| 摘要 |
The present invention relates to a photo-acoustic tomography that can acquire a functional image for an inner part of a living body through generation of a local ultrasonic wave generated by energy that is introduced from a laser light source, and to a photo-acoustic tomography using a semiconductor laser and an optical fiber power amplifying device in order to increase resolution and an image acquisition time of an image, a photo-acoustic tomography that can acquire a high-sensitive image even in a place where a penetration depth is large through energy modulation, and a high-sensitive high-speed photo-acoustic tomography that can acquire a high-speed image by placing an array-type laser light source.
