Components of CT Image Quality QA Testing Service
- Image Noise Analysis: Quantifying random variations in pixel values, which can obscure subtle anatomical details. This involves using phantoms with homogeneous materials to measure noise levels across different regions of the image.
- Spatial Resolution Assessment: Evaluating the ability of the CT system to differentiate between closely spaced objects. This is typically assessed using bar pattern phantoms or point source phantoms and measured in line pairs per millimeter (lp/mm) or modulation transfer function (MTF) analysis.
- Low-Contrast Detectability (LCD) Evaluation: Determining the system's capability to visualize objects with subtle density differences compared to their background. This is crucial for detecting soft tissue lesions and is often assessed using phantoms with low-contrast inserts of varying sizes and contrast levels.
- Geometric Accuracy Verification: Confirming that the spatial relationships and dimensions of anatomical structures are accurately represented in the CT images. This involves measuring distances and angles on phantom images and comparing them to known values.
- Artifact Identification and Characterization: Detecting and quantifying image artifacts (e.g., beam hardening, metal artifacts, motion artifacts) that can degrade image quality and lead to misinterpretations. Analysis involves identifying common artifact types and their impact on diagnostic content.
- Slice Thickness Uniformity: Ensuring that the physical thickness of each reconstructed CT slice is consistent across the field of view.
- Image Uniformity and Artifacts: Assessing the consistency of signal intensity across homogeneous regions and identifying any systematic image distortions or anomalies.
- Dose Monitoring and Optimization: While not directly image quality, ensuring that radiation dose is optimized to achieve acceptable image quality is a critical component of a comprehensive QA program. This involves measuring patient dose and comparing it to diagnostic reference levels (DRLs).
- System Performance Trending: Establishing baseline performance metrics and monitoring these parameters over time to detect gradual degradation in image quality or system malfunction.
- Image Acquisition Protocol Review: Evaluating the appropriateness and optimization of CT acquisition protocols for specific clinical applications, ensuring that parameters like kVp, mAs, pitch, and reconstruction algorithms are optimally configured.
- Image Display and Viewing Conditions: Verifying that images are displayed on calibrated monitors under appropriate ambient lighting conditions to facilitate accurate interpretation.
