They are linked to the digital file but don’t change the integrity of the source image itself.Īnalog telepathology can be considered the predecessor of modern whole slide imaging systems, involving the live remote control of a microscope. These annotations can be side remarks about the case or specific notations on the image itself, highlighting a specific area for example. A digitized field makes it possible to expand workflow capacity and speed up second opinions, because they can be done remotely and slides don’t need to be shipped physically for consultations.ĭigital files also make digital annotations possible, which can be shown or hidden at the pathologist’s will. With digital slides accessible online, slide handling and archiving offer many possibilities, almost all of which contribute to faster turnaround times and more efficient workflows. Laws vary across regions for how long this data needs to stay available.Įven though online storage of large quantities of digital slides brings along its own cost, gathering big data makes deep learning and the use of algorithms possible, the use of which can lead to better insights into specific diseases. Just like the physical slide is stored in a dedicated space, digital files need to be stored in an information management system or vendor neutral archive. Once a pathologist is done with a case, the specimen needs to be stored or archived. Needless to say, it’s important that this device is reliable and shows the slide in an optimal and consistent way. Just like a microscope, the display is the device through which the pathologist views a specimen. These are full systems, Barco offers a stand-alone display that can be used for primary diagnosis. They can use the display as a tool next to their microscope, but the market also offers whole slide imaging systems that were designed for digital pathology and received regulatory clearance to be used for primary diagnosis. Using the viewing software, the whole slide image can be brought up on a display for analysis by the pathologist. After that, the digital slide can be viewed on a display. The resulting digital, high-resolution files can be up to 10 gigapixels in size.Īfter the file has been created, specialized software often compresses the image so it has an optimal size for viewing and analysis. There are scanners in many shapes and sizes, able to scan from 1 to 1,000 slides at a time. Glass slides containing a specimen are converted into digital files by a specialized scanner. A digital pathology environment consists of a number of devices and tools that make it possible to digitize and view a specimen.
