- 摘要：
PROBLEM TO BE SOLVED: To reduce a side lobe and simplify constitution and control when two-dimensionally scanning ultrasonic beams using a two-dimensional array transducer in a three-dimensional ultrasonograph.
SOLUTION: A sub array pattern set on the two-dimensional array transducer 16 includes four sub array groups A-D. The first and third sub array groups A and C consist of a plurality of X-directional connection bodies (vertically-long pairs), while the second and fourth sub array groups B and D consist of a plurality of Y-directional connection bodies (laterally-long pairs). Each X-directional connection body Px consists of a plurality of vertically-long sub arrays aligned in the X direction and each Y-directional connection body Py consists of a plurality of laterally-long sub arrays aligned in the Y direction. Each sub array includes a rectangular shape and the plurality of sub arrays with the same shape are aligned to constitute a square connection body, thereby attaining the diversity and closeness on the sub array pattern. Each sub array group consists of the connection bodies of the same type to facilitate control on a group basis.
