History of Digital Pathology
In the Middle East during the Islamic Golden Age and inWestern Europe during the Italian Renaissance, the scientific method was first used to the study of medicine. This development can be linked to the history of pathology.
Early in the third century BC, the Greek doctors Herophilus of Chalcedon and Erasistratus of Chios performed the first systematic human dissections.
The Arabian doctor Avenzoar (1091–1161) is
recognised as the first medical professional to do postmortem dissections. Most
people agree that Rudolf Virchow (1821–1902) is credited with founding
microscopic pathology. The majority of the first pathologists were also working
doctors or surgeons. Also consider Egyptian mummification as an example of
early embalming and post-mortem organ removal, as shown by premodern necropsy.
Digital pathology has its origins in the early telepathology investigations that were conducted in the 1960s. The concept of virtual microscopy first surfaced in numerous fields of life science research later in the 1990s. The phrase "digital pathology" came to be used by the scientific community at the turn of the century to describe pathology digitalization activities. The technical requirements (scanner, storage, and network) were still a constraint for a widespread adoption of digital pathology principles in 2000, though.
This altered over the past five years when
new, powerful, and reasonably priced scanner and mass/cloud storage
technologies entered the market. There are significant distinctions between
digital images used in radiology and digital pathology, which is why the
discipline of radiology underwent a digital transformation approximately 15
years ago rather than because radiology is more advanced. The (living) patient
is the picture source in radiography, and currently, the image is often taken
mostly in digital format. In pathology, specimens that have been conserved and
processed are scanned, and for retrospective research, slides that have been
kept in a biobank are also used.
In addition to the pre-analytics and metadata content differences, digital pathology requires two to three orders of magnitude more storage than radiography does. The benefits of digital pathology, however, are comparable to those of radiography.
Today, telepathology, teleconsultation, research endeavours, and instructional reasons are all common uses of digital pathology. The ability to download annotated lecture sets creates new options for e-learning and knowledge exchange in pathology. Digital pathology makes it much easier to distribute and annotate slides. A new and developing field in diagnosis is digital pathology.
