In Professor Hopkins’ previous ptj Insights, the focus was on pipeline defects. In this ptj Insights, we will focus on anomalies. 

The word “anomaly” applies here since we will look at inspection devices that infer as-yet unconfirmed defects. An “anomaly” deviates from what is standard, normal, or expected. The word “defect” is only used when the anomaly has been confirmed as an imperfection.
