EmpowerRT’s software technology, PLUNC, was developed at University of North Carolina as a temporary solution more than 20 years ago. For years, PLUNC enabled implementation of state- of -the-art radiation treatment clinically years ahead of centers relying on commercial software. During this time, PLUNC was provided for free to hundreds of cancer centers in many countries, especially developing countries.

As commercial systems have become better able to meet clinical needs, PLUNC was retired from service in 2016. The success of PLUNC inspired Dr. Chang to give a second life to the technology developed at UNC through EmpowerRT. Clinics across the globe that are reliant on older technology can implement EmpowerRT to provide personalized cancer care, using a clinically proven, affordable, and sustainable solution.
