First Claim
Patent Images
1. A biological information processing apparatus comprising:
- a light source which emits a light to a living body;
an acoustic wave detector that detects an acoustic wave which a light absorber in the living body generates when the light absorber absorbs the light, and that converts the acoustic wave to an electric signal; and
a signal processing unit that obtains information in the living body from the electric signal and a light quantity distribution in the living body determined based on a shape of the living body.
