Title:
IMAGE-GENERATION DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2013/128921
Kind Code:
A1
Abstract:
[Problem] To apply a sound-speed distribution generated on the basis of a detection signal of an acoustic wave differing from a generation subject, and generate an image, using a device for detecting both a photoacoustic wave and a reflected acoustic wave. [Solution] A probe (11) detects a reflected acoustic signal in a transmitted acoustic wave, and a photoacoustic signal produced inside the body of a subject by photoirradiating the subject. A sound-speed-distribution generation means (27) generates a sound-speed distribution of the interior of the body of the subject on the basis of the reflected acoustic signal. A photoacoustic-image generation means (25) generates a photoacoustic image on the basis of the photoacoustic signal and the sound-speed distribution.
