Abstract
An ultrasonic method for indicating a characteristic of intraparenchymal brain tissue includes the transmission of broadband ultrasound from a transmitting transducer positioned on one side of a patient's cranium to a receiving transducer located on another side of the cranium with decomposition of the received signal into narrowband components and determination therefrom of group delay, phase angle and attenuation as a basis for derivation of the characteristic of the intraparenchymal tissue within the cranium.
