Advanced CT (CT Level II) (40 Hours)

This course is for the advanced CT system user who already has a strong understanding of digital X-ray principals and is ready to take their CT scanning to the next level. The DR and CT (Level I) class is strongly recommended as a preparation for this course.

Attendees will learn advanced CT acquisition and reconstruction techniques for use in nearly all industries. Topics include: Advanced technique development, fixturing for successful scans, understanding scan speed, sensitivity and resolution and the trade-offs associated with each, product evaluation requirements and RQI’s, managing data set size, optimizing scan geometry, understanding factors relating to measurements and dimensional accuracy, advanced techniques for quality reconstructions, and much more.

This course includes recommended curriculum for CT Level II personnel training as recommended in ASTN SNT-TC-1A.


This class is worth 40 Contract Hours that can be applied to various industry certification and continuing education requirements, including ASNT, SNT-TC-1A, NAS-410 and MAI/FWG-IDR.
