The aim of this study was to establish the reproducibility of sequential th
ree-dimensional (3D) ultrasound reconstructions of an identified segment of
the carotid artery bifurcation in asymptomatic subjects. A freehand acquis
ition, compound reconstruction, 3D ultrasound system was used on three occa
sions, over a period of 1 year. The lumen of the vessel was reconstructed t
o provide a volume measurement and a rotatable 3D structure representation
that could be examined for geometrical correspondence. The four subjects di
ffered significantly in the visualized 3D geometry of the vessel bifurcatio
n. There was good correspondence in the sequential reconstructions for each
individual in both the 3D geometry and in the measured lumen volume, with
an overall coefficient of variation of 5% and no evidence of deterioration
in correlation with time.
