    摘要： The ultrasonic diagnosis apparatus according to the embodiments transmits ultrasonic waves to a subject, generates an ultrasound image based on the signals received from the subject, and comprises sub arrays, a main array, an aperture diameter setting part, and a delay pattern setting part. The sub arrays consist of a plurality of ultrasound transducers that are two-dimensionally disposed, and have a fixed delay pattern during a single receiving period. The main array consists of sub arrays. The aperture diameter setting part sets the aperture diameter of the main array. The delay pattern setting part changes the delay pattern for each of the sub arrays depending on the aperture diameter.

    摘要： An ultrasound probe and an ultrasound diagnosis apparatus are provided that are capable of reducing the frequency with which false images are generated in an ultrasound diagnostic image. An ultrasound probe of an embodiment comprises a transducer element unit in which multiple groups of transducer elements are arranged, and a selection means. Each of the multiple groups of transducer elements has a first to nth subgroups of transducer elements. Emitting surfaces of the transducer elements included in the first to the nth subgroups of transducer elements are arranged such that they face different directions for each subgroups of transducer elements. The selection means is provided to selectively activate a specific subgroup of transducer elements from among the first to the nth subgroups of transducer elements, based on an external activation signal.
