The OEG-Spectratech SpO2 is the latest breakthrough in optical imaging to visualize brain function. The device measures hemoglobin levels in the brain and the amount of oxygen being transported. The equipment to measure brain functions developed so far used the light to check for changes in hemoglobin, but it was impossible to detect oxygen levels in the arteries of the brain simultaneously.

"The arterial oxygen saturation is a very weak signal. This is a sensor that picks up signals that travel through the brain. In high sensitivity, the relationship between signal and noise is extremely low. To solve this problem, we had to modulate the spectrum used to ensure the proper functioning of the signal. We are a small company and would like to market this product in Japan and then abroad, "says the leader of the team of developers, Mitsuo Ohashi.

The system is used to show the difference in blood flow and oxygen levels when the patient is relaxed or in situations of concentration.

The device makes it possible to analyze the changes of hemoglobin and the amount of oxygen carried through the arteries. We hope that this will lead to advances in research on brain function, including cerebral circulation and metabolism.

The demonstration of the equipment can be seen in the video below.
