用在受測者目標區域之具移動式線圈之磁振造影裝置及具有該裝置之治療系統,其中該磁振造影裝置係主要包含用於從該受測者接收磁振訊號之移動式線圈和固定式線圈,該移動式線圈可結合治療用換能器,連接於一定位裝置且在該受測者之目標區域內具不受限制之移動作用,該固定式線圈大於該移動式線圈且具有超過該移動式線圈之較大視野,該磁振造影裝置更包含一影像處理裝置以處理從該移動式線圈和該固定式線圈接收到的磁振訊號以形成一磁振造影影像。A device with a movable coil and a therapeutic system is used for therapeutic applications in a magnetic resonance imaging system. The device consists of a moveable coil and a fixed coil for receiving the magnetic resonance signal from the subject. The moveable coil is attached to a positioning device and is able to move together with a therapeutic device over the target area of subject. The fixed coil is larger than the movable coil and has a larger field of view than that of the movable coil. The device further includes an imaging processing unit to reconstruct the received signals from the moveable coil and the fixed coil to form an MRI image.
