  1. Chapter 18 Quality Control Quality Assurance is a JCAHO required 10 step PEOPLE process Quality Control Is an imaging instrumentation and equipment process

  2. QC – 3 step process • Acceptance testing • Routine performance monitoring • Maintenance

  3. Radiography QC • Filtration - Annually • Collimation – Semiannually (+/- 2% SID) • F.S. size – Annually (+/- 50%) FREQUENTLY MISSED PARAMETER! • kVp calibration – Annually ( +/- 10%) • Exp. Timer accuracy – Annually (based on ms used – more leeway with longer exposures) • Linearity – Annually (+/- 10%) of same mAs with differing mA/times • Exp. Reproducibility – Same contr./Dens., etc when exposures are repeated later on

  4. Focal Spot Size Check Tools • Pin hole camera (somewhat hard to use) • Star pattern (down to .3 mm sizes) • Slit camera – preferred method

  5. Other RAD QC • Filtration • Collimation (PBL) • kVp/Timer • Exposure Linearity (same mAs with varied mA and times) • Intensifying screens • Protective apparel • Film illuminators

  6. Fluoro QC • Exposure rate • Spot-fil Exposures • Automatic Exposure System (ABS – AEC)

  7. Tomo QC • Tube travel/ARC • Fulcrum level • Pt. Exposure

  8. Processor QC • See table 18-8 (p. 313) for QC for RAD Processor items/intervals • Processor Maintenance • Scheduled maintenance • Preventative maintenance • Nonscheduled maintenance

  9. Processor Monitoring • Temperatures • Replenishment • Sensitometry/Densitometry
