摘要：
FIELD: medicine physics.SUBSTANCE: invention relates to ultrasonic medical diagnostics and can be used for ultrasound examination and evaluation of the state of the brain and its vessels. Method for compensating of distortions in brain images and blood flow in its vessels during transcranial ultrasound examinations involves the formation and transformation of electrical pulses into probing ultrasound signals, scanning of brain structures by them with transceiver multi-element sensor installed in one of the windows of acoustic transparency on the patients head, receiving, converting reflected echoes and forming images based on them, while on the opposite side of the patients head, coaxially with the multielement sensor, the adjusting sensor is placed in the window of acoustic transparency located on the opposite side of the skull by means of the holder and preliminary carry out adjusting the reception including the formation of probing pulses, their radiation in the form of an ultrasonic signal by the calibrating sensor, measurement of delays or phase shifts of the received signals in separate elements of the multielement sensor and storing the measured signals, and / or adjusting the transmission including the formation of probing pulses, alternating emission by separate elements of the multielement sensor, receiving probing pulses from each element of the multi-element sensor with a calibration sensor, measuring and memorizing the mutual differences in delay or phase shift of the signals received by the adjustment sensor. In this case, during the alignment, the phase distortions or signal delays introduced by the cranial bone, measured when aligned to receive a phase or delay in each element of the multielement sensor, or measured during the phase or delay alignment of the signals received by the calibrating sensor during the sequential emission of the probe pulses by each element of the multielement sensor, is compared with the measured value for one of the elemen
