FIELD: physics.
SUBSTANCE: invention can be used to correct phase distortions in signals during transcranial ultrasonic imaging. Essence of the invention is that when focusing is performed, additional delays approximated by a polynomial are introduced, the amplitude and order of which are selected to achieve the best correction of phase aberrations.
EFFECT: possibility of improving image quality.
