Investigational · VNU project QG.24.84 · Device not yet licensed. This is a screening-support tool; the result is an AI-estimated risk indicator — not a diagnosis and not a substitute for a physician. The device is under research.
Overview — Thin-Client architecture
A sealed enclosure houses the sensitive optics–electronics; wireless control via iPad; detachable RPB-785 probe; non-invasive spectral analysis; cloud sync + physician review portal.
