Monitors for pathology
The digitalisation of pathology has made it easier to assess the smallest cell and tissue structures, which are now transferred to screens via high-quality opto-electronic microscopes, where they can be viewed in the greatest detail. The monitors must provide an excellent image quality so that even the slightest changes or anomalies can be detected.
Ideal for individual requirements in pathology
EIZO monitors are optimally equipped for this challenge. Not only do they have an excellent screen resolution, but they also display colours with outstanding accuracy. A high (spatial) resolution, a wide gamut, a deep black level, homogeneous illumination, a reproduction curve that can be calibrated according to individual requirements and consistent image reproduction quality guarantee reliable diagnostics, even for the smallest tissue structures.
What is important when choosing a monitor for pathology
The higher the monitor’s resolution, the more details the user will see. Images are less pixelated, have sharper contours, and more content is displayed at one time.
For digital pathology applications, 27-inch to 32-inch widescreen monitors are recommended to fill the user’s natural field of view.
To get the most accurate information out of each image, you need to consider the screen size, resolution, and distance between the monitor and the user at the workstation when selecting a monitor.
Inhomogeneity causes an image to appear differently depending on its position on the screen. This could result in the user having to move the image on the monitor in order to obtain all the information from it. With the DUE (Digital Uniformity Equalizer) function, medical monitors in the RadiForce series can compensate for differences in brightness and colour. As an example, the picture on the left shows a monitor with DUE and on the right a monitor without DUE.
Routine quality control ensures that pathological diagnoses are consistent and reliable. As a result, users trust the information they see on the screen and there is a lower risk of misdiagnosis.
Medical monitors have a much longer service life than standard monitors. This means they can be in heavy use over a long period of time.
Other important points
The Bundesverband Deutscher Pathologen e.V. (National Association of German Pathologists) recommends an image brightness of at least 300 cd/m2 for monitors used in pathology diagnostics. This roughly corresponds to what you would see under a conventional microscope. To maintain a consistent brightness over time, monitors that offer much higher brightness levels are recommended to provide a buffer to allow for the aging of the device and stricter brightness standards in the future.
To ensure high differentiability in dark and bright areas on an image and be able to control homogeneity, a contrast ratio of min. 1000:1 (static contrast ratio) is recommended for a monitor used in pathology diagnostics.
Billions of colours for precise colour gradation
It is important for the work of pathologists that all monitors meet the established colour standards.
Quality control software
Quality control software for medical monitors helps in performing monitor validation tests according to national and international quality standards and in adapting the monitor to the specific working environment.
