摘要：

Evidence is given to show that an ultrasonic transmitter has its beam widely and irregularly scattered by the living skull and brain and that the pattern of this irregular scattering varies greatly with small movements of the transducer relative to the skull. Thus, it is not justifiable to identify the source of echoes with interfaces lying in the transducer axis on the assumption that adequate insonation for echo formation will only be received by interfaces in and near the transducer axis. © 1969 International Federation for Medical and Biological Engineering.
