COMPUTED-TOMOGRAPHY .1. INTRODUCTION AND INDUSTRIAL APPLICATIONS

X-ray computed tomography (CT) provides quantitative, readily interpre table data and enables the inspection of structures that are not amena ble to any other nondestructive evaluation technique. As a result, CT has become well established as an inspection, evaluation, and analysis tool in industry. Many of the applications have been in the aerospace industry, where the high cost and performance requirements of compone nts justifies the cost of CT inspection, but use in other industries i s growing as equipment becomes increasingly available.
