[Potential use of ultrasonic bioecholocation as a noninvasive method for assessing human intracranial volumetric ratios].
Potential applications of the method of ultrasonic echo location for determining intracranial fluid volume relations are discussed. The data presented give evidence that variations in the attenuation coefficient and propagation pattern of the ultrasonic signal may reflect changes in both hemodynamics and intracranial pressure. Simultaneous invasive investigations may help quantitate ultrasonic echo location results. The review shows that ultrasonic echo location of the brain can be used to determine variations in the intracranial volume relations induced by simulated space flights and to make well documented diagnoses.
