Diagnostic Monitor Technology
Medical imaging display monitors are becoming increasingly important. In addition to delivering precise, stable image displays, the demands for monitors now include unified image display between multiple monitors, management of a huge volume of information, and common access to in-house data.
Why are Medical-grade monitors so expensive?
Well, medical grade monitors are required to display images properly and consistently. DICOM Part 14 is used as a standard to adjust the grayscale tone characteristics of monitors. Todays Digital Imaging receptors collect so much information, specific monitor technology is required to view every aspect of what's collected. When DICOM Part 14 medical images are displayed on non-medical grade monitors, the monitor may not offer refined rendering of subtle shadings, unified display between monitors, or rendering consistency over time. Medical-grade monitors are adjusted at the factory to the DICOM Part 14 standard, and are calibration-compliant with DICOM Part 14 to ensure continuing monitor quality control.
When choosing monitors for your facility, it’s important to consider the “Information Volume” of the medical images that the monitor needs to display. For example, a 1MP (Mega Pixel) monitor can display 4 slices from a CT with an image matrix of 512x512 pixels, a 2MP monitor can display 6 slices, a 3MP monitor can display 12 slices without losing any of the information.
A digital Chest X-ray with an image matrix of 1760 x 2150 pixels can only be displayed partially with a 1 or 2MP monitor. To display the full image at once on the screen, a 3MP monitor or better is needed. Choose from lower-resolution 2MP (Mega Pixel) color LCD monitors for basic clinical review use, up to high-resolution grayscale 5MP Mammography-specific LCD monitors and larger.
The bit depth rating of a monitor/adapter combination is also a consideration. Depending on the application, medical monitors can be configured with the following bit depths:
8 bit (monochrome = 256 simultaneous tones, color = 16.8 million color tones)
10 bit (monochrome = 1,024 simultaneous tones, color = 1.07 billion color tones)
A full line of monitor accessories are available ranging from Quality Control kits, remote management software, and wall mount kits.
