本发明提供超声波诊断装置以及超声波图像生成方法。一种超声波诊断装置，包括超声波探头、发送部、接收部、延迟量生成部、以及延迟处理部。所述延迟量生成部具有发送时间生成部以及接收时间生成部。当从发送基准点到观测点为止的距离大于从发送基准点到焦点为止的距离的情况下，发送时间生成部基于将所发送的超声波从发送基准点到达焦点的时间与从焦点到达观测点的时间相加后的时间，生成发送时间，当从发送基准点到观测点为止的距离小于从发送基准点到焦点为止的距离的情况下，发送时间生成部基于在所发送的超声波从发送基准点到达焦点的时间中减去从焦点到达观测点的时间所得到的时间，生成发送时间。 An ultrasound signal processing device: performing events involving transmitting ultrasound towards a subject; receiving ultrasound reflection from the subject in response to each event; and generating a frame signal from sub-frame signals generated based on the ultrasound reflection. The device, in each event, causes a transmission aperture to transmit ultrasound focusing in the subject. A transmission aperture for one event differs in position, in a transducer element array direction, from a transmission aperture for a previous event by a shift amount of at least one transducer element width. The device, for each event, sets a target area (Bx) which includes a position (F) where transmitted ultrasound focuses and whose width (W f )
