Capacitive micromachined ultrasonic transducer (cMUT) device and in-body-cavity diagnostic ultrasound system |
| 摘要 |
<p>A capacitive micromachined ultrasonic transducer (cMUT) device (40), comprises: a cMUT (42) obtained by processing a silicon substrate by using a silicon micromachining technique; and an oscillator circuit (41) having the cMUT (42) as a capacitor, and outputting a frequency modulation signal by modulating a frequency of an oscillation signal to be output on the basis of a change of capacitance of the cMUT (42).
