Abstract:
Objective: The reliability of multiple exposure technique in QA imaging was evaluated by combining IP plate of X-ray radiography and homemade QA verification plate. Methods: The QA verification films with different properties derived from placing the QA verification plate and the IP plate on corresponding location were compared with established traditional QA methods. Results: The data from verification films of light and radiation field overlapping derived from combining QA verification plate and IP plate were analyzed by eFilm software in 10cm×10cm radiation field. The results were similar with that of 3D water tank scanning, and were basically same with the analytical results collected from the PTW 2D-ARRAY729 matrix. Conclusion:Using described method in this paper, the result was accurate, the operation was easy, and the cost was low. This method was of good practicability.
