3-D flow velocity vector estimation with a triple-beam lens transducer-experimental results
Current commercial ultrasound blood flow measurement systems only measure the axial component of the true blood flow velocity vector. In order to overcome this limitation, a technique which tracks blood cell scatterers as they move between three ultrasound beams has been developed. With this techniq...

| Zusammenfassung: | Current commercial ultrasound blood flow measurement systems only measure the axial component of the true blood flow velocity vector. In order to overcome this limitation, a technique which tracks blood cell scatterers as they move between three ultrasound beams has been developed. With this technique, the entire 3-D blood flow velocity vector can be estimated. Previous work has presented the theory behind the technique, lens transducer design and construction, as well as results of computer simulations and preliminary experimental results. This work presents the first experimental results obtained with a prototype system for continuous, fully developed flow in a flow phantom under a wide range of flow rates and flow directions. The results indicate that the accurate measurement of the 3-D flow velocity vector using this technique is possible |
