Presentations at Photonics West 2021 Show How Early-Stage Imaging System's Flexibility Can Be Applied Broadly in Medical Field
Employing recent developments in photonics components, which allow using infrared light to detect abnormal tissues, mid-IR imaging can provide unequivocal information about the biochemical composition of human cells, said Grégoire Mathieu, lead author of the first paper. The combination of a set of lasers and lensless imaging with an uncooled bolometer matrix allows biochemical mapping over a wide field of view. The project showed that this experiment's setup coupled to machine learning algorithms (Random Forest, Neural Networks, K-means) can help to classify the biological cells in a fast and reproducible way.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
