摘要：
FIELD: medicine.SUBSTANCE: group of inventions relates to medical technology, namely to the ultrasound surgery devices. Device for creating high-intensity focused ultrasonic fields for non-invasive local destruction of biological tissue is a phased lattice with a random arrangement of radiating elements in the form of polygons, areas of which differ by up to 1 % with or without technological gaps between the elements, each side of the elements inside the lattice is adjacent to one side of the neighboring elements. Method for manufacturing the device includes obtaining a phased lattice pattern with a random arrangement of radiating elements by forming its computer model, followed by manufacturing the device according to the obtained template, choosing the shape of the surface and the shape of the lattice surface to obtain this template, as well as the number of its radiating elements, application to the resulting surface in accordance with the uniform distribution law of a random set of points, the number of which is determined on the basis of the number of lattice elements, with at least 1,000 points specified per element, all points are randomly divided into groups with respect to the number of lattice elements, a pair of groups is selected in which a pairwise replacement of points is made with the formation of disjoint regions, followed by a search of the remaining pairs of groups, the process of pairwise division of groups continues until all the groups are separated from each other to form disjoint cells, for each cell a minimal convex hull is built around all the points of the cell and forms an element of the lattice of a polygonal shape, to obtain active elements of the same area, each of the sides of the elements inside the lattice is adjacent to one of the sides of the neighboring elements.EFFECT: use of a group of inventions makes it possible to increase the efficiency of tissue destruction.11 cl, 7 dwgГруппа изобретений относится к медицинской технике, а и
