  1. Summary Slide • Practical Design Features for a PACS Radiology Department

  2. Practical Design Features for a PACS Radiology Department Stephen G Davies Royal Glamorgan Hospital

  3. Overview • Radiologist office / reporting areas • Radiographer zone / image processing • Computer room

  4. Radiologist office • Primary function is image viewing • Workstation • ergonomics • Desking • Height, size and cabling • Environment • Light, heat and noise

  5. 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

  6. 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

  7. Key areas • Environmental lighting and its effect on image perception • Avoidance of repetitive strain injury • Body posture • Repetitive movements • Desking; mousing and keyboard

  8. Environmental lighting • Visual perception influenced by • Spatial and contrast resolution of display • Brightness (luminance) of the display • Extraneous lighting in reporting room

  9. 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

  10. Extraneous light • Contrast good for display; bad for reflection • Ambient lighting • Low level • Suspended uplighting • Supplemented by task lighting • Extraneous light • Window; corridor

  11. Desk requirements • Monitor footprint • Separate RIS monitor • Cable tray • Mouse and keyboard position • Paperwork • Task lighting

  12. Optimum body posture – not ideal posture Desk and chair height for Mouse and keyboard Monitor Spine Desk and Chair

  13. Reporting room layout • Two and four station • Lighting • Noise • Heat

  14. Radiographer zone:Image processing • Space • Workflow (CR+DR) • Environment • Light • Heat • Power and network points • Back up systems

  15. 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
