Abstract
An object information acquiring apparatus includes: a plurality of detecting elements each receiving an acoustic waves having propagated from an object irradiated with light and outputting an electrical signal; a probe that supports the plurality of detecting elements so that a high-resolution region in which directivity axes of at least part of the plurality of detecting elements converge is formed; a processor acquiring specific information on the object using the electrical signal; and a memory storing correction data for correcting the electrical signals output by the plurality of detecting elements, and used when the processor acquires the specific information.
Claims14
An object information acquiring apparatus comprising:
- a plurality of detecting elements configured to receive an acoustic wave having propagated from an object irradiated with light and output an electrical signal respectively;
- a probe configured to support the plurality of detecting elements so that a high-resolution region in which directivity axes of at least part of the plurality of detecting elements converge is formed;
- a processor configured to acquire specific information on the object using the electrical signal;
- and
- a memory configured to store correction data for correcting the electrical signals output by the plurality of detecting elements, and used when the processor acquires the specific information, the correction data including information based on a position of each of the plurality of detecting elements and information based on sensitivity, wherein
- the processor revises the correction data on the basis of the electrical signals output by the plurality of detecting elements when a light absorber for calibration disposed at a predetermined position in relation to the probe is used as the object during calibration of the object information acquiring apparatus.
