Hausdorff distance based 3D quantification of brain tumor evolution from MRI images.

ABSTRACT

This paper presents a quantification method which can be used to quantify the evolution of a brain tumor with time. From two segmented volumes, a Local Distance Volume (LDV) based on Hausdorff Distance is computed to show the true physical local distances between them. In the case of tracking a tumor volume during a therapeutic treatment, local variations can thus be shown by the LDV in particular where the tumor has regressed and where it has grown. This information can help radiologists to adapt the current treatment.
