    • An ultrasound diagnostic apparatus is provided which includes an ultrasound probe performing ultrasound transmission and reception in different directions and a diagnostic apparatus body combining images different in the direction of transmission and reception to produce an ultrasound image. At least one of ultrasound images to be combined is changed depending on the set region of interest (ROI) to an image of the depth corresponding to the ROI. When an acoustic coupler is attached, the depth of at least one of ultrasound images to be combined is increased. The ultrasound diagnostic apparatus is capable of improving the image quality of the ROI and obtaining efficient high-definition ultrasound images reaching a predetermined depth when the acoustic coupler is attached.
    • 提供了一种超声波诊断装置,其包括在不同方向上执行超声波发送和接收的超声波探头和组合发送和接收方向不同的图像的诊断装置主体,以产生超声波图像。 要组合的超声图像中的至少一个根据感兴趣的设置区域(ROI)改变为与ROI相对应的深度的图像。 当附接声学耦合器时,要组合的超声图像中的至少一个的深度增加。 超声波诊断装置能够提高ROI的图像质量,并且当附接声学耦合器时获得达到预定深度的有效的高分辨率超声图像。
