Viscosity characteristics acquisition device, viscoelastic characteristics acquisition method, viscoelastic characteristics acquisition program, and recording medium for recording the program

摘要

A viscoelastic characteristics acquisition device is a device that acquires viscoelastic characteristics of a blood vessel of an inspection target, and includes a pulse wave acquisition unit that acquires a time waveform corresponding to a volume pulse wave of the inspection target, a spectrum acquisition unit that acquires a volume pulse wave spectrum by performing Fourier transform on the time waveform, an input unit to which values corresponding to maximum blood pressure and minimum blood pressure of the inspection target are input, and an analysis unit that acquires the viscoelastic characteristics on the basis of the values corresponding to the maximum blood pressure and the minimum blood pressure and the volume pulse wave spectrum at a frequency equal to or higher than a frequency corresponding to the pulse of the inspection target.
