POC Device Pairs Optics, Ultrasound to Improve Thyroid Screening
CASTELLDEFELS, Spain, June 29, 2021 — An EU-funded development project for detecting thyroid cancer has produced an optical device that could give doctors a reliable, low-cost way to determine whether a thyroid nodule is malignant or benign. The five-year project, named Laser and Ultrasound Co-analyzer for Thyroid Nodules (LUCA), was coordinated by Spain’s ICFO photonics research center. The different technologies of LUCA are embedded in a single portable device. It is a multimodal platform that combines near-infrared
