Medical professionals use monitors during diagnosis, surgery, and treatment. For accurate and consistent performance, they need medical-grade monitors, as inferior technology or erroneous calibration can have serious consequences.
A large number of monitors, from consumer-grade to high-end medical-grade monitors, are available in the market. However, not all of them can provide the quality of medical images needed for diagnosis.
Image Quality and Medical-Grade Monitors
A monitor’s operational characteristics can influence image quality, thereby affecting their performance. Clinicians prefer medical-grade LCD monitors that are compatible with digital imaging and communications in medicine (DICOM) standards for handling, storing, and transmitting medical image information.
Medical-grade monitors have the following characteristics that enhance image quality.
More colors, more accuracy: Ability todisplay more colors, which allows medical imaging professionals to use precise coloration judgments during medical procedures or diagnoses. Nearly all workstation displays now use LCD or organic light-emitting diode (OLED) panels.
Better luminance: Automated backlighting systems and closed-loop control circuits to maintain stable peak luminance as soon as they are switched on.
The majority of medical-grade monitors today are liquid crystal displays (LCDs) with LED backlighting.Theycontinuously approximate desired peak luminance, ensuring consistency. Better luminance means more just noticeable differences (JNDs) and a wider grayscale spectrum, which makes detecting even minute lesions faster.
Image consistency: Consistent image brightness and clarity throughout their life spans. By automating all related systems, medical-grade monitors can ensure that the image quality is the same on all other medical-grade monitors connected to the network.
Adjustability: Bigger medical screens help radiologists view images in full on a single screen, without panning or zooming. They also have scale-to-fit capability, which makes reading easier. Medical-grade LCD monitors are perfectly flat, less heavy, thinner, and more adjustable.
Reliability: Most medical-grade monitors automate quality assurance and remote calibration to guarantee 24/7 service and compliance with medical standards. This makes them reliable and easy to integrate into various types of workstations and with other medical-grade solutions.
Multi-modality: Many medical displays allow viewing of multiple modalities—both color and grayscale—on a single screen. They also enable speedy side-by-side comparisons and image fusions, without switching displays.
Reduced expenses: All the other advantages do not imply costly equipment. Medical-grade monitors are designed to work with almost all medical workstations. This means that hospitals need not invest in additional equipment/software. They can save further by consolidating and standardizing displays.
Such monitors have long warranty periods and guarantee consistent compliance with medical standards, which means lesser servicing, support and infrastructure costs.
Types of Medical-Grade Monitors
Different medical-grade monitors are used for different purposes.
Surgical grade: Surgeons usethese monitors to view movements of instruments and the state of tissues during surgery. These monitors have fast response times and great readability at extreme viewing angles.
They have mandatory antimicrobial coating, needed in sterile operation theaters, and are able to withstand accidental medication or blood spills and chemical disinfectants. They support multiple video modes and dual-screen mode and have many ports to connect other devices.
Diagnostic grade: Radiologists need the best color reproduction and contrast, along with DICOM certification. They must have excellent image uniformity and high brightness.
Medical touchscreen monitor: Many medical professionals use their primary medical-grade LCD monitors to interpret images for billing and reports. They also need accurate, medical-grade touchscreens as secondary monitors for patient edutainment, review by surgeons, quality assurance, etc.
Touchscreens eliminate the need for peripherals, thereby limiting wire clutter and ensuring patient safety. Although DICOM certification isn’t necessary, they should have anti-glare and antimicrobial coating and the capability to withstand liquid disinfectants.
Medical-grade monitors are needed at hospitals because they last longer and give assured quality and accuracy to medical images. This makes them valuable to healthcare practitioners and patients.
