Experience

Deniz Aykac has worked on various projects involving both hardware and software for routine use in Positron Emission Tomography (PET) Center at the University of Iowa. These would include software design and development for real time logging of personnel radiation monitoring devices and GUI development for remote, automated [F-18] water target loading system. She has extensive software experience in 3D medical image analysis. She worked on a fully automatic technique for segmenting the airway tree in 3D CT images of the thorax using grayscale morphological reconstruction. Her experience at Oak Ridge National Laboratory (ORNL) would include the development of an automatic model-driven tool to segment structures in mice using high-resolution small animal microSPECT/CT imaging technology by implementing the Active Appearance Model (AAM), GUI design providing the ability to simultaneously view anatomical and functional information derived from SPECT/CT imaging system and image–based statistical analysis of mitotic spindles acquired using confocal microscopy. She is currently a member of the Imaging, Signals, and Machine Learning Group at ORNL, where she is involved in the quantitative analysis of disease progression and regression as a result of therapeutic intervention in amyloid burdened mice using high resolution dual modality SPECT/CT imaging.
