发明名称 METHOD AND DEVICE FOR ULTRASONIC MEASUREMENTS
摘要 <p>According to the invention, it is provided an ultrasonic measurement method wherein an ultrasonic transducer (102; 230; 502) is acoustically coupled to an object (101; 217; 501) to be measured by means of a resilient material contact layer (218). The transducer (102; 230; 502) transmits a plurality of consecutive ultrasonic transmit signals into the said object (101; 217; 501) being measured, the transmit frequency (f ) of each of said plurality of transmit signals being distinct from the frequency of the other transmit signals of said plurality of transmit signals. Signal echoes of said transmitted signals are received, and based on the said received signal echoes, at least one transmit frequency (f) to be used for ultrasonic measurement of the said object (101; 217; 501) is selected. The invention also relates to an ultrasonic measurement device.</p>
