CT Scanner Calibration

Precision Imaging Starts with Precision Calibration

If your GE CT scanner isn’t calibrated correctly, it’s not just a technical issue—it’s a clinical risk. FDM Enterprises provides expert CT calibration services to ensure your scanner is producing accurate imaging checking Hounsfield Units, and artifact-free slices.

Proper calibration restores image quality, boosts diagnostic confidence, and keeps you compliant with ACR and physicist guidelines.

What We Calibrate on GE CT Scanner Calibration Systems

Hounsfield Unit accuracy using water phantoms

Detector gain, offset, and uniformity

Gantry alignment and slice thickness

Table travel accuracy

Air calibration and baseline noise levels

Our CT Scanner Calibration Process

1. Phantom Imaging & HU Baseline Testing

We scan water and air phantoms to measure accuracy and uniformity.

2. Detector Calibration

We run OEM routines to adjust offset and gain across all modules.

3. Geometric Checks

We verify slice thickness, table index, and scan alignment.

4. Post-Calibration QA

We review and document resolution, noise, and HU scale—ready for physicist checks.

Frequently asked questions

What is CT scanner calibration?

CT scanner calibration involves adjusting the calculated uniformity to ensure it produces accurate images, with proper Hounsfield Unit readings, uniformity, and alignment.

Why is CT scanner calibration important?

Calibration is crucial to eliminate imaging artifacts, maintain diagnostic accuracy, and ensure compliance with ACR and physicist guidelines for reliable patient care.

How does FDM Enterprises calibrate GE CT scanners?

FDM Enterprises uses water phantoms for Hounsfield Unit accuracy, checks detector modules to ensure they are in manufacture specifications, tube alignment, and performs post-calibration QA to meet industry standards.

What happens if my GE CT scanner isn’t calibrated correctly?

If not calibrated properly, a CT scanner can distort tissue density, leading to misdiagnosis, repeated scans, and image artifacts, affecting both clinical and diagnostic accuracy.

Why is post-calibration QA important for CT scanners?

Post-calibration QA ensures that the scanner’s resolution, noise levels, and HU scale are accurate and ready for physicist checks, maintaining imaging quality and regulatory compliance.

How often should CT scanners be calibrated?

CT scanners should be calibrated after tube changes, major repairs, or as part of routine preventive maintenance to ensure consistent image quality and compliance with ACR and physicist guidelines.
