Document Type and Number:
Japanese Patent JP7258352
Kind Code:
B2
Abstract:
To execute estimation of an arrangement of a plurality of elements and generation of a picked-up image by using the same data.SOLUTION: An ultrasonic image pickup apparatus is equipped with a probe in which a plurality of elements capable of transmitting and receiving an ultrasonic signal are arranged in a line on a pedestal formed of a deformable plate-like material. The shape of the pedestal is estimated by adjusting an assumptive shape so that a shape index based on the brightness of each pixel of a temporarily picked up image constituted on the basis of the ultrasonic signal received by the plurality of elements in the assumptive shape, which is an index becoming smaller as a difference between the assumptive shape assumed as a shape of the pedestal and an actual shape of the pedestal becomes smaller, becomes small.SELECTED DRAWING: Figure 2
