Method of scan geometry planning for determining wall thickness of an anatomic detail using magnetic resonance imaging

Abstract

A method for determining wall thickness of an anatomic detail (), in particular of the heart, of a subject of interest () by magnetic resonance imaging includes: defining () a first location () and a second location () on a surface representation; —generating () a line-structure of interest (), —determining (), for each location () of a plurality of locations (), a normal direction (); —determining () a mean normal direction (); —determining () a mean imaging plane (); —determining () a measure that is representative of angular deviations () of the determined normal directions (); —based on the determined measure, determining () imaging planes (); —determining () deviations of the determined normal directions () to the imaging planes (); —acquiring () magnetic resonance images for all imaging planes (); and —determining () the wall thickness at a specific location () from the magnetic resonance image acquired in the imaging plane () that has the lowest angular deviation to the normal direction () at the specific location (). A magnetic resonance imaging system () has a controller () configured to carry out steps (-) of the method. A software module () carries out the method by implementing program code from a memory () and executed by a processor () of the magnetic resonance imaging system ().
