There is provided a system for supporting the assessment as to which disease group the subject to be examined falls in or what position in the whole disease group the subject is in. This support system comprises the data storage part which stores feature values of optical bio-measurement data of many subjects including patients in multiple disease groups, the analysis part which extracts plural kinds of feature values from the optical bio-measurement data and the display part which displays the results of analysis in the analysis part associated with the dictionary data, wherein the display part produces a scatter diagram on which features values of the dictionary data are plotted, with one of the two feature values being plotted along the axis of abscissa and the other along the axis of ordinate, and displays the positions of the subject to be assessed on the scatter diagram superimposed on the scatter diagram. With this scatter diagram, the relationship between the features of the subject and the feature of the disease group can be known in one glance.

Disease diagnosis support system

An apparatus which can objectively assess and display to what extent and to which disease the subject belongs based on the signals of changes in hemoglobin amount measured by the optical measurement apparatus is provided. The disease assessment apparatus comprises the feature extraction unitfor extracting features of the hemoglobin waveform, the feature analysis unitand the storage unitfor storing features by each disease as database. The disease is assessed by extracting various kinds of feature amounts from the hemoglobin signals of the subject measured by the optical measurement apparatus in the feature extraction unitand by applying multivariate analysis of similarities between feature amounts extracted and feature amounts stored by disease in the storage unitResults of assessment are shown as scores expressing similarity with each disease group in a bar graph.
