Abstract

New method for investigations of a biological tissue was developed. Created method is based on images processing. Imaging of hidden objects in a scattering and absorbing medium is considered in the framework of eight-flux model for transport equation. For investigation of scattering and fluorescent signal laser-fiber spectrum-analyzer 'LESA-6' ('BioSpec,' Russia) was applied. Some experiment were carried out using CCD-camera. We present a reconstruction scheme allowing to solve the inverse problem for eight-flux approximation. The algorithm utilizes angular property of the linear scattering operator. The algorithm solves the inverse problem using set of optical images. For large number of phantoms hidden in a strongly scattering and absorbing medium we have got optical density reconstruction with satisfactory quality.
