Abstract

Reception beamforming is executed using delay times that complexly vary in accordance with differences between transmission conditions. An irradiation areaof a transmission beam is calculated, and the lengths of segments, using which delay times are calculated, are set in accordance with the positional relationships between the calculated irradiation areaand reception scanning lines. For example, the reception scanning linesare divided into areas A to C, and the lengths of segmentsb in the outer area B located outside of the irradiation areaare set shorter than the lengths of segmentsa andc in the inner areas A and C.
