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..
