摘要:
The invention relates to a method and a system for helping to guide an endovascular tool in vascular structures, comprising an initial planning phase (P1) in which a first three-dimensional anatomical model specific to the patient is determined (52) from an acquired three-dimensional image, and an intervention phase (P2) in which a final transformation, a combination of a rigid transformation and of an elastic transformation, is applied (60) 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 (56) 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 (58) as a function of a simulation of vascular deformations that are induced by introducing the tool into the target vascular structure.
