Near infrared imaging is a medical imaging modality in which red and near infrared light is used to probe biological tissues. Images are obtained by mapping the absorption coefficient of the tissue. Light, however, is strongly scattered by tissues, and scattering of light makes the image reconstruction very difficult. Realization of clinically viable near infrared imaging techniques depends on the development of reliable and fast methods of obtaining inverse solutions of the radiative transfer equation. In this paper we describe a technique for obtaining images from a limited number of continuous wave scattering measurements using homogeneous and inhomogeneous solid cylindrical phantoms. We propose the use of the zooming method as a way to improve the resolution of the images which are obtained by a quasi-Newton's method for the inversion procedure.
