Cone beam CTs at typical kV energies exhibit metal artifacts in IGRT patients with metal prosthetics. MV-CBCT, available on some linacs, reduces artifacts at the expense of soft tissue contrast-to-noise (CNR). As a remedy, we propose an AI network to convert...

While image translation models like CycleGANs are increasingly used in medical imaging tasks, evaluating their training behavior remains challenging. Current practices often rely on batch-wise loss curves or selected visual outputs, both of which can be noisy...
Spine stereotactic body radiation therapy (SBRT) is an emerging standard of care for patients with symptomatic spinal metastatic disease. The accuracy of target volume delineation is of critical importance for safe and effective spine SBRT. The adjacent norma...
Conventional dual-energy material decomposition methods suffer from significant noise amplification, which limits their clinical utility for tasks such as intra-fraction markerless tumor tracking. This study introduces PRISM, an open-source Julia framework sp...
Spectral imaging confers several benefits such as material decomposition, increased soft tissue contrast, and metal artifact reduction. Novel methods currently under evaluation for adoption to linac onboard imaging include a kV dual-layer imager investigated...
