ABSTRACT:
In an ultrasound diagnosis apparatus, a plurality of sub arrays are defined on a 2D array transducer. The sub array shape pattern of each sub array is adaptively changed in accordance with the beam scanning direction. Each sub array is composed of a plurality of groups, each of which is composed of a plurality of transducer elements. With the change of sub array shape pattern in accordance with a beam scanning direction, the group shape pattern of each group also changes. The sub array shape changes for each sub array, and a variable region is determined by the largest outer edge of the shape changed. The variable regions partially overlap with each other among a plurality of sub arrays. On a 2D array transducer, a plurality of sub arrays are always closely coupled with each other even when each sub array shape is changed.
