摘要： PROBLEM TO BE SOLVED: To improve the distance resolution and azimuth resolution of an ultrasonography.SOLUTION: In a circuit 14 for processing received ultrasonic signals, a component of the same basic frequency f1 as the transmission pulse is extracted with a correlation part F1 composed of a matched filter, and components of harmonic waves f2, f3, ... generated from non-linear distortion of a subject are extracted by one or a plurality of band pass filters F2, F3, .... The extracted components are added after multiplying prescribed coefficients k1, k2, ... by coefficient multipliers K1, K2, ... to be used for the image processing. Accordingly, the signal-to-noise ratio can be improved by subjecting the basic frequency component to the correlation process, and the capability of detecting signals can be improved by the pulse compression effect. At the same time, the penetration (the distance resolution in the depth) can be improved and the contrast to noise can be also improved. Only the basic frequency component permitting use of the transmission signal itself as a reference signal is subjected to the correlation processing, while conventional band pass filters which can be easily prepared are used for harmonic waves, so that the azimuth resolution can be also improved.

摘要： PROBLEM TO BE SOLVED: To provide a harmonic separating technique which adopts an inexpensive filter with a simple circuit construction and relatively large transition region and which leads to adoption of an AD converter of a low sampling frequency by increasing the frequency ratio between adjacent two basic fundamental wave and harmonic or between two harmonics, because, by a filter method, the fact that the frequency ratio between two adjacent fundamental wave and harmonic or between harmonics is low complicates the circuit, leads to higher noise, higher power consumption, higher costs of the filter or the like and further inevitably needs adoption of a high-cost AD converter because the strength of signals of separated frequency components of harmonic should be sampled.
SOLUTION: Locally-generated waves are mixed with reception signals of a piezoelectric element and frequency of the reception signals is down-converted.
