Managing a Successful Transition from Film to Digital Radiography: Part Two of Two

So often, the scheduling and time it takes to learn technique development and obtain operator certification is underestimated, but with good planning both can be managed efficiently. Many new users wait until they receive their X-ray machine to start the training process, take time to learn the techniques, and then start the customer approval process. This can take much longer than anticipated, so any opportunity to begin these processes early is a best practice approach. 

In the first part of this series, "Managing a Successful Transition from Film to Digital Radiography," we examined how a non-destructive test operation would begin to make the transition from film to digital X-ray system:

1. Understand & Define Requirements
2. Review Applicable Industry Standards
3. Prove & Demonstrate Capability
4. Recommend the Ideal Solution

In the second part of the series, we discuss the next steps involved in moving toward a standards-compliant digital radiography nondestructive test process. The following exerpt from Part Two looks at how to transition your Technique Development and Operator Certification programs.

Beginning technique development process early is one way new digital imaging operators have increased their success. They simply use the same application resources used to qualify the potential system. Several vendors offer to include this as part of their project. Make sure you inquire if this process is included in your purchase, and ask them to provide a first draft of a technique to submit to the end customer. This should help cut the time involved in the approval process.

The training needed is often put near the end of the project, but many times it is possible to get this step out of the way, even before the system is delivered to you. For example, operators in training could use digital images acquired on other systems at different plants (shared digitally) to start accumulating digital inspection hours required for operator certification. Investing in both theoretical training in a classroom and virtual “hands-on” training can give you a head start for your system approval.
