# 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
