<p>#CMT# #/CMT# The imaging device has a coupling device including a housing receiving a collection optical fiber (12). An end of the fiber or the housing's bottom receiving the fiber is located at a distance (h) from a bearing surface (22) of a mass (30) of the coupling device, where the distance is shorter than another distance (H) from the bearing surface at which an end of an excitation optical fiber (10) or the housing bottom receiving the excitation optical fiber is located. The mass of the coupling device is made of a diffusing material at a wavelength guided by one of the optical fibers. #CMT# : #/CMT# An independent claim is also included for an optical tomography type examination method for examining a part of a medium. #CMT#USE : #/CMT# Diffuse optical imaging device for in-vivo and ex-vivo fluorescence type imaging a part of a medium i.e. human body, so as to detect tissues e.g. cancerous tumors, in the medium. Uses include but are not limited to breast, prostate, brain, testicles, arms, carotid and thyroid tissue of the medium. #CMT#ADVANTAGE : #/CMT# The impact of the incident beam on the medium is distributed over a wider surface if the fiber is used alone without the coupling device, thus minimizing damages to the medium to be examined. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a diffused optical imaging device with a hemispherical diffusion matrix. h, H : Distances 10 : Excitation optical fiber 12 : Collection optical fiber 22 : Bearing surface 30 : Mass.</p> |
