Dr. Žagar’s research is mainly focused on multimedia applications and high-performance computing with its applications in telemedicine. More specifically, his research is most recently oriented on medical diagnostics to be performed in a collaborative, distributed and mobile environment; multidimensional compression of medical data; contactless surgery; electronic health record; medical imaging and other e- and m-health applications. As a part of research on contactless surgery,
Dr. Žagar with his collaborators has developed a special plug-in application for DICOM (standard for digital medical images) viewer, enabling users to use a motion-tracking sensor as an interface for camera positioning in 3D Volume Rendering (3DVR) and Virtual Endoscopy (VE) views. They defined different types of gestures for 3DVR and VE, which enable navigation through virtual 3D space, adjusting the viewing angle and camera position, using only one hand. Consequently, this has minimized surgeon distraction while interacting with the positioning system. Results are published in several conference and journal papers.
Aside from his primary research track, Dr. Žagar has also developed the framework for multidimensional medical data compression and a framework for the medical image diagnostics on the move. He is also working together with professors from the Rochester campus (Prof. Zilora, Prof. Patric, Prof. Keller) and Dubai campus (Prof. Raza) on delivering international capstone projects for IT students as a real international joint multicampus project in collaboration with the industry partners.
Dr. Žagar has published more than sixty publications including book and book chapters, highly indexed journal articles and conference proceedings, and technical reports. He is a Member of IEEE, AASCIT (American Association for Science and Technology), HiPEAC (European Network on High Performance and Embedded Architecture and Compilation), EAIE (European Association for International Education) and Croatian Academy of Science, and editor and reviewer in a couple of international journals.
