinguish the guide light from the treatment light and visually confirm proper positioning while maintaining eye safety.
2Reliability
If treatment laser light intensity is increased for effective cancer treatment, then treatment efficacy is improved, but operator safety and visual monitoring deteriorate
Solution Approach 1:
The guide laser light acts as a safe intermediary that provides visual feedback without the harmful effects of high-intensity treatment laser. By separating the functions of treatment (high-intensity laser) and monitoring (visible guide light), the system enables effective cancer treatment while ensuring operator safety and visual confirmation of proper positioning.
Solution Approach 2:
The lighting function is segmented into two distinct components: the treatment laser light for cancer therapy and the guide laser light for visual positioning. This segmentation allows each component to be optimized independently - the treatment laser can maintain high intensity for therapeutic effect while the guide laser provides safe, visible guidance for operator monitoring.

Implementation Method 1
a medical agent including a fluorescent material causing a photochemical reaction... light of a particular wavelength range according to a fluorescent material is emitted. With this, the fluorescence material of the medical agent bound to the cancer cell emits fluorescence and causes a chemical reaction.
Implementation Method 2
the fluorescence material of the medical agent bound to the cancer cell emits fluorescence and causes a chemical reaction. This changes the chemical structure of the fluorescent material.
Implementation Method 3
the fluorescence material of the medical agent bound to the cancer cell emits fluorescence and causes a chemical reaction. This changes the chemical structure of the fluorescent material. This change in the chemical structure of the fluorescent material causes a change in the three-dimensional structure of the antibody.
Implementation Method 4
an imaging unit capable of imaging a visible light image of the treatment target site; and a display device that displays the visible light image

AI summary
This treatment support system is provided with a treatment support device including an image processing unit and a display device for displaying a display image. The image processing unit is configured to output the display image reconstructed by changing one color component corresponding to the treatment laser light in the visible light image to another color component other than the one color component to the display device when treatment of the treatment target site is being performed by the treatment laser light.
