Re: New method for detection CUI : On Michael Twomery's article it is mentioned that originally it appeared in the Dec 1996 issue of the Inspectioneering Journal. It is possible that today other methods are available or undergoing investigations. In our ASNT '97 Fall conference report we reviewed the use of Ultrasonic Guided Waves for CUI .
: I anticipate that the new book  of an NTIAC's work will be a comprehensive state-of-the-art report on CUI. : We will update this information also at our Publication department.

One aspect of the real time radiography described by Twomery is that the imaged area is small (about one inch in diameter). This leads to a large POD for large CUI defect and a low POD for pitting. Also the scan pattern will affect POD. A choice for delagging or real time X-ray would require some knowledge on POD. Has someone made a study of this?
