TRANSCRANIAL ULTRASOUND ABERRATION CORRECTION USING THE CONTralAL MATRIX

摘要

1. A device containing a two-dimensional array of transducers (104, 108) configured to receive transmitted ultrasound (164) transmitted through an inhomogeneous medium (168), the transmitted ultrasound containing ultrasound radiated for reception in the propagation direction, and a processor configured to ( i) the implementation of the assessment of aberration according to the accepted ultrasound, and the implementation takes place in two spatial dimensions of the matrix, so that the assessment of aberration takes into account the transverse aberration in two spaces measurements, and (ii) controlling the ultrasonic operation of the device in accordance with the result of the aberration assessment to improve the ultrasonic operation, the control comprising (a) phase aberration correction and (b) weighting the transmission / reception of the transducer elements / sections. 2. The device according to claim 1, in which the processor is further configured to change, based on the result of the aberration assessment, the settings (220) of the device to provide at least one of a) improving the location of at least one of the ultrasound transmission and reception ultrasound, and b) correcting (512, 528) the formation of an ultrasound beam. 3. The device according to claim 2, in which the processor changes the setting (220, 224) of the device based on at least one of (i) the selected placement of the acoustic window, and (ii) the selected length of the acoustic window. The device according to claim 2, in which the result contains at least one aberration map, for which the elevation (414) and azimuth (413) are independent variables, and the change in the device settings is based on one or more
