1. A medical apparatus for acquiring information indicative of an internal state of a region being examined of an object based on a modulated component of light caused by interaction with ultrasound waves in the region, the apparatus comprising:

  • light radiating means having a light radiating member for radiating the light toward the region of the object;

    light detecting means having a light detecting member for detecting light that has been transmitted through the region of the object, the transmitted light being the light radiated from the light radiating member;

    support means for supporting both the light radiating member and the light detecting member so as to be opposed to each other with the region located between the light radiating and detecting members; and

    ultrasound emitting means having an ultrasound emitting member for emitting the ultrasound waves toward the region of object from a direction different from a radiating direction of the light radiated from the light radiating member, the emitted ultrasound waves modulating the radiated light.
