Doppler measurement on fetal heart is the basis of the modern methods for early diagnosis of prenatal deceases. A large-scale technology for Doppler monitoring of fetal intracardiac hemodynamics making use inexpensive fetal Dopplers is supposed to cut prenatal morbidity as much as twice. The key task here is the development of technology for smart on-line measurement accom-panied with cloud computing. Such an approach required creation of a model for Doppler measurement of intracardiac bloodflow. It is restricted to four trans-valvular flows. Large aperture of the fetal Doppler up to 30 degree and more is considered. That is why they feature large sample volume. It has the whole volume reach. However the time-space selectivity of Doppler measurements is assisting to draw infor-mative flows and exclude the noisy ones. An application is developed to implement two-view model generation - the stereometric view and the kinetic one. The software generator serves as the simulator of an adaptive control system to drive a Doppler to a position for measurement of intracardiac hemodynamics indices. It is demonstrated at four-valve blood flow model that spatial filtering is capable to extract any of those four Doppler shift simulation kinetics attenuated as low as 3÷6 dB. In the same time, influencing of interfering flows decreesed down to 20 db and lower.
