Present Status of Research

Brief Description of Research

The goal of the project is the development of methods, devices, and software for determining the characteristics of 3D stochastic objects from the statistical characteristics of their 2D projections.

There are some tentative theoretical results (Liu and Frank, 1995; Ushakov, 1997) and applied results in the field of structural biology.

The object of the project is to solve a fundamentally new problem that involves significant upgrading of the informative potentialities of tomographic methods.

An extended concept of the object in tomographic analysis will be considered involving objects varying with time (during observation), as well as sets of similar (but different) objects, for example, sets of randomly orientated macromolecules, such that each of the projections come from a different particle.
