ULTRASOUND TOMOGRAPHY DEVICE Russian patent published in 2024 - IPC G01N29/04 

FIELD: physics.

SUBSTANCE: use for ultrasonic tomography. Essence of the invention consists in the fact that ultrasonic tomography device has a flexible antenna array with n receiving-transmitting elements mounted tightly on a flat or curvilinear external surface of the test object located in an immersion bath. Each receiving-transmitting element is connected to the output of the corresponding pulse generator and to the input of the corresponding chain of series-connected amplifier and analogue-to-digital converter, output of each of the n specified chains is connected to the corresponding input of the memory unit of realizations, the number of outputs of which N is determined by the formula: N=n⋅(n+1)/2. Outputs of the implementation memory unit are connected to the corresponding inputs of the computing unit, which is connected to the storage memory unit and to the display through the image memory unit. Synchronization inputs of each pulse generator, implementation memory unit, computing unit and image memory unit are connected to corresponding outputs of the synchronization unit. Acoustic sensor is installed on the back side of the flexible antenna array so that it is immersed in the immersion liquid, and the flexible antenna array is completely located in its acoustic field. Acoustic sensor is connected to an amplifier, the output of which is connected to the first input of the comparator, the second input of which is connected to a reference voltage source. According to the invention, on the back side of the flexible antenna array, two more acoustic sensors are additionally installed, wherein all acoustic sensors are located at the vertices of an arbitrary triangle on a plate attached to a bracket at the edge of the immersion bath so that they are immersed in the immersion liquid, and the flexible antenna array is completely located in their acoustic field. Each acoustic sensor is connected in series to an amplifier, the first input of the comparator, a time interval meter and to a unit for calculating coordinates. Second input of each comparator is connected to the reference voltage source. Each time interval meter is connected to the synchronization unit and to the output of the logic adder, the inputs of which are connected to the inputs of the pulse generators and the inputs of the coordinate calculation unit, which is connected to the computing unit.

EFFECT: providing the possibility of reliable determination of coordinates of elements of a flexible antenna array and, accordingly, reliable reconstruction of a tomogram.
