Tutorial: Fundamentals and Applications of Digital Image Processing for Radiography

Date: 21 Jul 2009 - 21 Jul 2009

Venue: SIMTech Training Rooms, Level 3

Introduction
The purpose of this tutorial session is to provide training in the use of image processing for radiography. Topics include the following:
·         Image viewing and basic functions such as contrast, brightness, gamma, correction and histogram correction 
·        Basic filters (high and low pass, median) 
·         Measurement of basic spatial resolution (based on CEN and ASTM standards) 
·         Measurement of signal noise and contrast noise ratio (based on CEN and ASTM standards) 
·    Long term stability for Computed Radiography by the standardised phantom 
·         Wall thickness measurement and corrosion depth measurement fortangential and double wall technique 
·         Comparison of digital radiographs

 

This is a theory cum demonstration tutorial in which participants will be provided with individual computers and software for hands-on practical interactive training during the session. Personal notebooks/laptops (Windows XP, CD/DVD-Drive) may also be used. 
Participation is limited to a maximum of 24 to allow for effective interaction with the presenter.

About the Speaker
Professor Dr Uwe Ewert obtained a diploma degree for physical and theoretical chemistry from the Humboldt University in Berlin in 1974. He received a PhD for a thesis on simulation of electron spin resonance (ESR) spectra in 1979. He managed the application laboratory for ESR-spectroscopy at the Centre for Scientific Instruments (CSI) of the academy of sciences in Berlin from 1980-1989. Dr Ewert was guest faculty at the Baker Laboratory of the Cornell University in USA from 1989-1990. He is affiliated with the federal institute for materials research and testing (BAM) since 1992 and was head of the laboratory “radiation methods” from 1992 – 2000. In 2000 he was appointed as director and professor of the division “Nondestructive testing; radiology” at BAM. He is elected chairman of the German radiology committee of the German society of NDT (DGZfP; since 1997), member of the advisory board of DGZfP (since 1999) and chairman of the subcommission VA (radiation methods for welding) of the International Institute of Welding (IIW; since 2000). He is delegate at several standard committees of ISO, CEN and ASTM.
