PACS displays: how to select the right display technology

Area of Science:

• Medical Imaging Technology
• Diagnostic Display Systems
• Clinical Visualization

Background:

• Medical imaging displays are specialized instruments with unique features crucial for clinical applications.
• Commercial-grade displays lack the necessary precision and features for medical imaging.
• Understanding these features is vital for informed purchasing decisions.

Purpose of the Study:

• To elucidate the critical features and clinical value of medical imaging displays.
• To guide healthcare professionals in making informed purchasing decisions for diagnostic displays.
• To emphasize the importance of performance testing and calibration for medical imaging displays.

Main Methods:

• Analysis of key performance indicators for medical imaging displays.
• Evaluation of display characteristics such as brightness, pixel size, and display size.
• Consideration of viewing distance in relation to display specifications.
• Review of calibration conformance checks and their significance.

Main Results:

• Consistent display brightness (approx. 400 cd/m²) and DICOM curve conformance are essential for effective performance checks.
• Display resolution (megapixels) is a less critical determinant of image quality compared to pixel and overall display size.
• Optimal display selection depends on viewing distance, balancing pixel density and screen real estate for visual information intake.

Conclusions:

• Informed selection of medical imaging displays hinges on understanding specific features and their clinical relevance.
• Routine performance testing and calibration are necessary for maintaining display integrity and diagnostic accuracy.
• Matching display size and pixel characteristics to viewing distance ensures optimal visualization of clinical information.
