PULSE WAVE PROPAGATION SPEED CALCULATION SYSTEM, PULSE WAVE PROPAGATION SPEED CALCULATION METHOD, AND PULSE WAVE PROPAGATION SPEED CALCULATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a pulse wave propagation speed calculation system, a pulse wave propagation speed calculation method, and a pulse wave propagation speed calculation program which calculate a pulse wave propagation speed from an image.;SOLUTION: The pulse wave propagation speed calculation system 1: acquires an image; divides the image; detects, for each of the blocks into which the image is divided, a biological reaction from a luminance signal in the block; classifies, by living body, biological regions, each comprising one or more blocks in which a biological reaction is detected; identifies the site of a biological region from the luminance signal in the biological region between a plurality of biological regions classified into the same living body; and calculates a pulse wave propagation speed from the time difference of luminance signals obtained between identified sites.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
