At the state of the art some semiautomatic and automatic segmentation procedures have been described. Current methods dont mind geometric and physical constitution of anatomical structures, not making a physically justified segmentation. This implies 8-9% volume errors, low methods concordance and low adaptability. We realized an automatic method for MRI, CT, CTA deterministic segmentation, based on mathematical modelling and analysis of anatomical structures physical and geometrical properties. It has been applied for several structures segmentation, as brain, grey-white matter, heart, kidneys, urinary tracts and bone. It is characterized by high precision (volume error 4.5%), non subjective parameters and high adaptability.
