处理装置、超声波设备、超声波探测器及超声波诊断装置
Abstract:
本发明提供了一种处理装置、超声波设备、超声波探测器及超声波诊断装置。处理装置包括对超声波设备输出驱动信号的发送部；进行来自超声波设备的接收信号的接收处理的接收部；以及控制发送部及接收部的控制部。超声波设备具有：配置有具有第一频率的谐振特性的多个超声波元件的高频超声波元件列以及配置有具有比第一频率低的第二频率的谐振特性的多个超声波元件的低频超声波元件列。发送部在第一模式中对高频超声波元件列输出正弦波的驱动信号，在第二模式中对低频超声波元件列输出矩形波的驱动信号。
Abstract(English):

A processing device that performs a process of transmitting and receiving an ultrasonic wave includes an ultrasonic device, a transmitter, a receiver, and a controller. The transmitter is configured to output a driving signal to the ultrasonic device. The ultrasonic device includes a high-frequency ultrasonic element line and a low-frequency ultrasonic element line. The high-frequency ultrasonic element line is configured to arrange a plurality of ultrasonic elements having a resonance characteristic of a first frequency. The low-frequency ultrasonic element line is configured to arrange a plurality of ultrasonic elements having a resonance characteristic of a second frequency. The transmitter is configured to output the driving signal of a sine wave to the high-frequency ultrasonic element line in a first mode. The transmitter is configured to output the driving signal of a square wave to the low-frequency ultrasonic element line in a second mode.
