Phantom having similar optical characteristics to living tissues.

摘要

A phantom having similar light scattering characteristics to living tissues of interest is obtained by suspending in a selected medium (2) a mixture of particles (3) of different-valued radius rk at respective values of concentration Ck which are determined on the basis of the following matrix equation: <MATH> where Pmeas( theta i) is a scattering intensity of light with the living tissues at a scattering angle theta i and P( theta i,rk) is a scattering intensity with the particles having the radius rk at the scattering angle theta i.
