BLOOD FLOW INDEX CALCULATING METHOD, BLOOD FLOW INDEX CALCULATING APPARATUS, AND RECORDING MEDIUM

摘要

A blood flow index calculating method includes: obtaining, by a camera, an image capturing a first site of a living body and a second site of the living body; extracting an area of the first site of the living body and an area of the second site of the living body, by a processor; detecting a pulse wave pattern of the first site of the living body from the area of the first site of the living body and detecting a pulse wave pattern of the second site of the living body from the area of the second site of the living body, by the processor; first calculating a delay amount from the pulse wave pattern of the first site and the pulse wave pattern of the second site, by the processor; and second calculating an index related to blood flow by using the delay amount, by the processor.

主权项

1. A blood flow index calculating method comprising:
obtaining, by a camera, an image capturing a first site of a living body and a second site of the living body, the first site being a part of the living body of a subject, and the second site being a site different from the first site; extracting an area of the first site of the living body and an area of the second site of the living body, the areas being included in the image, by a processor; detecting a pulse wave pattern of the first site of the living body from the area of the first site of the living body and detecting a pulse wave pattern of the second site of the living body from the area of the second site of the living body, by the processor; first calculating a delay amount from the pulse wave pattern of the first site of the living body and the pulse wave pattern of the second site of the living body, by the processor; and second calculating an index related to blood flow by using the delay amount, by the processor.
