| 20110074244 | Ultrasonic probe - An ultrasonic probe has transmitting ultrasonic transducers and receiving ultrasonic transducers. The transmitting ultrasonic transducer is composed of a multilayer piezoelectric element, and the receiving ultrasonic transducer is composed of a single-layer piezoelectric element. The transmitting and receiving ultrasonic transducers are alternately arranged in an azimuth direction to form a piezoelectric element line. The single transmitting ultrasonic transducer and the single receiving ultrasonic transducer that adjoin to each other compose a single channel to transmit ultrasonic waves and receive echoes. The transmitting ultrasonic transducer is connected to a transmission circuit board on which a pulser is implemented, and the receiving ultrasonic transducer is connected to a reception circuit board on which an amplifier is implemented. The receiving ultrasonic transducer is directly connected to the amplifier without passing through a capacitance transmission line. | 03-31-2011 |
| 20110077520 | Ultrasonic diagnostic apparatus and ultrasonic diagnostic method - An ultrasonic probe has a plurality of ultrasonic transducers (UTs). Each UT transmits ultrasonic waves and receives echo waves. In a B/A coefficient acquisition mode, every time a transmission of the ultrasonic waves and reception of echo waves takes place, ultrasonic waves for heating are transmitted to heat an object of interest. An HI processor calculates a non-linear B/A coefficient based on a harmonic component of a detection signal from the UT. The HI processor acquires information of changes in the B/A coefficient while the object of interest is heated with the ultrasonic waves for heating. A DSC displays the information of the B/A coefficient together with an ultrasonic image on a monitor. | 03-31-2011 |
