Abstract

Changes in mitral annular shape and dynamics are associated with mitral regurgitation without valvular disease. Therefore, it is interesting to visualise the annulus together with the regurgitant flow patterns. A prerequisite for a clear visualisation is the segmentation of the annulus. We present a specialised method for annular segmentation in rotationally-acquired 3D transesophageal echocardiographic data. For visualisation, a surface model of the annulus is constructed, while we use a volume rendering method for flow patterns, which allows the display in the original colour coding from 2D echocardiography. A hybrid visualisation technique enables a simultaneous display of the surface-rendered annulus together with volume-rendered flow patterns and/or morphology
