Abstract. Soft
tissue displacement measurement techniques are important part of elasticity
imaging technologies. Accuracy of the techniques defines elasticity imaging
performance. The paper presents small displacement measurement technique, which
can be realized using ultrasonic medical scanner hardware. The technique can be
used for very small tissue displacement detection and measurement downward to
several nanometers. To study the technique main properties and test their performance,
experimental setup was created by the authors. The setup detailed description
is presented in the paper. The setup contains modified medium performance
ultrasonic scanner prototype equipped with 7.5 MHz linear probe, ultrasound
phantom and linear actuator. The results of the technique testing are
presented.
Key words:
ultrasound, displacement measurement, ultrasonic scanner.
