Patent ID: 7463916

Claim:
An optical measurement apparatus for examination of a living body comprising: light transmitting means for transmitting light to a plurality of positions in an area being examined within a living body; light detecting means for detecting light which has been transmitted by said light transmitting means and has passed through the living body at a plurality of positions in the area being examined; means for calculating signals representing the intensity change of transillumination detected by said light detecting means at measuring points that are determined based on a positional relation between said light transmitting means and said light detecting means, during a period in which a load is applied to the living body and periods in which the load is not applied; means for calculating time variations of at least one signal among two signals calculated at the measuring points that are determined based on the positional relation between each of said light transmitting means and said light detecting means; means for converting the calculated time variations of the light signal at each measuring point into time variations of hemoglobin concentration; and display control means for displaying graphs of the calculated time variations of hemoglobin concentration in correspondence with the positional relation between each of said light transmitting means and said light detecting means; and means for selecting and classifying graphs displayed by said display control means on display means so as to display plural groups of graphs.
