The present invention relates to a computer-aided method to estimate the coil volumes using only two orthogonal angiographic projections and Non-invasive Vascular Elastography: Theoretical Framework. The invention relates to the validation on tissue mimicking phantoms of non-invasive elasticity imaging in small vessels. The Lagrangian speckle tissue model estimator was used to assess the 2-D-strain tensor, and the composite Von Mises elastograms were computed. The invention also relates to a model-based approach devoted to endovascular elastography (EVE). A model-based approach is proposed and the Lagrangian speckle model estimator is provided and the theoretical framework is validated. Moreover, the invention relates to the in vitro experiments using excised human carotid artery to validate the potential of endovascular elastography to detect hard plaques.
