METHOD AND APPARATUS FOR ULTRASOUND TESTING USING A MATRIX PHASED ARRAY PROBE

摘要

In order to reduce the number of electronic channels required for ultrasound testing of an object under test using a matrix phased array probe (5) which comprises a two-dimensional arrangement of a number of ultrasound sensors/individual elements (6), the invention proposes combining and electrically interconnecting in each case a plurality of individual elements (6) of the matrix array into groups (7) in a suitable manner, for example in lines or in polygons (9), by means of a switching unit and in each case jointly actuating the individual elements (6) of one group (7).
