echoencephalography

n. a method of mapping brain anatomy for diagnostic purposes by using ultrasonic waves. The waves are transmitted through the skull using an instrument called an echoencephalograph, and echoes of the waves from intracranial structures are recorded to produce a visual image called an echoencephalogram. The method, though still in use, is now considered outdated and has been largely superseded by such methods as transcranial Doppler ultrasonography.
