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.
