Biosketch

Dr. Vicente is a nuclear physicist by training working in the field of medical imaging with applications in diagnostic nuclear medicine and in radiation therapy (RT), specifically in the area of stereotactic ablative RT (SAbR or SBRT). Her current work and main research interest are focused on the use of clinical anatomical and functional imaging techniques to improve the state of the art in lung RT treatment planning, in order to preserve post-RT respiratory function. She is developing new lung functional-avoidance RT frameworks which combine virtual bronchoscopy-derived airway maps with lung functional maps (4DCT-derived ventilation maps or SPECT-based ventilation/perfusion maps) to maximize the preservation of both serial and parallel functioning structures of the lung during the RT plan.

Her research background encompasses the study of preclinical and clinical imaging techniques used in diagnostic nuclear medicine. Some of the main lines of research Dr. Vicente was involved are the performance evaluation of preclinical PET/CT systems, the use of  Monte Carlo (MC) simulation methods to study and mitigate the sources of error that limit the quality of the preclinical PET images, the investigation of novel preclinical PET scanner designs and reconstruction algorithms for the new geometries, and the analysis of the different factors that determine the repeatability in clinical SPECT by means of patient data, MC simulations and bootstrap techniques.

Research/Clinical Keywords

Medical imaging, airways, dose estimation, lung radiotherapy, stereotactic ablative radiotherapy, SBRT, lung functional-avoidance radiotherapy, motion management.
