Measurement-integrated (MI) simulation, in which feedback signals are applied to the governing equations based on errors between measurement and numerical simulation, has been investigated to solve various problems related to fluid flows. As medical applications of MI simulation, the authors have proposed integration of medical measurement, such as ultrasound Doppler measurement or phase-contrast MRI (PC MRI), of blood flow velocity and a numerical simulation. Effects of feedback of errors in one- or three-directional velocity information between ultrasound Doppler measurement or PC MRI and the numerical simulation were examined by numerical experiments, respectively. Each MI simulation converged to the standard solution and yielded the hemodynamic stresses accurately and in detail.
