FUNCTIONALITY / TESTING SUMMARY
System Recognition
Probe recognized immediately by Siemens ACUSON Antares system with no communication errors.
System Presets / Applications Observed
Abd‑Difficult, Abdomen, Abdomen‑C, Chest Mark, Fetal Echo, GYN, GYN_C, OB, Prostate, Pelvis, Renal.
Air Scan Evaluation
- Sector formation preserved
- Depth penetration acceptable
- Multiple non‑uniform echogenic bands and mild vertical grayscale irregularities present
- Findings consistent with early element wear rather than complete dropout
- No large black dead zones observed
Uniformity / Phantom‑Style Evaluation
- Faint horizontal reverberation‑type artifacts
- Mild grayscale non‑uniformity in deeper sector
- Sector geometry stable; no severe collapse or major dropout
Body Scan Evaluation (Hepato‑Renal)
- Hepatic and renal structures visualized
- Recognizable anatomy with preserved organ differentiation
- Penetration and grayscale contrast acceptable for basic imaging
Color Doppler Evaluation
- Color flow mapping responsive
- Doppler fill and vascular signal acquisition preserved
Technical Imaging Observations
- Probe recognized consistently
- Sector geometry preserved
- Mild image non‑uniformity present
- Early element wear/artifact suspected
- No major dead element dropout
- Color Doppler functional
- Suitable for basic/general imaging
- Detailed diagnostic performance not formally verified
WHAT IS INCLUDED
Siemens CH4‑1 Convex Ultrasound Probe
WHAT IS NOT INCLUDED
Ultrasound system, phantom, user manual, storage case, additional accessories not shown.
BUYER ADVISORY NOTE
Only basic operational testing was performed. Imaging artifacts and mild non‑uniformity suggest early element aging/degradation. Probe may be suitable for general imaging or training applications but may not be ideal for advanced diagnostic use. Preventive maintenance, calibration, and clinical suitability verification are recommended prior to patient use.
SHIPPING NOTE
Professionally packed and shipped from Medicka Medical, Minnesota.
