Abstract
I will proceed from the assumption that the readers are familiar with the principles of the application of ultrasound as a diagnostic tool. A mechanical impulse produced by a piezoceramic transducer, which is excited by an electrical impulse, enters the body and is reflected by inhomogeneities within the acoustic field. These reflections are received by the same transmitter and are transformed back into an electrical signal, which is rectified and coded to the intensity of the screen. Moving the weakly focused ultrasound beam, we generate a cross-sectional image of the inhomogeneities of the body. The inhomogeneous structure is therefore very important for the reciprocation of ultrasound. We calculate on the basis of a unique traveling velocity of the impulse and transform the traveling time into a distance [7].
