[The determination of the sensitivity and specificity of the interpretation rules parameters in a study of the medical equipment testing].
The interpretation systems of medical instruments are traditionally assessed by their sensitivity and specificity in definitions of the binary classification scheme. However, should the system's conclusions on the presence of a pathology be extended by a multitude of degrees of its pronouncement, such scheme is unacceptable. A three-digital classification scheme with isolated degrees of pronounced and weak pathology signs reflects, firstly, an understanding of the interpretation error value between these two degrees and, secondly, the harmlessness of errors inside each degree. The discussed logical and probabilistic models of constructing the quality parameters ensure the continuity in respect to the indices of the binary classification scheme, however, it can be stated that the probabilistic parameters are more preferable.
