ABSTRACT
Segmenting dynamic contrast enhanced-MRI series of small
animal, which are intrinsically noisy and low contrasted im-
ages with low resolution, is the aim of this paper. To do
this, a segmentation method taking into account the tempo-
ral (spectral) and spatial information is presented on several
series. The idea is to start from a temporal classification, and
to build a probability density function of contours condition-
ally to this classification. Then, this function is segmented to
find potentially tumorous areas. The method is presented on
