What is Inline CT?

Inline CT is the automated CT inspection integrated directly into the production flow. The method delivers actionable quality data for product release, process optimisation and root-cause analysis.

Scientific background

Methodologically, the procedure relies on standardised workflows covering data acquisition, segmentation, feature extraction and evaluation. Core elements include cycle-time optimisation, automatic classification and process feedback. Meaningful results only emerge from traceable criteria and defined acceptance limits.

Relevant key metrics

Detection limit and misclassification risk for the relevant failure modes.
Repeatability of the evaluation for identical input data.
Relationship between indicators and functional load zones / specifications.

Standards and thresholds

Standards: ISO 15708-3:2025 as well as IATF 16949:2016 combined with ISO 9001:2015.
Typical thresholds (in practice): Inspection time ≤ line takt; false-accept (slip-through) and false-reject rates are limited to customer-specific targets (e.g. below 1–2 %).
Validity: Takt and decision limits depend on product mix, risk and escalation strategy.

Application in industrial practice

Data-based release decisions during ramp-up and series production.
Early detection of deviations with cause-oriented prioritisation.
Improved customer and supplier communication through objective CT reports.
