The effect on the imaging quality of the frequency of the ultrasound wave transmitted from the ultrasound probe in the Doppler tomography method

Doppler tomography (DT) is a method that allows the reconstruction of 2D or 3D images of the inside of the examined object. For this purpose, a two-transducer ultrasound probe is used. In this method, the Doppler phenomenon and the so-called Doppler signal are used to obtain an image. Therefore, the probe is one of the most important components of the measurement system of this method. It should be noted that Doppler tomography differs significantly from the well-known Doppler method of measuring blood flow in blood vessels. In the DT method, stationary cross-sectional images of the object under examination are obtained. In order to produce the Doppler effect in this case, the probe can move around or along the object being imaged. This paper will present a simulation of the effect of the frequency of ultrasonic wave generated by the ultrasound probe on the imaging quality for a single inclusion.
