<p><P>PROBLEM TO BE SOLVED: To enable an operator to subjectively diagnose a failure of ultrasonic transducers. <P>SOLUTION: When a verification mode is chosen by operation of an operation part 14, an MUX 40 captures an image of a phantom 27 by driving one or more of a plurality of ultrasonic transducers (UT) 32 constituting an ultrasonic transducer array (UT array) 21 without overlapping. A detection signal according to a reflected wave from the phantom 27 obtained by this is inputted to a wave detection Log compression circuit 50 without passing through a beam former (BF) 49. A digital scan converter (DSC) 51 causes a monitor 15 to align and display B-mode images corresponding to each of the UTs 32 and a number for distinguishing each UT 32. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
