Regular-grade displays are designed for use in our daily lives and standard office environments, in other words, for activities that do not require the best visual capabilities and high levels of detail.
Medical monitors are specifically designed for diagnostic and clinical needs and their advantages are obvious compared to conventional office displays. They provide accuracy, consistency and high image quality, which is important for diagnostic accuracy. Let's look at the key advantages of medical monitors.
The job of medical professionals, particularly radiologists, is to be able to detect tiny details that go unnoticed on regular office monitors. Accurate interpretation of these details is key to the further progress of the diagnosis. Errors in interpretation can lead to a false diagnosis and serious consequences for the patient's health. Office monitors do not provide the required accuracy and detail for medical tasks. Medical monitors guarantee high image quality, which is critical for accurate diagnosis and effective treatment.
2. Wide range of colors
Medical monitors are capable of displaying up to 1 billion colors, compared to 16 million in typical office displays. With the development of technology, this difference is sure to become even greater. This wide range of colors allows even the smallest gradations to be accurately reproduced, which is critical for medical image analysis, particularly in areas such as MRI, CT and ultrasound. Thanks to this, doctors can more accurately identify pathological changes, which improves the quality of diagnosis.
3. High resolution
Medical monitors are classified by resolution (in megapixels, MP): 2MP, 3MP, 5MP and higher:
2MP (1920x1200 or 1600x1200 pixels) – suitable for general visualization.
3MP (2048x1536 pixels) – often used for CT and MRI.
5MP (2560x2048 pixels) - optimal for mammography, where maximum detail is important.
8MP (3840 x 2160 pixels), 12MP (4200x2800 pixels) – provide multimodal visualization on one screen.
This high resolution eliminates the need to zoom or pan the image, saving time and reducing eye strain for clinicians.
4. Brightness
Medical monitors provide brightness in the range from 600 to 3000 cd/m2, which is several times higher than that of office monitors (usually about 300 cd/m2). High brightness is critical for accurately recognizing image detail, especially in bright lighting conditions. In addition, medical monitors maintain brightness stability throughout their entire lifespan, ensuring consistently high visual quality.
5. Contrast
The contrast ratio of medical monitors reaches 2000:1, which is critical for accurately identifying anomalies and working with shades of gray. This high level of contrast makes it possible to clearly distinguish even the smallest details in medical images, which is especially important for diagnostic radiology, mammography and CT. In comparison, office monitors have a contrast ratio of only 500:1–700:1, which significantly limits their use for medical purposes.
6. Image uniformity
Medical monitors provide uniform brightness and accurate color reproduction across the entire screen area (LUT technology). This guarantees high image quality regardless of their location, which is a key factor for accurate diagnosis. These monitors are available in two versions:
Monochrome monitors provide higher contrast and grayscale detail. This makes them ideal for mammography and radiography, where clarity of the smallest details is critical.
Color monitors are used for multimodal examinations such as CT, MRI and ultrasound, where a wide range of colors helps accurately analyze medical images.
The choice between a monochrome and color monitor depends on the specifics of the research, but both options provide image uniformity, which is a necessary condition for high-quality diagnostics.
Medical monitors are equipped with sensors that ensure image stability and accuracy:
Front sensor: Provides auto-calibration of brightness and color according to DICOM standards.
Ambient Light Sensor: Compensates for changes in ambient light levels for optimal visualization.
Human Presence Sensor: Puts the monitor into power saving mode when the user is away and automatically turns on when returning.
Conventional monitors do not have integrated sensors, especially the front sensor for auto-brightness calibration. In addition, their brightness decreases by 30% after the first year of use and can drop by up to 50% during the second year. This creates uncertainty about the authenticity of the image displayed on a regular monitor.
8. Compliance with medical standards
Conventional office monitors do not meet the DICOM (Digital Imaging and Communications in Medicine) medical standard for brightness and contrast. They are not equipped with the necessary tools to properly view medical images, leaving users in the medical environment to manually calibrate monitors and frequently check their status. This may cause important details to be lost in images.
Medical monitors are automatically calibrated to the DICOM standard thanks to built-in sensors, ensuring accurate and stable images. Additionally, these monitors can store and track calibration measurements throughout their lifetime, ensuring long-term accuracy and reliability.
9. Durability and long warranty period from the manufacturer
Medical monitors have a much longer lifespan than office displays. Typically, these monitors come with a warranty of up to 5 years, which ensures that key parameters such as brightness, contrast and image uniformity are maintained throughout their lifespan.
JVC is the world's leading medical monitor market with 50 years of experience. The Japanese company, known for its innovative solutions, is constantly improving the technologies introduced into medical monitors to meet the needs of modern medicine. Some of them:
Unique Dynamic Gamma technology automatically analyzes each pixel of the image, determining its type and displaying it in optimal quality. If the image is monochrome (black and white - X-ray, mammography, B-mode ultrasound, CT, MRI), it is displayed with DICOM calibration, which ensures accurate grayscale reproduction. If the image is in color (pathology, histology, CT or MRI reconstruction), Gamma 2.2 calibration is used - the optimal standard for transmitting color images.
The patented ISD - Independent Sub Pixel Drive feature uses a unique approach to pixel construction. Each pixel consists of three subpixels, which on color monitors correspond to the RGB principle (red, green, blue). With this technology, JVC optimizes the use of subpixels, increasing the monitor resolution by three times. For example, a 3 MP monitor increases its resolution to 9 MP, and a 5 MP monitor to 15 MP, providing extreme detail and clarity in images.
Uniquely designed dual monitor bracket. A special bracket designed to simultaneously accommodate two monitors. Thanks to integration with Daisy Chain technology, the bracket optimizes the working space, ensuring the convenience of the doctor's work. Placing two monitors side by side, especially 5 MP models, greatly improves the ability to visualize the breast. This allows for a 2x5 MP or 10 MP equivalent diagnostic configuration, expanding the potential for accurate image analysis.
Medical monitors are a tool that ensures diagnostic accuracy, durability and compliance with medical standards. They are essential for clinical and diagnostic needs where image quality is critical for diagnosing medical images of different modalities.
