Aide au diagnostic cardiovasculaire par superposition en 2 et 3D des images de coronarographie et tomoscintigraphie : segmentation de l'arbre coronaire et représentation 3D

Abstract : This work contributes to the conception of a diagnosis aid tool for coronary diseases. Currently, this diagnosis is done with two exams (coronarography, tomoscintigraphy) providing two complementary information: the arteries anatomy and the myocardium perfusion. The aim is creating a new multi-modal image showing clearly the link between both information (stenosis and ischemia) by registrating and superimposing data both in 2D and 3D. The first part deals with the automatic segmentation of arteries on coronarography in order to distingllish vessels of each side. Then, the related perfusion data is superimposed in 2D. The second part proposes an algorithm free from any acquisition systems dimensions as we use registration results. Using homologous points, arteries are 3D-reconstructed and the patient schematic tree is superimposed on his perfusion volume. This way, the link between stenosis and perfusion is clearly shown. Tests have been done on a phantom and nine patients.
