Multi-Contrast MRI Synthesis Using Generative Adversarial Networks
Multi-contrast MRI—including T1-weighted contrast-enhanced (T1-CE), T2-weighted (T2), and T2-FLAIR—is essential for brain radiotherapy planning but increases scan time, patient discomfort, and exposure to gadolinium-based contrast agents (GBCA). We propose a...

Ultra-Sparse View Reconstruction of CBCT Using an Adversarial Implicit Neural Representation
In image-guided radiation therapy (IGRT), cone-beam CT (CBCT) reconstruction typically requires 300–600 projections to achieve acceptable image quality, which contributes to imaging dose and acquisition time. This study investigates the feasibility of reconst...
