We used synchrotron spectromicroscopy to study the microscopic distribution of baron in rat brain tumour and healthy tissue in the field of baron neutron capture therapy (BNCT). The success of this experimental cancer therapy depends on the preferential up ...
We develop a fully vectorial formalism for the investigation of electromagnetic scattering in polarizable backgrounds, i.e., where the scatterers are not in vacuum but situated in a medium with a dielectric permittivity different from unity. Our approach i ...
The spatially resolved reflectance of turbid media is studied at short source–detector separations (approximately one transport mean free path) with Monte Carlo simulations. For such distances we found that the first and second moments of the phase functio ...
A non-invasive probe has been devised and clinically used to perform in vivo measurements of the optical properties of the esophageal wall and oral cavity. The absorption and reduced scattering coefficients are determined from the observation of the spatia ...
Local and superficial near-infrared (NIR) optical-property characterization of turbid biological tissues can be achieved by measurement of spatially resolved diffuse reflectance at small source–detector separations (
The design and characterization of optical phantoms which have the same absorption and scattering characteristics as biological tissues in a broad spectral window (between 400 and 650 nm) are presented. These low cost phantoms use agarose dissolved in wate ...
A non-invasive method to measure the optical properties of a turbid medium such as biological tissue is described. To determine the absorption and reduced scattering coefficient, the sample is illuminated with spatially intensity modulated light and the ba ...
