PROCÉDÉ DE PLANIFICATION DE GÉOMÉTRIE DE BALAYAGE DESTINÉ À DÉTERMINER UNE ÉPAISSEUR DE PAROI D'UN DÉTAIL ANATOMIQUE PAR IMAGERIE PAR RÉSONANCE MAGNÉTIQUE
A method for determining wall thickness of an anatomic detail (52), in particular of the heart, of a subject of interest (20) by magnetic resonance imaging, comprising steps of - defining (82) a first location (54) and a second location (56) on a surface representation; - generating (84) a line-structure of interest (60), - determining (86), for each location (62) of a plurality of locations (62), a normal direction (64); - determining (88) a mean normal direction (66); - determining (90) a mean imaging plane (68); - determining (92) a measure that is representative of angular deviations (Δβi) of the determined normal directions (64); - based on the determined measure, determining (96) imaging planes (70); - determining (98) deviations of the determined normal directions (64) to the imaging planes (70); - acquiring (100) magnetic resonance images for all imaging planes (68, 70); and - determining (102) the wall thickness at a specific location (62) from the magnetic resonance image acquired in that imaging plane (70) that has the lowest angular deviation to the normal direction (64) at the specific location (62); a magnetic resonance imaging system (10) having a control unit (26) that is configured to carry out steps (78-102) of such a method; and a software module (50) for carrying out such a method, wherein the method steps (78-102) to be conducted are converted into a program code that is implementable in a memory unit (28) and is executable by a processor unit (30) of the magnetic resonance imaging system (10).La présente invention concerne un procédé destiné à déterminer une épaisseur de paroi d'un détail anatomique (52), en particulier du cœur, d'un sujet d'intérêt (20) par imagerie par résonance magnétique, comprenant les étapes consistant à - définir (82) un premier emplacement (54) et un second emplacement (56) sur une représentation de surface ; - générer (84) une ligne-structure d'intérêt (60) ; - déterminer (86), pour chaque emplacement (62) d'une plural
