Title:
IMAGE INFORMATION ACQUIRING APPARATUS, IMAGE INFORMATION ACQUIRING METHOD AND IMAGE INFORMATION ACQUIRING PROGRAM
Document Type and Number:
Japanese Patent JP2012024227
Kind Code:
A
Abstract:

To provide technique for obtaining reconstructed image data which reduces an artifact when acoustic waves are detected by an acoustic wave detector disposed on a flat plate.

An image information acquiring apparatus includes: an acoustic wave detection unit having a plurality of elements disposed on a reception surface for detecting acoustic waves generated by a subject corresponding to a reconstruction area; an acoustic signal generation unit for generating acoustic signals which are used in image reconstruction from the acoustic waves detected by the acoustic wave detection unit; an element selection unit for selecting elements which are used in image reconstruction; and a reconstruction unit for performing image reconstruction of a point of interest using acoustic signals on the basis of the acoustic waves detected by the selected elements. The image information acquiring apparatus is characterized in that another selected element is placed on a symmetrical position with respect to a point at which the receiving surface is intersected by a perpendicular line drawn from the point of interest to the reception surface by each selected element.
