Medical Grade display systems offers best of radiologist's viewing experience.For each modality and method of use, the correct display monitor needs to be deployed.
Viewing station or monitor display system play an important role in modern radiology practice. As right choice of display system can have a paradigm shift on the image quality and the resultant diagnosis, technical knowledge is useful when deciding to go display systems.
Sometimes, medical grade monitors are ignored for cost optimization in the radiology department. The technical knowledge will assist in choosing the right monitor for the department for better reporting and treatment plan.
Monitor displays are an integral part of today's radiology work environment, attached to workstations, USG, CT/MRI consoles and PACS terminals. Various performance parameters in a medical grade monitor include:
- medical grade monitor's resolution ranges from 1MP to 9MP and higher as compared to commonly available computer monitors with resolutions of 640X480, 800X600, or 1024X768. Higher resolution ensures better image quality.
- Aspect ratio of 16:9 and, occasionally, even 16:10 or 15:9 is preferable
- A 17X14 image is optimally viewed in the portrait mode which is particularly useful for chest and skeletal radiography and for mammography.
- Medical displays systems offer up to 4096 shades of gray (12 bit) as compared to 256 (8bit) in a consumer displays system.
- An optimal grayscale response for monitors can be achieved by calibration of monitors.WIDE display systems have auto-calibration technology.
- Knowledge of color bit depth is useful when working with color Doppler as well as CT scan, and MRI images, where color-encoded functional imaging is displayed on color monitors.
- Medical-grade displays are also designed to provide very high luminance. Compared to consumer-grade displays, WIDE displayssystemshave a much higher luminance range: more than 1000 cd/m2 compared to 250–300 cd/m2 for consumer-grade displays.The higher luminance offered by medical displays results in better image quality, making subtle lesions easier to detect.
