Project summary

The project is devoted to development of medical equipment - a joulemetric tomograph, designed for preoperative diagnosis of tissue pathologies and for realization of tissue-saving methods during operations concerning cancer, intestinal ischemia, gangrene of extremeties, pancreatonecrosis. It is of great social and economic importance.

Existing methods of operations concerning cancer, intestinal ischemia, gangrene of extremeties, pancreatonecrosis are based on removal of considerable mass of tissue, including normal one. These methods are connected with a high level of traumatism and probability of incomplete removal of pathologic tissues.

For solution of these problems it is offered to use a new quantum joulemetric method. As a data parameter in the suggested method there is used a normalized fraction of joule (quantum). Quantitative evaluation of the state of organs and tissues is fulfilled by quanta and is valued as a work expended by an external energy source on converting the studied object from one state to another. Physically this parameter is determined by time integration of product of switching current and the potential value between electrodes.

On the basis of joulemetric data processing there is generated a tomographic image of a patient's body part. During an operation a surgeon is able to make a resection along the line of the selected level, corresponding to pision of tissue into "norm" and "pathology".

Realization of this project solves the main task of ISTC - re-orientation of research activities of specialists working in the military field to peaceful aims.
