Patent ID: 7353054

Claim:
An optical measurement apparatus for a living body comprising a light source for generating a light to be irradiated onto an object to be examined, a light measurement means that detects a light transmitted inside the object and generates hemoglobin signals corresponding to hemoglobin changes in the object, an assessing means that analyzes feature amounts of the hemoglobin signals and assesses a disease of the object from the analyzed feature amount, and a display means for displaying disease information of the object, wherein said assessing means comprises: an extracting means for extracting various kinds of feature amounts from the hemoglobin signals, a storing means for storing feature amounts of hemoglobin variation signals of multiple diseases in a database; analyzing means for calculating a similarity of extracted feature amounts of an acquired hemoglobin variation signal with stored feature amounts of hemoglobin variation signals characterizing the multiple stored diseases in order to diagnose a disease of a subject; and a guantifying means for guantifying the similarity estimated by the analyzing means.
