A study of methods for correcting the location of a focal spot formed by antenna arrays in the form of a spherical segment with different opening angles in a layered-heterogeneous biological environment was made. The use of the mean-thickness sound velocity in biological tissues as a calculation for the matching layer makes it possible to obtain satisfactory results for correcting the location of the focal spot formed by antenna arrays with the opening theta angle of the spherical segment equal to 60, 90 and 120circ. An algorithm for correcting the location of the focal spot based on changes in the physical characteristics of the matching layer is proposed. Keywords: layer thickness averaged speed of sound, focused ultrasound, focal spot, matching layer, control method.
