exposure at skin entrance
Exposure at Skin Entrance
  • Measure common radiographic projections during regulatory inspection:
    • Common patient thicknesses
    • Measured with MDH X-Ray Monitor
    • Monthly workloads collected

CRCPD 38th Annual Conference - Detroit

  • Exposure data entered into Radiation Safety Data System
    • Recent update distinguishes between digital modes Computed Radiography (CR) and Direct Radiography (DR)

standard of care exposure values
Standard of Care Exposure Values
  • Established by advisory committee near the 85th percentile of ESE data
    • Last adjustment in 1995
    • Mostly based on 200 speed screen-film
  • Non-regulatory

exposures reported to facility
Exposures Reported to Facility
  • Measured Entrance at Skin Exposure along with the Standard of Care for that projection
  • Advised to reduce exposure if over the Standard of Care
  • Good cooperation from facilities in reducing exposures when appropriate

exposure distribution graphs
Exposure Distribution Graphs
  • Most recent 5 year period
  • Screen-film and digital imaging displayed separately
  • Number of machines tested, median exposure, and 85th percentile data included

CRCPD 38th Annual Conference - Detroit

exposure trends
Exposure Trends
  • The difference between the 85th percentile and the median exposure is being reduced
  • “Outriders” are being becoming less of a problem

standard of care conclusions
Standard of Care Conclusions
  • Standard of Care values or reference values are effective in controlling exposures
  • They do not adversely drive exposures below what is necessary for diagnostic quality images
