Title (EN) SYSTEM AND METHOD FOR PROVIDING SURGICAL GUIDANCE BASED ON POLARIZATION-SENSITIVE OPTICAL COHERENCE TOMOGRAPHY
(FR) SYSTÈME ET PROCÉDÉ DE GUIDAGE CHIRURGICAL FONDÉ SUR LA TOMOGRAPHIE PAR COHÉRENCE OPTIQUE SENSIBLE À LA POLARISATION
Abstract:
(EN) Systems and methods are provided for identifying a suitable surgical location and/or trajectory for proceeding with a surgical procedure based on local polarization- sensitive optical coherence tomography imaging (PS-OCT). PS-OCT images are obtained of a tissue region and are processed to provide a spatial map of anisotropic structure within the tissue region. The anisotropic structure is processed to determine one or more suitable surgical locations and/or trajectories for avoiding or reducing damage to local anisotropic tissue structure identified within the tissue region. The spatial map of the anisotropic structure is registered with pre-operative volumetric image data identifying anisotropic tissue structure within a second tissue region that is larger than the tissue region imaged by PS-OCT.
(FR) L'invention concerne des systèmes et des procédés permettant d'identifier une zone et/ou une trajectoire chirurgicale appropriée pour procéder à une intervention chirurgicale sur la base de l'imagerie par tomographie par cohérence optique sensible à la polarisation localisée (PS-OCT) On obtient des images de PS-OCT d'une région tissulaire, images qui sont traitées pour fournir une carte spatiale de la structure anisotrope de la région tissulaire. La structure anisotrope est traitée pour déterminer une ou plusieurs zones et/ou trajectoires chirurgicales appropriées pour éviter ou réduire les dommages à la structure tissulaire anisotrope locale identifiée à l'intérieur de la région tissulaire. La carte spatiale de la structure anisotrope est enregistrée avec des données images volumétriques préopératoires d'identification de la structure tissulaire anisotrope à l'intérieur d'une seconde région tissulaire qui est plus grande que la région tissulaire imagée par PS-OCT
