Digital imaging and photography:
Launching the Practice of Pathology into the 21st Century
Jaleh Mansouri, M.D.

The advent of the digital age has revolutionized the practice and scope of pathology. The transition from film to digital photography has paved the way for the growing field of telepathology. In addition, digital technology has given rise to many novel techniques for data acquisition and analysis such as multispectral imaging. Multispectral imaging utilizes image data obtained at various wavelengths along the electromagnetic spectrum to quantitate the expression of multiple proteins at the cellular and molecular level. Researchers in pathology can apply this modality to construct molecular profiles of diseased tissue or tumors contained in tissue microarrays.

Digital pathology systems have become an essential part of many pathology laboratories in both academic centers and in the private sector. Components of a digital pathology system usually include a digital slide scanner, image analysis computer and software, and camera, and are available from various vendors (e.g. Aperio, Omnyx, Leica). The capabilities of virtual microscopy (e.g. whole slide imaging) are exerting a profound impact in the areas of diagnostics, telecommunication, research, information archiving and retrieval, and education/training. Innovations in digital technology (e.g. 3D pathology real-time quantitative visualization) will continue to transform the practice of pathology well into the 21st century.
