Publications by authors named "David Viar-Hernandez"

Synopsis of recent research by authors named "David Viar-Hernandez"

  • - David Viar-Hernandez's research primarily focuses on enhancing adaptive radiotherapy (ART) and proton therapy through advanced imaging techniques, particularly the synthesis of dual-energy CT (DECT) from cone beam computed tomography (CBCT) scans, aiming to improve treatment precision and minimize risks to surrounding tissues.
  • - His studies include innovative applications of machine learning, such as the use of denoising diffusion probabilistic models and 3D vision transformers to generate synthetic CT images, bridging the gap in using CBCT for accurate dose calculations in adapted proton therapy.
  • - Additionally, Viar-Hernandez investigates the evolution of medical imaging software and its effects on the field, analyzing four notable open-source platforms and their contributions to medical imaging through citations and code evolution metrics.
