HSI-Plus

OPTIS, software and hardware vendor for scientific simulation and measurement of light and materials, today announces their involvement in the HSI-Plus project and offers its unique know-how in research against skin cancer. 

 

For skin cancer screening, biopsies are now based on visual controls and the experience of high performing physicians. The HSI-Plus project aims to develop an imaging measurement system for the objective detection of precancerous lesions of the skin. Two technologies are combined for this purpose. First, structured lighting is used to obtain depth resolution and to filter the disturbing signal components of the lower layers of fibrous tissue. Then, a multifocal hyperspectral camera system is intended to map cellular changes by spatially resolving the detection of the skin’s optical properties.

 MEASURING THE OPTICAL PROPERTIES OF THE SKIN

To enable the medical industry to detect cancerous skin lesions earlier, project participants must create a device to measure different types of skins.

 

“Skin is a complex element to measure as the propagation and diffusion of light in the skin’s different layers are so far impossible to characterize, to measure and thus to simulate. This is why measurements are exclusively made on silicone samples. Add to that the fact that the current material measuring devices do not allow to measure too large samples, like a whole face for example. These are the challenges of the project!”

said Jacques Delacour, CEO & Founder of the OPTIS Company.

 

However, OPTIS - the virtual prototyping company specialized in the simulation of light and human vision based on the physics laws of optics - counts in the umbrella of its offer the OMS4, a color and light scanner that enables to capture unique appearance variation under different illumination. Their goal by taking part to this project is to help develop a new device, meant to measure different types of skins, based on this existing material and color scanner and OPTIS’ 28 years of experience in the analysis of light behavior.

 

 “To enhance the project, OPTIS will use their know-how in light and material measurement, and the current OMS4 to calibrate the new measuring device. By participating in the HSI-Plus project, we support the ILM – Institute for Laser Medicin - who is doing research step by step with our feedback so that the outcoming device is really answering the needs from industry”.

comments Günther HASNA, Strategic Project Director at OPTIS for the HIS-Plus project.

 

 

In the end, these skin measurements will give rise to 3D prints, notably thanks to the creation of an artificial skin library.

 

“The challenge is great but so are the rewards! With the support of many partners such as ILM, SPECTARIS, and FOM we have at heart to make this project possible, and advance research against skin cancer”

concludes HASNA. The end of the project is scheduled for January 2020.

About the HSI-plus Project

Structured illumination and hyperspectral imaging as a novel approach to tumor detection in dermatology. For skin cancer screening, biopsies today are mostly based on visual controls and on the experience of the performing physicians. The project aims to develop an imaging measuring system for the objective detection of premalignant lesions of the skin. Two technologies are combined for this purpose: Structured illumination is used to achieve a depth resolution and to filter out disturbing signal components from lower tissue layers. A multifocal hyperspectral camera system is intended to map cell changes by spatially resolved detection of optical skin properties. The involved research institutions and companies are:
