PHOTOACOUSTIC MEASUREMENT APPARATUS AND PROBE FOR PHOTOACOUSTIC MEASUREMENT APPARATUS

摘要

The light irradiation range of a probe for a photoacoustic measurement apparatus is increased. The probe for a photoacoustic measurement apparatus includes a light transmission unit that irradiates a subject with light, and a photoacoustic wave detector 52 that detects a photoacoustic wave generated from the subject. The light transmission unit includes light propagation part 51 for propagating light, and a light transmission member 55. Further, the light transmission member 55 includes an inner peripheral surface 55a that is formed in the shape of a curved concave surface and an outer peripheral surface 55b that has a radius of curvature larger than the radius of curvature of the inner peripheral surface 55a and is formed in the shape of a curved convex surface. The outer peripheral surface 55b is disposed so that the light L emitted from the light propagation part 51 is incident on the inner peripheral surface 55a.

1. A probe for a photoacoustic measurement apparatus comprising:
a light transmission unit that irradiates a subject with light; and a photoacoustic wave detector that detects a photoacoustic wave generated from a portion of the subject irradiated with light, wherein the light transmission unit includes
a light propagation part for propagating light emitted from a light source, anda light transmission member that includes an inner peripheral surface formed in the shape of a curved concave surface and an outer peripheral surface having a radius of curvature larger than the radius of curvature of the inner peripheral surface and formed in the shape of a curved convex surface and is disposed so that light emitted from the light propagation part is incident on the inner peripheral surface.
