Project: Evaluation of Deformable Image Registration for Improved 4D CT Ventilation Image Generation.

My research broadly encompasses deformable image registration (DIR) of medical image volumes and functional lung imaging from 4D CT. Deformable registration is a quickly developing technology with many potential applications in diagnostic imaging and radiotherapy. However, methods for evaluation and formal validation of novel DIR models and implementations are lacking. My research in this area involves methodological and statistical methods for quantitative evaluation of DIR spatial accuracy for purposes of validation and acceptance testing, as well as quality assurance in routine clinical application. I am also interested in methods for utilizing DIR output to extract functional information, including quantitative pulmonary ventilation and perfusion, from treatment planning 4D CT. The incorporation of such function information into radiotherapy treatment planning for purposes of functional avoidance may prove to be a potentially superior planning practice for the treatment of thoracic malignancies.
