The dynamic development of technical sciences and information technology allows now for acquisition of microscopic images of histological sections, not only using digital cameras, but also through specialized devices called scanners. The images obtained using scanners and stored in a computer storage device are called virtual slides and, together with special software, are known as virtual microscopy. The virtual slides can be analyzed on a computer monitor by panoramic viewing or using a detailed image examination at higher magnification. In many research and education institutions in both the US and Europe, the virtual microscopy is used for teaching and training purposes. In the academic year of 2009/2010, Department of Histology and Embryology, University of Medical Sciences in Poznań, as one of the first in Poland, has created a virtual database for educational purposes. This database has resulted from archiving the traditional images of histological slides in the form of digital images. So far, more than 130 virtual slides have been acquired and catalogued in 24 thematic folders, available for medical students participating in histology, embryology and cell biology courses. Telepathology is the second branch which use virtual microscopy. Virtual microscope allows to discuss and resolve medical/diagnostic problems with the use of telecommunication systems and information technology. The existing internet platforms offer access to virtual microscopes and virtual slides. In June, 2011 the Center of Morphologic Images Archivization and Digital Database of Microscopic Pictures in the Department of Histology and Embryology, Poznan University of Medical Sciences launch an online platform (www.caom.pl), aimed at providing a central database of scanned histological sections with images of physiological tissues, and pathological, rare and unusual lesions, including tumors.
