Abstract A method to perform 4D (3D over time) seg-
mentation of the left ventricle of a mouse heart using a
set of B mode cine slices acquired in vivo from a series
of short axis scans is described. We incorporate previ-
ously suggested methods such as temporal propagation,
the gradient vector flow active surface, superquadric
models, etc. into our proposed 4D segmentation of the
left ventricle. The contributions of this paper are incor-
poration of a novel despeckling method and the use of
locally fitted superellipsoid models to provide a better
