Abstract:
Method of recording mechanical damped natural oscillations of soft biological tissues of a tissue-bearing subject via exerting on the soft biological tissue an external mechanical impact at a testing end and subsequently recording the mechanical response of the biological tissue as a graph of damped natural oscillations of the tissue, wherein:before exerting the external mechanical impact on the biological tissue at the testing end, an inflexible plane means is fastened onto the biological tissue in order to mark the tissue area under investigation and to facilitate the connection of the testing end with the tissue in a manner that prevents the testing end from harming the tissue,thereafter the testing end is inflexibly connected to the inflexible plane means over a duration sufficient for influencing the tissue mechanically and for recording the mechanical response of the biological tissue, andthereafter an external mechanical impact is applied to the tissue under investigation over a duration of some milliseconds, ending with rapid cessation of the impact, whereby the following are avoided:harm to the biological tissue;changes in metabolic processes of the tissue; andneurological reactions of the tissue under investigation.
