摘要：
A method and a system are provided for helping to guide an endovascular tool in vascular structures. The method includes an initial planning phase in which a first three-dimensional anatomical model specific to the patient is determined from an acquired three-dimensional image, and an intervention phase in which a final transformation, which is a combination of a rigid transformation and of an elastic transformation, is applied to the first three-dimensional anatomical model specific to the patient in order to obtain a second three-dimensional model specific to the patient. The rigid transformation is estimated between the preoperative three-dimensional image and one or more perioperative two-dimensional images of perioperative two-dimensional images, and the elastic transformation is calculated as a function of a simulation of vascular deformations that are induced by introducing the tool into the target vascular structure.
