Ultrasound diagnosis apparatus with row-column addressing

An ultrasound diagnosis apparatus comprising:

• an ultrasound probe including a plurality of transducer elements arranged two-dimensionally and including a plurality of transducer element groups of a Row-Column Addressing type in which, when ultrasound transmission is to be performed, a plurality of first transducer elements arranged in a direction of one of two axes intersecting each other are connected in common to one another and in which, when ultrasound reception is to be performed, a plurality of second transducer elements arranged in a direction of the other of the two axes are connected in common to one another;
• and
• processing circuitry configured to perform a beam forming process on a plurality of reception signals output from the plurality of transducer element groups, to generate ultrasound image data on a basis of a signal obtained from the beam forming processes, and to cause a display device to display an ultrasound image based on the ultrasound image data, wherein
• each of the plurality of transducer element groups outputs, as each of the plurality of reception signals, a reception signal obtained by adding up signals output from the plurality of second transducer elements connected in common to one another,
• a plurality of sets that are each made up of the two axes and correspond to the plurality of transducer element groups of the Row-Column Addressing type are mutually different,
• with respect to the plurality of the transducer element groups, a direction in which a plurality of first transducer elements in one of the plurality of the transducer element groups connected in common to one another is arranged and a direction in which a plurality of first transducer elements in another of the plurality of the transducer element groups connected in common to one another is arranged are mutually different, and
• a direction in which a plurality of second transducer elements in one of the plurality of the transducer element groups connected in common to one another arranged and a direction in which a plurality of second transducer elements in other of the plurality of the transducer element groups connected in common to one another arranged are mutually different.
