ULTRASONIC PROBE AND ULTRASONOGRAPHIC DEVICE |
摘要 |
<p>A variance in transmitting/receiving sensitivity between multiple vibrational elements or transducers included in an ultrasonic probe is corrected. An ultrasonic probe in accordance with the present invention has multiple transducers, each of which includes multiple vibrational elements that each transmit or receive ultrasonic waves by converting ultrasonic waves and an electric signal into each other with a bias voltage applied thereto, set in array. The ultrasonic prove includes a transmitting/receiving sensitivity correction means that independently adjusts the bias voltage to be applied to at least two vibrational elements among the multiple vibrational elements so as to correct a variance in transmitting/receiving sensitivity between the at least two vibrational elements.</p> |
