CURVED ULTRASONIC HIFU-CONVERTER WITH PRELIMINARILY FORMED SPHERICAL ADJUSTMENT LAYER Russian patent published in 2015 - IPC A61B8/00 B06B1/06 G10K11/00 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, namely to diagnostic ultrasound systems. Curved converter of high-intensity focused ultrasound (HIFU) contains curved piezoelectric matrix, which has opposite convex and concave surfaces, with concave surface being transmitting surface, and multitude of zones of acoustic transmission. Multitude of electrodes is located on surfaces of curved piezoelectric matrix. Curved adjustment layer, formed in monolithic, continuous way, is formed with required curvature of curves matrix of converters, and is attached to transmitting surface. Printed circuit board and back plate are located on side of matrix, opposite to adjustment layer, with back plate limiting air channel between printed circuit board and plate, and printed circuit board limits air channel between printed circuit board and matrix.

EFFECT: application of invention makes it possible to facilitate giving required shape to converter.
