ULTRASONIC IMAGING APPARATUS

摘要

PURPOSE: An ultrasound imaging apparatus is provided to reduce the electrical energy consumption by eliminating the consumption of the stable current. CONSTITUTION: A pulsator(33) comprises multiple first push-pull circuits having the output unit which is coupled to the output line(1) and output line combined with the piezoelectric transducer(11). The power supply supplies voltage having different level to first push-pull circuits. The first push-pull circuits comprises the first rectifier element preventing the reverse current applied to the first complementary type transistor. The pulsator comprises the second push-pull circuit having the output unit. The same power supply voltage as the first push-pull circuit is applied to the second push-pull circuit.
