[Claims for Utility Model Registration] 1. An ultrasonic imaging device that transmits or receives ultrasonic signals using an array type transducer consisting of a large number of elements arranged at equal intervals, which In a device that forms a transmitting or receiving beam by giving a common delay time to the signals of one or more elements adjacent to each other, the number m (≧1) of elements belonging to each element group giving a common delay time, An ultrasonic imaging device characterized by monotonically and non-increasingly changing elements from a group of elements located at the foot of a perpendicular line drawn from a beam focus to the array to a group of elements around the aperture. 2 Utility Model Registration In the device according to claim 1, all the elements in the used aperture are divided into segments consisting of n elements adjacent to each other, and m from each segment are divided into segments that provide the common delay time. Select (1≦m≦n) mutually adjacent elements,
An ultrasonic imaging device characterized in that each element group is one element group. 3 Utility Model Registration In the device according to claim 2, for k (≧1) element groups centered on the central element group, the m is set as □m=n, and the other elements An ultrasonic imaging apparatus characterized in that for a group, m=1.
