Lung cancer is one of the most widely spread in structure of human oncological diseases. It has continuous hidden course and clinically presented only when disease symptoms are quite apparent and only surgical treatment is possible.

    Due to this fact improvement of lung cancer diagnostics should be done in two following directions: search of methods for early tumor process detection at pre-clinical development stage and optimization and shortening of pre-operative tumor diagnostics period. Main diagnostic method is roentgenology of chest together with tomography. Roentgenological semiotics of lung cancer depends of form of primary tumor and composed of shadow pattern of tumor itself, caused by tumor airway conductance disorders and secondary metastatic changes in lungs, mediastinum and pleura. Modern computer technologies (computed tomography and its modifications, magnetic resonance imaging) made possible to extend significantly potentials of pathological changes in lungs visualization, but in practice they remain rather expensive and not readily available. At this background new method of hardware diagnostics – NLS-examination of chest remains unclaimed; it is considered to have low information value due the fact that majority of experts are unaware of all potentials of modern NLS-diagnostic devices - Metatron Hunter 4025.
