摘要：

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 rotational acquired three-dimensional 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 two-dimensional echocardiography. A hybrid visualisation technique enables a simultaneous display of surface rendered annulus together with volume rendered flow patterns and/or the morphology.
