Radial jet vortical events are better delineated on 3D reconstructions of flow images than on 2D color Doppler: An in vitro study with comparisons to optical visualization of flow jets

Abstract

Entrainment and vortical structures are sometimes clearly visualized in longitudinal views of flowing lets by optical visualization methods. These events also occur radially around the direction of propagation. However, vortical events are often poorly visualized on color coded flow maps because of the angle-dependence of color Doppler encoded images in 2D planar views. We performed rotational 3D reconstruction of pulsatile jet flows using a a TomTec imaging system, an Interspec ATL annular array, and a customized color map to facilitate composite video transfer of subtle low velocity color dynamics into the grey scale TomTec milieu.
