Researchers at Augusta University in Georgia, US are developing a portable 3D ultrasound device to examine the optic nerve for cranial damage. While ultrasound can't look directly into the brain because bone and distance deter ultrasound waves, the new device examines the sheath that protects the optic nerve for distortions that indicate increased pressure in the skull. By using an accelerometer to measure motion, and a gyrometer to gauge position, the Inertial Measurement Unit technology takes images from different angles to form a 3D model of the brain.
