Abstract

PURPOSE:To easily improve transmitting efficiency and receiving sensitivity corresponding to the characteristic of a functional element part, by constituting a series resonance circuit of the circuit of a cable-containing ultrasonic probe system and the inductor on the side of the ultrasonic diagnostic apparatus main body of the cable or in said apparatus main body. CONSTITUTION:An inductor Lo is arranged on the side of the ultrasonic diagnostic apparatus main body of a cable or in said main body. At the time of transmission, series resonance is generated at desired frequency in an ultrasonic probe system and the impedance of the circuit of the ultrasonic probe system falls. Therefore, the efficiency to a drive voltage signal becomes well. Since impedance becomes large at high frequency by resonance frequency, a high frequency component is removed. At a receiving time, a signal is propagated by the circuit constitution having the input resistor R of a receiving amplifier as load in the ultrasonic diagnostic apparatus main body 4. Since series resonance is also generated at this time, the voltage of a receiving signal applied to the input resistor R becomes max. Therefore, receiving sensitivity is improved.
