📋 Aleph Neuro • Butterfly Network • Non-Invasive Brain Imaging • 6 min read

🧫 Watch: Scientists from Aleph Neuro have achieved the highest-resolution 3D imaging of a living human brain using ultrasound and microbubbles.

🧠 What Is This Breakthrough?

Scientists from Aleph Neuro, a US-based research laboratory, have achieved a historic milestone: the first-ever 3D image of a living human brain with the highest resolution ever attained without opening the skull.

The breakthrough uses ultrasound passing through the intact skull combined with microbubbles as a contrast agent to create detailed vascular maps of the brain.

🧬

Non-Invasive

No skull opening required

🔬

100x Higher Resolution

Than comparable methods

📱

Portable Technology

Smartphone-sized device

💡 Key Innovation: The technology uses neurovascular ultrasound to track blood flow through signals reflected from red blood cells — capturing changes in blood flow when neurons are activated.

⚙️ How the Technology Works

🩸

1. Neurovascular Ultrasound

Tracks blood flow in the brain through signals reflected from red blood cells. When neurons are activated, blood flow increases — and these changes are captured in real-time.

🫧

2. Microbubbles as Contrast Agent

Scientists solved the problem of ultrasound scattering by the skull using microbubbles, which allow precise 3D mapping of the brain’s blood supply.

🧩

3. 3D Vascular Mapping

The technology constructs a three-dimensional map of the brain’s blood supply with resolution 100 times higher than comparable imaging methods.

🔗 Technology Partner: The device is built on an ultrasound chip from Butterfly Network, which is already used in portable medical ultrasound scanners the size of a smartphone.
