Abstract
The non-invasive testing of soft body tissue is accomplished with the use of a beam of ultrasonic energy which may be focused at varying depths in a patient. The energy content of the ultrasound beam is varied as a function of depth of focus to thereby employ the minimum energy required for proper resolution at the chosen examination depth. Signals commensurate with echoes received by a transducer having an array of coaxial annular electrodes thereon are combined in a manner which results in a good signal-to-noise ratio and minimum attenuation thereby improving the quality of the information derived from the examination procedure.
