頭部CTにおける正常・異常の数値判別

An Attempt to Numerical Diagnosis by Computed Tomography

Ⅰ．はじめに

　著者らは，頭部CTによる自動診断を目的として，いくつかの数値的診断法を試みてきた．今回，許容線形判別分析を用い，正常・異常の数値診断を試みたところ，良好な結果が得られたので報告する．

In the previous report, the authors described a method obtaining numerical values of 'standard deviation (SD) and deviation coefficient (DC) from printed out data of a brain CT slice picking up the basal ganglia. In the report, using these values, a possibility of numerical discrimination between normal and abnormal was also discussed.

In the present investigation, it was attempted to apply admissible linear discriminant analysis to numerical diagnosis using SD value and DC value.
