May Technical Meeting – Metrology in CT Imaging

May 19, 2020 @ 6:30 PM - 9:00 PM EDT

Hello all,

I hope everyone is staying healthy and safe! I would like to extend an invitation to our first WEBEX meeting hosted by the Rockford Stateline ASNT Section. It will be a joint meeting with Rockford Stateline, Chicago and Houston ASNT Sections. This meeting is free of charge and attendees can earn points for recertification.

To be eligible for recertification points, you will need to participate for the entire portion of the technical meeting. In order to earn credit, we ask for a specific item:

When you log into the WebEx meeting, identify yourself using your first and last name, as recorded with ASNT and a dash and a three letter abbreviation for your section.

Examples: Joel Mohnacky – RFD
James Kretzler – PIT

From this, a meeting report with your name and email will be generated. Contact your chair and request validation for your points. Your chair will email you with a confirmation of attendance and you can print that email as objective evidence for your files for recertification.

This meeting presenter will be: Dana Begun, Ph.D from Waygate Technologies.


Metrology in CT Imaging


The advancement of 3D printing and additive technologies has led to growing demand for new measurement strategies. In order to meet the new challenges in the manufacturing industry, industrial CT has become a critical tool for inspections requiring metrological rigor.

Here we will explore the basics of metrology by CT and a discussion of the major factors that influence the metrological performance. Furthermore, we will discuss the challenges that arise when using a CT system for Geometric Dimensioning & Tolerance (GD&T) projects and present the technical solutions that are necessary to make CT measurements accurate and precise.

Brief Bio on the Speaker:

Dana Begun is an applications engineer at Waygate Technologies specializing in CT and X-ray imaging. She holds a dual Ph.D. from the University of Michigan in Biomedical Engineering and Anthropology. Following a post-doctoral fellowship at the Mayo Clinic, she joined the Waygate applications team in 2018. She has 13 years of experience with radiographic technology. In addition to her role at Waygate, she is a member of ASNT and ASTM. Dana has also recently taken on the role of instructor for the 40-hour CT course through the Baker Hughes Inspection Academy.

Please plan to join us for this unique presentation and meeting format.
