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.
