Title:
3D ACOUSTIC IMAGING DEVICE AND 3D ACOUSTIC IMAGING METHOD
Document Type and Number:
WIPO Patent Application WO/2007/088709
Kind Code:
A1
Abstract:
A 3D acoustic imaging device includes alight source (10) for generating a near infrared
pulse, means for collecting the pulse light and applying it to an examinee (15),
a laser scan unit (11) for scanning the focal position of the pulse light, and an
acoustic transducer (18) for detecting an acoustic wave generated from the examinee
(15) by multi-photon absorption of the pulse light. 3D data showing the material
distribution in the examinee (15) is acquired according to the intensity information
and the generation position information on the acoustic wave and a tomogram at
an arbitrary plane is displayed on a display unit (23). Thus, by using the non-linear
optical effect of the near infrared pulse light, it is possible to locally generate
an acoustic wave from the focal position in the examinee (15) and observe a deep
region of the examinee (15) with a high resolution. Moreover, by using the light
of a near infrared region as excitation light, it is possible to prevent attenuation
of the excitation light in a biological body and increase the penetration depth.
