ABSTRACT:
Apparatus and method for the examination of specimens, particularly human tissue in vivo, by pulse-echo ultrasonic methods. To compensate for the variable and unpredictable attenuation of examining signals when reflected from different targets within the specimen, the echoes are processed -- for instance by frequency analysis -- to produce at least two sets of echo-amplitude information. These sets of information are in turn processed to produce a quantity indicative of the attenuation actually undergone by signals in examining each particular target. This quantity may then be applied to the "A" - scan, "B" - scan or other displays of the echoes of the examining signals to compensate them for the effects of varying attenuation. The apparatus may also include similar uncompensated displays and displays directly representing the attenuation co-efficients of the regions of tissue under scan; comparison of these with the compensated displays may reveal further useful information.
