摘要： 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 unit 15 for extracting features of the hemoglobin waveform, the feature analysis unit 16 and the storage unit 12 for 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 unit 15 and by applying multivariate analysis of similarities between feature amounts extracted and feature amounts stored by disease in the storage unit 12. Results of assessment are shown as scores expressing similarity with each disease group in a bar graph.

摘要： 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.

摘要： A response period is determined arbitrarily. A satisfactory detecting ability may not be provided because of an artifact or the like contained in a signal. Therefore, an effective detection method and an effective display method of presenting results of detection must be developed. A series of tasks (stimuli) or a selected measurement signal is used as a reference signal, and a phase difference of any other measurement signal from the reference signal is calculated. The synchronousness of the phase of the measurement signal with the phase of the reference signal is numerically expressed. The thus obtained numerical value is statistically processed in order to numerically express a degree of reliability. Thus, a brain activity or a functional connectivity is visualized.

摘要： A principal component analysis or an independent component analysis is conducted on the living body signals, e.g., local cerebral blood amount change signals obtained by the living body optical measurement to extract and display multiple component signals thereof. Signals other than the component signals containing noise are selected from these component signals automatically or manually, and the local cerebral blood amount change signals are reconstructed by using selected signals. The reconstructed signals is displayed and further subjected to the component analysis or the reconstruction as appropriate, and used for the profiling of information necessary for the diagnosis. Consequently, high-precision target signals can be obtained by completely removing external noise included in the living body signals, particularly the noise which cannot be adequately removed by the moving average and the filtering processings.
