An ultrasound transducer comprising an array of electro-acoustic micro-cells (102, 102′, 103, 103′, 104), a first (302, 303, 304) and a second (402, 403, 404) group of transducer elements arranged substantially along two directions (x, y), each element being defined by a group of micro-cells of the array (102, 102′, 103, 103′, 104), at least part of the micro-cells (102, 103, 104) of each group being electrically interconnected by a first connection pattern having shape with main orientation along one of the two directions (x, y) and substantially extending along the entire element, characterized in that each group of micro-cells (102, 102′, 103, 103′, 104) defining each element (302, 303, 304) comprises micro-cells (102′, 103′, 104) interconnected by further connection pattern or patterns having shape with main orientation along the other of the two directions (y, x), such further connection pattern or patterns being electrically isolated from the first connection pattern.
