计量诊断是一种数理统计诊断方法,有人亦称其为电子计算机辅助诊断技术。计量诊断原理是将已知的一定数量的确诊病例的症状、体征和检验、辅助检查等数据,按照一定的数学模型如(Bayes判别式、Fisher准则等),经过计算归纳为一定的数学公式或计量诊断表;当病人就诊时,即可根据病人临床表现的数据代入公式或查表,从而得出以数量大小或概 Metrology diagnosis is a mathematical statistical diagnosis method, some people also call it the computer-aided diagnosis technology. The principle of metrological diagnosis is to summarize a certain number of known symptoms, signs and tests, auxiliary examinations and other data in accordance with certain mathematical models such as (Bayes discriminant, Fisher criterion, etc.) into a certain mathematical formula or Metered diagnostic table; when the patient visits, according to the patient’s clinical performance data into the formula or look-up table, resulting in the number of size or probability
