Abstract
An apparatus for the examination of an object by ultrasonic echography, includes an array of n ultrasonic transducers which is associated with a stage for the emission of signals for scanning the object and with a stage for receiving and processing echographic signals retumed to the transducers, by the obstacles encountered in the object scanned. The emission stage is configured for the focusing of m simultaneously emitted ultrasonic beams, by virute of n emission modules, each of which, for example, the i.sup.th emission module, itself contains m signal generators (201a.sub.1, . . . , 201m.sub.1) which are connected in parallel (or a single signal generator followed by m parallel-connected delay circuits), a stage (202i) for combining the m signals thus generated, and an amplifier (203i) for applying the amplified combined signal to the transducer (10i) corresponding to the relevant emission module.
