Claim of US Patent No. 10,105,061

1. A subject information obtaining apparatus comprising:a receiver having a plurality of conversion elements which receive acoustic waves and output reception signals and a supporting member that supports the plurality of conversion elements such that directional axes of the plurality of conversion elements gather;
a movement mechanism configured to move the receiver; and
a controller configured to control a movement of the movement mechanism to move the receiver along a scanning trajectory by moving the receiver relative to an examined portion of the subject, a center position of the scanning trajectory being a center of gravity of a region formed by tracing an outer periphery of the scanning trajectory,
wherein the controller controls the movement mechanism so that in a case in which the examined portion lies in the left side of the body, the center position of the scanning trajectory of the receiver is offset from the center position of the scanning trajectory of the receiver from where the center position of the scanning trajectory of the receiver would be in a case the examined portion lies in the right side of the body.
