Abstract

Abstract A novel apparatus for diagnosing cerebral infarction uses a neural network, wherein plural sets of data previously obtained from healthy and sick person, each including an age, measured values of coagulo-fibrinolytic molecular markers (e.g. D-dimer, TAT and PAP), an index indicative of the state of cerebral infarction (e.g. 0 for healthy persons and 1 for sick persons) are repeatedly input into a neural network to let is learn the correlation to these characteristics and, thereafter, a set of data of a person to be diagnosed, including his age, measured values of the coagulo-fibrinolytic molecular markers and the like, are input into the neural network to obtain an index indicative of his state of cerebral infarction as a degree of dangerousness of cerebral infarction. This apparatus carries out a method which is significantly higher in accuracy as compared with the prior art methods using the same data.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 145 words
Apparatus for diagnosing cerebral infarction comprising a neural network, means for supplying plural sets of learning data obtained from healthy persons and patients of cerebral infarction to the neural network to cause said neural network to learn the same, each said set including an age, a coagulo-fibrinolytic molecular marker measurement and an index indicative of cerebral infarction, and means for supplying a set of testing data obtained from a person to be tested to said neural network, the neural network being arranged to obtain an index indicative of cerebral infarction of said person to be tested as the output of said neural network, the neural network being arranged to obtain an index indicative of cerebral infarction of said person to be tested as the output of said neural network, said set of testing data including an age and a measurement of said coagulo-fibrinolytic molecular marker.
Claim 2
Dependent Claim 16 words
Apparatus as set forth in claim 1, characterized in that said coagulo-fibrinolytic molecular marker is D-dimer.
Claim 3
Dependent Claim 18 words
Apparatus as set forth in claim 1, characterized in that said coagulo-fibrinolytic molecular maker is thrombin-antithrombin III complex.
Claim 4
Dependent Claim 17 words
Apparatus as set forth in claim 1, characterized in that said coagulo-fibrinolytic molecular marker is plasmin-α₂-antiplasmin complex.
Claim 5
Dependent Claim 26 words
Apparatus as set forth in claim 1, characterized in that said learning data and said testing data further include an index indicative of sex distinction, respectively.
