DEVICE FOR PHOTO-ACOUSTIC VISUALIZATION, METHOD OF PHOTO-ACOUSTIC VISUALIZATION AND A PROGRAM FOR IMPLEMENTING A METHOD OF PHOTO-ACOUSTIC VISUALIZATION

摘要

1. A device for obtaining information about a subject, comprising: an acoustic conversion unit configured to receive an acoustic wave generated by irradiating a subject with light, and convert the acoustic wave into an electrical signal; a processing unit configured to obtain a distribution of optical properties within a subject based on an electrical signal, the shape of the subject, and the distribution of light intensity for irradiating the subject. 2. The device for obtaining information about a subject according to claim 1, wherein the processing unit is configured to obtain a distribution of light intensity or a distribution of illumination from light incident on the surface of the subject, based on the shape of the subject and the distribution of light intensity for irradiating the subject, and obtain a distribution of optical properties within the subject based on an electrical signal, the shape of the subject and the distribution of light intensity or the distribution of illumination from light incident on the surface of the subject. 3. The device for obtaining information about a subject according to claim 2, wherein the processing unit is configured to obtain a distribution of light intensity inside the subject based on the shape of the subject and the distribution of light intensity or light distribution from the light incident on the subject’s surface, and obtain a distribution of optical properties within the subject based electrical signal and light intensity distribution within the subject. 4. The device for obtaining information about the subject according to claim 1, further comprising a measuring unit configured to measure the shape of the subject;
