    摘要： A medical apparatus (1100) comprising a magnetic resonance imaging system and an interventional device (300) comprising a shaft (302, 1014, 1120). The medical apparatus further comprises a toroidal magnetic resonance fiducial marker (306, 600, 800, 900, 1000, 1122) attached to the shaft. The shaft passes through a center point (610, 810, 908, 1006) of the fiducial marker. The medical apparatus further comprises machine executable instructions (1150, 1152, 1154, 1156, 1158) for execution by a processor. The instructions cause the processor to acquire (100, 200) magnetic resonance data, to reconstruct (102, 202) a magnetic resonance image (1142), and to receive (104, 204) the selection of a target volume (1118, 1144, 1168). The instructions further cause the processor to repeatedly: acquire (106, 206) magnetic resonance location data (1146) from the fiducial marker and render (108, 212) a view (1148, 1162) indicating the position of the shaft relative to the target zone.

    摘要： A magnetic resonance imaging method involves acquisition of magnetic resonance signals with application of diffusion weighting at a plurality of diffusion weighting strengths diffusion directions. An object dataset is reconstructed from the magnetic resonance signals in which apparent diffusion coefficients are assigned. The occurrence of one single or several diffusion directions in identified for individual voxels. In this way account is taken of crossing fibres.

    摘要： A medical image system (100)for enables a user to navigate through three-dimensional 3D image data showing an anatomical structure by simultaneously displaying a set of views of the 3D image data showing the anatomical structure. The system includes a data input (140) for receiving orientation data (142), a user input (120) for receiving a navigation command (122)from the user, a plane processor (160) for, in dependence on the navigation command, adjusting a spatial configuration of a set of planes (102) for obtaining a further set of planes (162) intersecting the 3D image data, and a view processor (180) for, in dependence on the further set of planes and the orientation data, establishing a further set of views (182) of the 3D image data for displaying the further set of views as an update of the set of views.
