Method and device for examination by means of ultrasonic beams

摘要: A method of and a device for ultrasonic examination an object by means row N electroacoustic transducers. Each time group M transducers (M≧N) thereof is selected switching member. These are first included in transmission networks, signals then being applied to the converters; subsequently, they receive display device. The and/or multiplied weighting factors between 0 1. sum during may deviate from that reception. During reception, at least two different combinations used, each same. scanning line density can thus be substantially increased.
