Nowadays, virtual reality is a new and rapidly developing technology that provides
the opportunity for a new, more immersive form of data visualization. Evaluating digitized
pathological serial sections and establishing the appropriate diagnosis is one of
the key task of the pathologist in the daily work. The type of tools used by pathologists
in the evaluation of samples has not changed much in recent decades. On the other
hand, the amount of information required to establish an accurate diagnosis has been
significantly increased. Nowadays, pathologists are working with the help of multiple
high-resolution desktop monitors. Instead of the large screens, the use of virtual
reality can serve as an alternative solution, which provides virtualized working space
for pathologists during routine sample evaluation. In our research, we defined a new
immersive working environment for pathologists. In our proposed solution we visualize
several type of digitized medical image data with the corresponding meta data in 3D,
and we also defined virtualized functions that support the evaluation process. The
main aim of this paper is to present the new possibilities provided by 3D visualization
and virtual reality in digital pathology. The paper presents a new virtual reality-based
examination environment, as well as software functionalities that are essential for
3D pathological tissue evaluation.
