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