<P>PROBLEM TO BE SOLVED: To provide a technique for preventing an imaging range from narrowing than a machine scanning range in an ultrasonic acquiring apparatus for performing image configuration by a synthetic aperture. <P>SOLUTION: A subject information acquiring apparatus includes: a probe for electrically scanning a subject in a first direction and mechanically scanning in a second direction intersecting with the first direction; a first phasing and addition means for phasing and adding a received signal; a memory for storing a first phasing and addition signals for each tomographic plane in the second direction; a means for selecting signals corresponding to M tomographic planes from among the stored signals; a second phasing and addition means for phasing and adding the selected signals in the second direction; and a means for acquiring image data in the subject from the second phasing and addition signals. The second phasing and addition means, which is in accordance with mechanically scanning of the probe, includes a first case for fixing M signals and changing a delay pattern and a second case for changing a lot of the M signals and fixing the delay pattern. <P>COPYRIGHT: (C)2012,JPO&INPIT |
