• Research, Experience and Advice This
  presentation, made by Baltimore VA radiologist
  Eliot Siegel, M.D. at the UK Radiological
  Congress, details the facility's experience
  renovating the reading room. Dr. Siegel explains
  the research that preceded the design and
  continues today in what has become an ergonomics
  research laboratory. (PPT file)

General issues inRSNA online presentations

• Noise, acoustics and voice recognition
• Temperature and other environmental control
  issues
• Improper ergonomics results in
• Eye strain
• Fatigue
• Low back pain
• Occupational repetitive stress disorders

5
Pearls from RSNA / Baltimore VA
Sources of fatigue

• Low monitor brightness
• Monitor flicker
• High ambient light and glare
• Small cursor size
• Need for image manipulation
• Optical issues
• Less fatigue with increased distance
• 25 or greater considered optimal (link)

6
Pearls from RSNA / Baltimore VA

• Number of monitors
• 2 is new paradigm (1 least, 4 most efficient)
• Ambient light - as this increases
• Reading rate decreases
• Accuracy of reading - decreases
• Reader fatigue - increases
• Solution Balance monitor and ambient light

increased need for windowing images
7
Pearls from Baltimore VA

• No significant difference between LCD and CRT at
  100 ft lamberts for pulmonary nodules
• Reduce eye fatigue 20/20/20 Rule
• Every 20 minutes
• look 20 feet away
• for 20 seconds

8
Eliminate glare

• Ambient light keep in balance with monitor
  brightness
• Surface colors, including clothing
• Reduce glare
• Adjust display settings in windows

9
Lack of Integration of Information Systems

• Currently information systems such as the
  dictation system, PACS workstation, and
  electronic medical record (including e-mail,
  Internet and Office Suite), phone are separate
  units

10
Integration Solution

• Would like to see all of these functions
  integrated into a single computer workstation
• Will require vendor with open system support for
  multiple additional computer systems

11
System Integration

• Who else, but the VA !
