Title:
LIVING BODY PHOTOMETRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2004/021889
Kind Code:
A1
Abstract:
The time-change signals of a hemoglobin concentration, at a set of stimulus loaded time and non-loaded time, are detected from a plurality of measuring points on a photometric probe-attached sample and at a plurality of channels corresponding to positions, respective detected hemoglobin change signals are subjected to a main component analysis, and a high-distribution representative signal is extracted which is then displayed on a monitor. The correlation between this representative signal and a requirement referring response waveform representing a living body's reaction pattern to a stimulus requirement is calculated, a representative signal having the highest calculated correlation value is displayed as a requirement-related signal that has reacted most strongly to a stimulus given to a sample so as to be distinguishable from other samples. A photometric point or region that has reacted most strongly to a requirement is specified from weights at respective channels on a representative signal displayed as a requirement-related signal and is distinguishably displayed.
