Title:
ULTRASONIC DIAGNOSTIC APPARATUS
Document Type and Number:
Japanese Patent JPS60116345
Kind Code:
A
Abstract:
Apparatus using reflected ultrasonic waves for discriminating a characteristic property of a medium (e.g. tissue) to be observed is provided. The apparatus obtains information from the reflected waves concerning the nature of fine structure of the medium. More practically the interval between small reflecting bodies dispersely distributed in the medium is determined as a characterising parameter. In practice the small reflecting bodies are distributed at a variety of intervals in the medium. The apparatus provides a means for calculating an average value of the intervals and/or an indication of the amount of variation or fluctuation of the intervals and for displaying the result of calculation. The apparatus may use the cepstrum of a receiving signal corresponding to the reflected ultrasonic wave, or may use self-correlation of the receiving signal to obtain an average value of the intervals.
