Fitting Monitor Solutions

Selecting the right monitor for your needs doesn't have to be complicated - with a bit of consulting.

Legal requirements and common standards are a good guide for finding the right solution.

Long-term warranties by the manufacturor and the availability of necessary functions of the device are the best way for finding a device meeting your quality needs.

Since the 1st of March 2015, a new standard - DIN 6868 - 157, has been ratified. For serious distributors, this should not lead to problems.

 

To cut a long story short: A safe diagnosis for the radiologist and a good investment for your business, these are the requirement we have to meet.

 

Important requirements for Diagnostic Monitors and Clinical Review Monitors

Grayscales

 

Since DIN 6868-157 is being enforced, so now the control of the DICOM-Curve is a legal duty. The human eye is capable to capture a spectrum of approximately 1000 grayscales. Especially when doing diagnosis of fine structures (e.g. when it comes to lung tissue or mammography), a sophisticated grayscale-technology comes along with a lot of advantages. The combination of the Monitor, the medical graphics card and software must be at the same "grayscale-level". If 10-bit grayscales are nut supported by one of those items, you will only be able to see a quarter (256) of the available grayscales (1024).

Luminosity and room brightness

Diagnostic Monitors at least need to have a luminosity of 200cd/m² - and this luminosity has to last for years. The room brightness has to be analysed according to the room class which is needed. The brighter the room is, the higher the requirements are for your medical monitor. Our reccomendation is to use monitors with LED Backlight - technology which leads to longer life times of the device and a constant brightness - so it is a good investment - as well for your diagnosis as for your wallet.

Integrated ambient light sensors, which are adjusting the monitor brightness live according to the changed brightness in the room, are more than useful.

Contrasts

For detecting even smallest and finest structures, very high contrast ratios are necessary. The better differentiating between black levels makes a sharper displaying of grayscale pictures possible.

Homogenity

Color/Grayscale homogenity is needed, to avoid wrong interpretations of the image. Technically, this is a little bit more difficult since LCD screens are hindering due to their constuction. The important it is to check, if the monitors is equipped with fitting software solutions (e.g. uniformity equalizer), compensating this lack of homogeneity.

Medical Graphic Card

Medical graphic cards ensure, that the diagnostic software (e.g. PergamonVIEW) can send it's signal in the right way to the diagnostic monitor. Especially the use of 10-bit grayscales is necessary here.

Also special graphic technologies, which are mainly implemented for common office tasks or gaming, have to be disabled when it comes to diagnosis (e.g. Anti-Aliasing, Dithering) because it could manipulate the picture.

Since DIN-6868-157 is active, the use of medical graphic cards is mandantory.

Legal Issues

Basically, the manufacturer declares application classes and certifications and declares, for which appications the monitor is suitable. Always be aware of the manufacturers intended use and don't act against it, because only for intended use the manufacturer takes responsibility.
