摘要:
An ultrasonic probe apparatus which applies a RF pulse signal with a DC bias signal superimposed thereon to c-MUTs (1-1 to 1-n) and transmits/receives an ultrasound wave is configured such that a transmission control system includes bias regulators (6-1 to 6-m) which regulate the voltage value of the DC bias signal, a reception control system has a plurality of different frequency band pass filtering characteristics including at least those for a low pass and high pass and a frequency band pass filtering processing section 10 which can select at least one frequency band pass filtering characteristic from those frequency band pass filtering characteristics. The apparatus controls voltage settings of the bias regulators (6-1 to 6-m) in conjunction with the selection of frequency band pass filtering characteristics of the frequency band pass filtering processing section 10.
