Summary Slide
• Practical Design Features for a PACS Radiology Department
Practical Design Features for a PACS Radiology Department
Stephen G Davies
Royal Glamorgan Hospital
Overview
• Radiologist office / reporting areas
• Radiographer zone / image processing
• Computer room
Radiologist office
• Primary function is image viewing
• Workstation– ergonomics
• Desking– Height, size and cabling
• Environment– Light, heat and noise
Ergonomics
• Ergos = Work
• Nomos = Laws
• Workplace design taking into account the needs of an individual
• Consider tasks to be performed and the manner in which the individual will perform them
Why?
• We spend a lot of effort in the technical specification of PACS – we must also spend time on ergonomics– Diagnostic accuracy of
reporting
– Health of radiologist/radiographer
Key areas
• Environmental lighting and its effect on image perception
• Avoidance of repetitive strain injury– Body posture– Repetitive movements– Desking; mousing and keyboard
Environmental lighting
• Visual perception influenced by– Spatial and contrast resolution of display– Brightness (luminance) of the display– Extraneous lighting in reporting room
Brightness of image display
• Contrast sensitivity of the human eye increases as the object luminance increases
• Perceived image quality also increases with increasing image luminance, until glare has a negative effect
• But PACS monitors have lower levels of luminance
• Other factors become more important– Masking of image surrounds– Extraneous light
Extraneous light
• Contrast good for display; bad for reflection
• Ambient lighting– Low level– Suspended uplighting– Supplemented by task
lighting
• Extraneous light– Window; corridor
Desk requirements
• Monitor footprint• Separate RIS
monitor• Cable tray • Mouse and keyboard
position• Paperwork• Task lighting
Desk and Chair
• Optimum body posture – not ideal posture
• Desk and chair height for– Mouse and keyboard– Monitor– Spine
Reporting room layout
• Two and four station• Lighting• Noise• Heat
Radiographer zone:Image processing
• Space
• Workflow (CR+DR)
• Environment– Light– Heat
• Power and network points
• Back up systems
Computer Room• Equipment
– Archive/ RAID– Servers - Clinics, Wards, Teleradiology– Servers - RIS and Dictation
• Access to equipment
• Cooling
• Room for expansion
• Security
• Disaster: fire, flood, etc
