Patent number: 11551362Abstract: This invention concerns an automatic segmentation method of features, such as anatomical and pathological structures or instruments, which are visible in a 3D medical image of a subject, composed of voxels. Said method being characterised in that it consists in providing a global software means or arrangement combining N different convolutional neural networks or CNNs, with N?2, and having a structured geometry or architecture adapted and comparable to that of the image volume, and in analysing voxels forming said volume of the 3D image according to N different reconstruction axes or planes, each CNN being allocated to the analysis of the voxels belonging to one axis or plane.Type: GrantFiled: January 10, 2019Date of Patent: January 10, 2023Assignees: INSTITUT DE RECHERCHE SUR LES CANCERS DE I, VISIBLE PATIENTInventors: Luc Soler, Nicolas Thome, Alexandre Hostettler, Jacques Marescaux

Patent number: 11288812Abstract: This invention concerns an automatic segmentation method of a medical image making use of a knowledge database containing information about the anatomical and pathological structures or instruments, that can be seen in a 3D medical image of a×b×n dimension, i.e. composed of n different 2D images each of a×b dimension. Said method being characterised in that it mainly comprises three process steps, namely: a first step consisting in extracting from said medical image nine sub-images (1 to 9) of a/2×b/2×n dimensions, i.e.Type: GrantFiled: January 10, 2019Date of Patent: March 29, 2022Assignees: INSTITUT DE RECHERCHE SUR LES CANCERS DE I, VISIBLE PATIENTInventors: Luc Soler, Nicolas Thome, Alexandre Hostettler, Jacques Marescaux

Patent number: 10736497Abstract: A method and a system for anatomical site relocalisation using dual data synchronisation. Method for repositioning, possibly several times, at a specific location, which has been already explored during a first or “reference exploration”, a flexible endoscope during one or more successive endoluminal or extraluminal subsequent or “new exploration”, or similar procedures, wherein the repositioning is realized either manually, by a human user, or automatically, by a robotic system, from or by way of a synchronisation process between a “new exploration” flexible endoscope video and the “reference exploration” flexible endoscope video displayed in parallel on or in two different windows, on one or more screens.Type: GrantFiled: March 11, 2014Date of Patent: August 11, 2020Assignees: INSTITUT HOSPITALO-UNIVERSITAIRE DE CHIRURGIE MINI-INVASIVE GUIDEE PAR L'IMAGE, INSTITUT DE RECHECHE SUR LES CANCERS DE L'APPAREIL DIGESTIF—IRCADInventors: Stephane Nicolau, Anant Suraj Vemuri, Luc Soler, Jacques Marescaux

Patent number: 9717441Abstract: An automatic process of predictive determination of the position and movements of the skin of a subject in a zone of interest, with the subject breathing freely or in an assisted manner, includes preliminarily acquiring multiple configurations of the skin profile in axial planes, at given successive times, in different respiratory positions, and for each axial plane, constructing at least one deformable digital model starting from different skin profiles, then noting, in a repetitive manner, the actual position of a point on the skin at the level of each axial plane, whose position is significantly modified during inhalation and exhalation phases, and providing, essentially in real time, a simulation of the skin profile in each axial plane, as a function of the actual position noted, and an evolving three-dimensional representation of the skin at the level of the zone of interest, by interpolation between the different axial planes.Type: GrantFiled: March 3, 2014Date of Patent: August 1, 2017Assignee: INSTITUT DE RECHERCHE SUR LES CANCERS DE L'APPAREIL DIGESTIF—IRCAD (ASSOCIATION REGIE PAR LES ARTICLES 21 A 79 DU CODE CIVIL ET LOCAL ET INSCRITE AU REGISTRE DES ASSOCIATIONS DU TRIBUNAL D'INSTANCE DE STRASBOURG)Inventors: Luc Soler, Jacques Marescaux, Stephane Nicolau, Alexandre Hostettler
