BEAM3R: Beam's-eye-view architecture with Mamba-3 for implicit dose reconstruction
Chen Cheng, Michael Ferraro, James Grover +2
To enable accurate and rapid photon control point and proton beamlet dose calculation in the DoseRAD2026 challenge, we present BEAM3R, a dose estimation framework operating in beam…
Closed-loop coupling of personalised and foundation models for real-time treatment guidance with MRI
James Grover, Emily A. Hewson, Andrew Phair +5
Image-guided therapies, including radiotherapy, biopsy and deep brain stimulation, rely on real-time targeting of anatomical structures. However, in the presence of motion, imaging…
Enhancing Ultra-low-field MRI with Segmentation-guided Adversarial Learning
James Grover, Andrew Phair, Michael Ferraro +1
Ultra-low-field (ULF) MRI offers portable and low-cost imaging but suffers from poor image quality. To address this, we present our submission to the 2025 ULF Enhancement Challenge…
Accelerating Low-field MRI: From Compressed Sensing to Deep Learning Reconstruction with CNNs and Transformers
Efrat Shimron, Shanshan Shan, James Grover +7
Portable, low-field Magnetic Resonance Imaging (MRI) scanners are increasingly being deployed in clinical settings. However, key barriers to their widespread use include low signal…
