Dr. Balter has over 30 years of research experience in development and optimal use of novel imaging solutions to address Radiation Oncology problems. His research has focused on a few specific areas:

  • Dynamic human modeling
  • Optimizing integration of MRI in Radiation Oncology, including development of synthetic CT models of patients to support MRI-only Radiation Therapy Simulation and investigations of sparsity for biological, morphological and motion modeling of humans from MR signals
  • Advancing precise Image-Guided Radiotherapy (IGRT)
  • Studying the complexity of therapeutic decisions and the sparsity of information sufficient to justify decisions throughout the radiotherapy process
  • Improving and evaluating the impact of alignment uncertainty on radiation therapy and related decisions
  • Projection-to-volume modeling of pose, configuration, and movement

Dr. Balter participates as an active member of the Functional Imaging Group and has industrial collaborations with Siemens Healthineers.
