Abstract
An ultrasonic diagnosing apparatus includes: a transducer arraycomposed of arrayed transducer elements Tto Tfor transmitting ultrasound; driving circuits DA to DA each provided for transmission channels for driving each of the transducer elements; a transmission trigger generatorfor generating a trigger pulse for controlling each of the driving circuits; a parallel reception beam formerfor processing reception signals from the transducer elements; a signal processorfor processing an output signal of the parallel reception beam former; and a control unitfor controlling the transmission trigger generator, the parallel reception beam former and the signal processor. The transmission trigger generator controls the width of the trigger pulse independently for each of the transmission channels to cause the driving circuit to output a driving pulse approximating a predetermined weighting value assigned to an output amplitude of each of the transmission channels in a transmission aperture of the transducer array. A circuit for forming a trapezoidal transmission beam for increasing a data acquisition rate by using parallel reception beams can be configured at low cost by using pulse amplifiers.
