Evangelia Karali

She is a graduate of the Physics Department of the Faculty of Science of the National and Kapodistrian University of Athens. During her studies she attended courses such as: Health Physics, Medical Physics, Bioelectronics and Biology, which helped her a lot to gain very good knowledge in the field of Medical Physics and turned her interest to Biomedical Technology.

As part of the postgraduate study course in Biomedical Technology, she dealt with various branches of Medical Informatics, such as safety in Telemedicine and medical image processing. She also studied specialized imaging systems such as CCD cameras and modern electronic microscopes.

As part of the postgraduate course in Automation Systems, she dealt with areas such as Automation in Production, Digital Automatic Control Systems, Intelligent Automatic Control Systems, Simulation (matlab) of Robotic Arrangements, Fault Detection in Industrial Facilities, CAD, Sensor Technologies, Programming of real robotic arrangements, Smart Materials. She also studied Antipollution Processes and Techniques which is a field with intense and current research work.

Her doctoral thesis has as its central topic Positron Emission Tomography (PET). She simulated a prototype PET system capable of small animal imaging and performed a comparative study of existing iterative algorithms for data reconstruction from this system. The benchmarking resulted in the introduction of a new iterative algorithm under the name IS-WLS (Image Space Weighted Least Squares).

Her general research activity is oriented towards the study and simulation of the various imaging systems of Nuclear Medicine, i.e. SPECT and PET tomographic systems. Her research focuses on data processing and analysis methods from the specific imaging systems, such as scatter correction methods, attenuation correction methods and mainly techniques for reconstructing the image of the spatial distribution of the radiopharmaceutical from the set of projection data collected by the Nuclear Medicine imaging systems.
