Image Quality Audit

Image Quality Audit Skill

Triggers

• "image quality audit"
• "artifact review"
• "dose analysis"
• "protocol deviation"
• "quality metrics"
• "diagnostic adequacy"
• "technique optimization"

Parameters

• audit_type (required): Type of quality assessment
  • artifact - Motion, noise, streak artifacts
  • dose - Radiation dose optimization and DRL compliance
  • protocol - Protocol adherence and deviation analysis
  • adequacy - Diagnostic sufficiency for intended purpose
  • technique - Technical parameters review
  • comprehensive - Full quality review
• modality (required): Imaging modality to audit
• time_range (optional): Audit period - defaults to last 7 days
• sample_size (optional): Studies to review - defaults to all in range
• severity_threshold (optional): Minimum severity to flag

Evaluation Criteria

• Artifacts: Type, severity (1-5), impact on diagnostic utility
• Dose: DLP, CTDIvol vs. ACR reference levels, size-adjusted metrics
• Protocol: Coverage completeness, sequence selection, contrast timing
• Adequacy: Signal-to-noise, spatial resolution, positioning

Output Format

Returns structured JSON with:

• Quality metrics summary
• Severity distribution
• Contributing factors analysis
• Improvement recommendations ranked by impact
• Training priorities for technologist/site issues

Usage Examples

audit_type: artifact
modality: CT
time_range: last_week
severity_threshold: 3

audit_type: dose
modality: CT
time_range: last_month

Standards Reference

• ACR Physical Parameters for CT, MRI, Ultrasound, Mammography
• ICRP and ACR dose reference levels
• modality-specific practice guidelines
