When TG-142 was released, the intention was to give physicists
guidance on quality assurance for technologies that, at the time, were
new. These guidelines were meant to be flexible enough for physicists to
effectively implement the proper testing in their clinics.
Soon after, we began working on TG-198, a guide to how to deploy
TG-142. This TG dives into more specifics, including some recommended
instruments to use in imaging and treatment machine QA, and an estimate
of the amount of time, personnel, and qualifications it takes to do the
Whereas TG-142 is primarily performance-based QA, comparing test
results with historical results, TG-198 is more prescriptive. The goal
is to increase the quality of the QA process itself, taking into account
the evolution of technology.
My QADS presentation will introduce some of the concepts from TG-198,
which is a work in progress. I will also touch on some of the new
technologies that come into play when we think about imaging and machine
I hope attendees will walk away with some actionable information they
can use to plan, and make a strong case for the resources needed for
treatment machine and imaging QA.
