Medical diagnostic ultrasound system and method for identifying constrictions

摘要

A method and system for identifying constrictions in a vessel are provided. Total blood volume flow is measured at various locations along the vessel. The total volume flow must be conserved. Regions with a different volume flow than expected (e.g. areas associated with a lower volume that violates conservation of flow) are identified as suspicious. Suspicious regions are likely associated with dropout artifact. Actual constrictions are determined from the geometry of images where the region is not suspicious.
