METHOD OF ULTRASOUND TOMOGRAPHY Russian patent published in 2019 - IPC G01N29/04 

FIELD: physics.

SUBSTANCE: usage: for ultrasound tomography. Summary of the invention: placement of piezoelectric arrays of the antenna array on the test object, cyclic ultrasonic irradiation of the test object alternately with each piezoelectric transducer of the antenna array and simultaneous reception of ultrasonic waves and their conversion into electrical signals by all antenna array converters, amplification and conversion into digital codes of the received electrical signals, their preservation, coherent processing of stored digital codes, in which the control object is divided into local areas, which are considered as a local lumped reflecting element, stored digital codes are shifted back in time by an amount, equal to the propagation time of the wave reflected from the local area under consideration to the corresponding piezoelectric transducer of the antenna array, then the time-shifted digital codes are multiplied, respectively, for each of the local areas, the resulting works of digital codes are saved and used to reconstruct the image and visualize it, while after the conversion of ultrasonic waves into electrical signals by all the transducers of the antenna array and their gain, the rate of change of each electrical signal is determined, which is used to calculate the period of conversion of the received electrical signals into digital codes.

EFFECT: technical result: providing the possibility of reducing the amount of data without losing image quality and ensuring the possibility of working in real time.
