    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 fiducial position marker (1) for use in a magnetic resonance (MR) imaging apparatus is disclosed for exciting and/or receiving MR signals in/from a local volume which at least substantially surrounds or adjoins the position marker, in order to determine and/or image from these MR signals the position of the position marker in an MR image of an examination object. Such a position marker (1) is especially used for determining and/or imaging a position of an interventional or non-interventional instrument to which the position marker may be attached, like a catheter, a surgical device, a biopsy needle, a pointer, a stent or another invasive or any non-invasive device in an MR image of an examination object. Further, a position marker system comprising such a position marker (1) and a circuit arrangement (5, 6, 6a, 8) for driving the position marker (1) for exciting MR signals and/or for processing MR signals received by the position marker is disclosed.
