SYSTÈMES ET PROCÉDÉS POUR FOURNIR UNE SENSIBILISATION DE PROXIMITÉ DES LIMITES PLEURALES, STRUCTURES VASCULAIRES ET AUTRES STRUCTURES INTRA-THORACIQUES CRITIQUES PENDANT UNE BRONCHOSCOPIE PAR NAVIGATION ÉLECTROMAGNÉTIQUE
A system for providing proximity awareness to an anatomical feature, the system comprising:an electromagnetic navigation system (10) including:an electromagnetic field generator (76),a treatment tool (104) configured to be inserted into the patient's chest, andan electromagnetic sensor (94) disposed on the treatment tool； anda computing device (80) including a processor (204) and a memory (202) storing instructions which, when executed by the processor, cause the computing device to: receive (S302) image data of the patient's chest；generate (S304) a three-dimensional (3D) model of the patient's chest based on the received image data；determine (S306) a location of the anatomical feature based on the received image data and the generated 3D model；track a position of the electromagnetic sensor；iteratively determine (S318) a position of the treatment tool inside the patient's chest based on the tracked position of the electromagnetic sensor；provide instructions to indicate a proximity of the treatment tool relative to the anatomical feature, based on the determined position of the treatment tool inside the patient's chest；wherein the instructions further cause the computing device to:determine (S312) a projected ablation zone (610)；determine (S314) whether the projected ablation zone encroaches on the location of the anatomical feature； andprovide (S316) an alert when a determination is made that the projected ablation zone encroaches on the location of the anatomical feature.
