摘要

PROBLEM TO BE SOLVED: To non-invasively obtain more correct viscosity.;SOLUTION: A fluid viscosity calculating device includes: a numerical value simulation section 21 for performing simulation to analyze a flowing field using two different viscosities for a fluid of a subject; a feedback section 22 for feeding back a differential vector between a velocity vector of the fluid obtained by the simulation section 21 and a velocity vector of the fluid obtained based on an ultrasonic echo signal transmitted to the subject; a specifying section 3 for specifying, of the two viscosities, a viscosity deviated from the viscosity of the fluid on the basis of the simulation performed by the simulation section; a viscosity setting section 4 for changing the a viscosity specified by the specifying section 3, of the two viscosities, to set a changed viscosity approximated to the other viscosity; and a viscosity calculating section 6 for, when the difference between the changed viscosity and the other viscosity is within a predetermined range, calculating the viscosity of the fluid from the changed viscosity and the other viscosity.;COPYRIGHT: (C)2014,JPO&INPIT
