<P>PROBLEM TO BE SOLVED: To provide an ultrasonograph which enables an oscillator array having an appropriate frequency band to be replaced according to diagnostic object and nonetheless is made compact and has improved operability. <P>SOLUTION: An ultrasound probe 1 has a middle unit 4 that is wirelessly connected to a back unit 2, and a front unit 3 that is connected to the middle unit 4 detachably via a connector 5, On the front unit 3, there are loaded an oscillator array 6 that has a specific frequency band, a preamp 8 that has a frequency band corresponding to the frequency band of the oscillator array 6, and a transmission driving unit 9 that outputs the drive voltage corresponding to the drive voltage for the oscillator array 6. The front unit 3, middle unit 4 and back unit 2 respectively have a dedicated CPU 10, CPU 15 and CPU 20 which control respective parts within respective unit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
