FLOW-RATE CONSERVATIVE DOPPLER ESTIMATE

摘要

A new method is introduced to evaluate the flow through a constriction based on Doppler data and the principle of mass conservation. This principle, properly inserted within a combination of data rearrangements allows the extraction of the complete velocity field and the optimal evaluation of the flow through the constriction. The digital implementation of the method into electronic equipments, like an echographic machine, gives an additional capability of quantifying specific valvular flows and improves diagnostic potential.
