What is digital pathology?
Digital pathology is an information environment based on digital images of drugs. Digital pathology is part of virtual microscopy and, in fact, is the conversion of drugs on slides into their high-quality digital copies. Digital copies of drugs can subsequently be used for viewing, analysis, archiving, teleconferencing, external counseling, training, etc.
Digital pathology is currently considered one of the most promising areas in diagnostic medicine. Allows you to reduce the cost, while increasing the speed and quality of diagnosis and prediction of the pathology. Digital pathology is a popular and effective tool for diagnosis, allows you to switch from viewing the required number of fields of view through a microscope to visualizing the entire drug in ultra-high resolution.
Digital Pathology Features
- Viewing a digital copy of the drug in ultra-high resolution;
- Application of morphometric analysis algorithms;
- Creating an archive of digitized drugs with primordial coloring and the ability to add information about the patient, doctor, diagnosis, etc .;
- Getting a second opinion;
- Conducting external counseling online;
- Training on virtual drugs.
Equipment for digital pathology
To create digital copies of the preparations located on the slide, a special device is used - the Digital scanner of micropreparations . All modern micropreparation scanners can be globally divided according to the principle of scanning into two large groups: panning and linear scanning.
- Panning is a traditional way of obtaining images consisting of more than one field of view. The resulting image is formed by software stitching several fields of view. Although modern software allows for very high-quality image processing, nevertheless, cross-linking errors in the form of fragment shifts can often be found on the resulting images of scanned preparations.
- Linear scanning is a more advanced and highly accurate method. Scanning is performed using a linear TDI matrix. Similar matrices are used in mapping and aerial photography. The principle of operation of the scanner, whose operation is based on the linear scanning method, can be understood by imagining a conventional paper scanner: an object is scanned line by line. The resulting image is formed immediately pixel by pixel. The likelihood of errors in processing the final image and incorrect cross-linking is significantly reduced.
