Acoustic-wave measuring apparatus and method

摘要

An acoustic-wave measuring apparatus includes a holding unit configured to hold a subject and an irradiation unit configured to irradiate the subject with light. An acoustic-wave detecting unit detects acoustic waves generated in the subject due to irradiation with the light; an image pickup unit acquires an image of the subject; and a measurement position on the image acquired by the image pickup unit is designated. A coordinate transforming unit transforms the coordinates of the measurement position on the image to coordinates of a corresponding position on the holding unit; and a position control unit moves at least one of the irradiation unit and the acoustic-wave detecting unit to the corresponding position on the holding unit.

1. An acoustic-wave measuring apparatus comprising:
a holding unit configured to hold a subject; an irradiation unit configured to irradiate the subject with light; an acoustic-wave detecting unit configured to receive acoustic waves generated within the subject due to irradiation with the light irradiated from the irradiation unit, the acoustic-wave detecting unit being disposed at a side of the holding unit opposite to the subject; an image pickup unit configured to acquire, through the holding unit, an image of a shape of the subject held by the holding unit; a coordinate transforming unit configured to transform coordinates of a measurement position designated by an observer, on the image acquired by the image pickup unit to coordinates on the holding unit; and a position control unit configured to move at least one of the irradiation unit and the acoustic-wave detecting unit on the holding unit based on information output from the coordinate transforming unit.
