Principles Of CT Artifact Management

This module introduces the essential principles of CT artifact prevention and explains how beam hardening motion metal streaking and reconstruction limitations influence image quality. It describes how technologists identify artifact patterns evaluate their causes and apply corrective strategies. The content highlights the importance of understanding how slice thickness pitch detector configuration and reconstruction algorithms contribute to artifact formation. It also explains how patient communication immobilization and breath hold coaching reduce motion related issues. The module emphasizes the importance of recognizing artifacts that obscure anatomy or mimic pathology. By understanding how CT artifacts arise technologists can improve image quality reduce repeat exams and support accurate diagnosis.

Common CT Artifacts And Their Sources

This section explains the origins of beam hardening metal streaking partial volume and motion artifacts.

Techniques For Artifact Reduction

This section focuses on adjusting parameters including kVp mAs pitch and reconstruction kernels to minimize artifacts.
