To encourage the development, exchange, or sharing of information, including data and photographs, digital pathology is the application of information technology to the area of pathology. The primary goal is to simplify the intricate workflow for anatomical pathology from specimen receipt to report transmission (AP).
AP information systems and digital
image analysis systems, including image gathering and processing, are the
two fundamental elements of digital pathology. Digital
pathology, however, accomplishes more than just link scanners
to AP data systems. In order to process and model the huge quantity of data
included in WSIs, image analysis methods must be developed. This will enable
collaboration between many departments and health care systems, which will
benefit pathologists throughout their work.
Pathology utilizes technology
The biggest strides in pathology
have been made through the application of genomic-based molecular
techniques, including polymerase chain reaction (PCR), fluorescence in situ
hybridization (FISH), array comparative genomic hybridization (aCGH), and more
recently DNA sequencing.
All of these methods allow for the identification of
chromosomal aberrations that are locus specific or imbalanced, contain a net
gain or loss of genetic material, and are associated with a specific disease
state. Each makes a contribution to the particular apps used by pathologists.
As the gold standard for finding and diagnosing
cancer, pathologists still utilise microscopes. This makes sense for a
number of reasons. Typically, pathologists do not rely on empirical data when
making their diagnoses. By examining a well-stained slide by itself and
changing the focal planes on the optical apparatus, they can determine from
experience the likelihood that a sample is aberrant. To the extent where, in
some circumstances, they are able to inform the referring physician of the
treatment the patient is likely to respond to, pathologists have welcomed more
tests to help in fully defining a patient's illness.

The localization of many protein and related species
antibodies in a single segment from the same source is known as multiplexing.
The simultaneous interaction of vital proteins with various cell compartments
or cell types is made easier by multiplexing. All of a cell's attributes can be
measured at once. Through the application of new multiplexing methods,
automated multispectral slide imaging tools, and new protein expression technologies,
novel investigations in digital
pathology are emerging. The primary focus of modern oncological
examinations is on immunohistochemistry (IHC) procedures and multispectral
analysis with the aforementioned
image processing and pattern recognition tools. To assess the usefulness of
this innovative multiplex IHC approach, the expression profiles of each marker
were looked at.
The integration of WSI and digital pathology
technologies holds the potential to improve image integration in
information systems, balance workloads, and streamline workflow. The
integration of all the data that can be retrieved from a tissue sample using
advanced, automated, and miniaturised technologies will be aided by strong
computer-based algorithms.
The use of standards and the creation and validation of
image analysis tools are the two key factors driving the adoption of digital
pathology in clinical practise.
