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 combined magnetic resonance (MR) and radiation therapy system (10) includes a bore-type magnet (12) with a magnet radiation translucent region (16) which allows radiation beams to travel radially through the magnet and a split-type gradient coil (18) includes a gradient coil radiation translucent region (20) aligned to the magnet radiation translucent region (16). A radiation source (24), disposed laterally to the magnet, administers a radiation dose through the magnet and gradient coil radiation translucent regions (16, 20) to an examination region (14). A dosage unit (66) determines the actual radiation dose delivered to each voxel of a target volume (30) and at least one non-target volume based on a pre-treatment, intra-treatment, and/or post-treatment image representation of the target volume (30) and the at least one non-target volume. A planning processor (60) updates at least one remaining radiation dose of a radiation therapy plan based on the determined actual radiation dose.
