First Claim
1. A measuring system comprising:
- an acoustic wave receiver for receiving acoustic waves which are generated by irradiating light to a specimen, and for converting the received acoustic waves into an electrical signal; and
an image forming apparatus for producing image data by using the electrical signal,wherein the acoustic wave receiver receives direct waves and reflected waves in acoustic waves generated from a detection target inside the specimen and coverts the direct waves and the reflected waves into respective electric signals, the direct waves directly reach the acoustic wave receiver, and the reflected waves are reflected by an acoustic wave reflecting surface formed by an interface between the specimen and a medium adjacent to the specimen,the image forming apparatus includes a central processing unit (CPU) comprising;
a data producing unit for producing image data by converting the electrical signal converted from the direct waves and the electrical signal converted from the reflected waves to voxel data or pixel data;
a determining unit for determining whether, as viewed on the image data, a position of the voxel data or the pixel data converted from the direct waves and a position of the voxel data or the pixel data converted from the reflected waves are symmetrical with respect to the acoustic wave reflecting surface; and
a processing unit for executing a reduction process for images of the voxel data or the pixel data, which are determined to be not symmetrical by the determining unit.

Abstract
A measuring system for receiving acoustic waves and producing image data includes an acoustic wave receiver that detects acoustic waves which are generated by irradiating a specimen with pulsed light. The acoustic wave receiver converts the detected acoustic waves into an electric signal, and an image forming apparatus generates image data by using the electric signal. An artifact attributable to a band of an acoustic wave receiver is distinguished and reduced based on the positional relationship among respective voxel data representing an actual image and a reflected image of a light absorber located within the specimen and related artifacts, as viewed on the image data, by utilizing an acoustic wave reflecting surface on which the specimen is disposed.
