INCREASED SENSITIVITY FOR 4-D DOPPLER ULTRASOUND IMAGING

For real-time Three Dimensional ultrasonic Doppler imaging, a number of techniques are combined in order to increase detection sensitivity. This disclosure is directed, primarily, to improved filter design employing transient removal (34), mean removal (27, 30, 31) and/or trend removal (29, 33). Sel...

Beschreibung
Zusammenfassung:	For real-time Three Dimensional ultrasonic Doppler imaging, a number of techniques are combined in order to increase detection sensitivity. This disclosure is directed, primarily, to improved filter design employing transient removal (34), mean removal (27, 30, 31) and/or trend removal (29, 33). Selon l'invention, un certain nombre de techniques sont combinés en vue d'augmenter la sensibilité de détection destinée à l'imagerie Doppler ultrasonore tridimensionnelle en temps réel. Cette invention a pour objet principal d'améliorer la conception de filtres utilisant le retrait transitoire (34), le retrait moyen (27, 30, 31) et/ou le retrait de tendance (29, 33).
