STUDY OF DIFFUSIVE MEDIA WITH LOW SCATTERING HETEROGENEITIES
Biological tissues have the particularity of allowing light between 600 and 900 nm, within a range called optical window, to penetrate them a few centimeters. This characteristic arouses interest in the near infrared light for its use as a diagnosis tool, with the characteristic of being non-invasiv...

| description | Biological tissues have the particularity of allowing light between 600 and 900 nm, within a range called optical window, to penetrate them a few centimeters. This characteristic arouses interest in the near infrared light for its use as a diagnosis tool, with the characteristic of being non-invasive, its application in breast diagnosis is of particular interest for this study. These tissues do not allow the propagation of light in this spectral range in a rectilinear manner, but rather appear as diffusive, thus deteriorating the spatial resolution of the images that can be obtained from them. In this way, it is necessary to develop experimental techniques and specific data analysis strategies in order to obtain optical information from them. Breast tissue can suffer different types of lesions, such as tumors or cysts. This work presents the study of phantoms, which reproduce their optical properties with inclusions that represent tumors and / or cysts, analyzing the influence of the latter, which optical characteristics are non-diffusive, on optical images and the transport of light in these media. The main objective of this work is focused on the 3D localization and optical characterization of translucent heterogeneities in turbid media |
