Rapid 4D-MRI reconstruction using a deep radial convolutional neural network: Dracula
Magnetic resonance (MR) guided radiotherapy (MRgRT) harnesses the exquisite soft-tissue contrast of magnetic resonance imaging (MRI) to improve the conformity of radiotherapy treatment delivery and subsequently patient outcome [1 –3]. For abdominal and lung cancer patients, four-dimensional (4D) and midposition [4,5] (MidP; time-weighted mean position within respiratory cycle) MRI have many applications on an MR-Linac [6–14]. For instance, 4D/MidP-MRI could be acquired online before treatment delivery (pre-beam) and info rm treatment plan adaptation to better represent the daily patient anatomy and respiratory pattern [15–17].
