Frequently Asked Questions
Most manufacturers recommend CT scanner calibration at least annually, though high-volume facilities may benefit from semi-annual calibration. Additionally, calibration should be performed after any major service, tube replacement, or software update. FDM Enterprises can help you establish the right calibration schedule for your facility's needs.
Post-calibration quality assurance verifies that all adjustments were successful and the scanner is performing within acceptable parameters. FDM provides a detailed QA report after every calibration, giving you documentatio
An improperly calibrated CT scanner can produce inaccurate Hounsfield Unit values, leading to incorrect density measurements. This can affect diagnosis accuracy, cause image artifacts, result in incorrect radiation dose delivery, and potentially lead to regulatory compliance issues during inspections.
CT scanner calibration is the process of adjusting and verifying a CT scanner's imaging parameters to ensure it produces accurate, consistent diagnostic images. This includes verifying Hounsfield Unit accuracy, adjusting detector alignment, and confirming dose output levels meet manufacturer specifications.
Proper calibration ensures your CT scanner delivers accurate diagnostic images, maintains patient safety through correct radiation dose levels, and meets regulatory compliance requirements. Without regular calibration, image quality can degrade, potentially leading to misdiagnosis or unnecessary radiation exposure.
Our calibration process includes phantom imaging and HU baseline testing, detector calibration and alignment verification, tube output and dose verification, image quality assessment across all scan protocols, and a comprehensive post-calibration QA report documenting all results.
