Measuring blood flow in the brain.
We are building a compact optical sensor intended to measure it from outside the head.
02 / What we are building
A compact optical sensor for cerebral blood flow.
Rhyos is an early-stage company. We are working on a sensor intended to measure blood flow in the brain from outside the head, without a scanner or an implanted probe.
We want to measure flow itself, rather than oxygenation as an indirect measure. The work is in development and pre-market. Nothing is for sale, and we are not making a clinical claim.
03 / How it may work
Light, motion, and depth.
The technical idea combines near-infrared light and interferometry. The aim is to recover flow at different depths and distinguish brain signals from the scalp.
- 01
Light in
Near-infrared light is sent into tissue from outside the head.
- 02
Signal out
Interference in the returning light carries information about moving blood cells.
- 03
Separate depth
The intended method separates shallower scalp signals from deeper brain signals.
The method has been tested on the bench and in tissue-like models. Building the compact instrument and validating its measurements are the next parts of the work.
04 / Current focus
Build the instrument. Test the signal. Compare it carefully.
We are reducing technical and practical uncertainty one step at a time.
05 / Team
Cas and Quinten are building Rhyos.
We are an early team of two, building the instrument and the company together. We try to be clear about what has been shown and what still needs testing.
