4. Operating Instructions
4.1 Setup
Place the phantom centered on the patient table or cassette holder.
Align the phantom’s reference marks with the X‑ray central ray.
Set exposure parameters (kVp, mAs, SID) per your facility’s QA protocol.
4.2 Test Procedures
4.2.1 Spatial Resolution
Expose the high‑resolution line‑pair grid (2–20 LP/mm).
Determine the smallest resolvable line pair (record LP/mm value).
4.2.2 Contrast Sensitivity
Image the low‑contrast bar targets (varying thickness/density).
Identify the thinnest visible bar to assess contrast detection capability.
4.2.3 Uniformity & Artifact Check
Inspect the image for uneven density, noise, or artifacts (e.g., grid lines, scratches).
Verify the phantom’s background is uniformly exposed.
4.2.4 Geometric Accuracy
Measure distances between alignment markers to confirm geometric distortion is within tolerance.
5. Maintenance & Storage
Cleaning: Wipe surface with mild, non‑abrasive disinfectant; avoid harsh chemicals.
Storage: Store in a dry, dust‑free case at room temperature (15–30°C).
Inspection: Check for cracks, scratches, or discoloration quarterly; replace if damaged.
Calibration: Annual recalibration recommended (NVLAP‑accredited lab).
6. Warranty & Support
Warranty: 2‑year limited warranty against defects in materials and workmanship.
