Innovative Methods of Archiving, Presentation and Providing Access to Histological Sections

The dynamic development of technical sciences and informatics makes now possible acquisition of microscopic images of histological sections, not only using digital cameras, but also through specialized devices called scanners. The digitalized images 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 screen by panoramic viewing or using a detailed image examination at higher magnification. In many research and education institutions in both the U.S. and Europe, the virtual microscopy is used for teaching and training purposes. In the academic year of 2009/10, Department of Histology and Embryology, University of Medical Sciences in Poznan, as one of the first in Poland, has created a virtual database for educational purposes. This database created by 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 uses 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 has launched an online platform (www.caom.pl), aimed to provide the central database of scanned histological sections of physiological tissues, and pathological, rare and sporadic lesions, including tumor
