Abstract

In order to compare and evaluate the parameters of the modules for Computed Tomography (CT) number, and check the performance of high contrast resolution, low contrast resolution, image uniformity of CT performance phantoms, approximately one hundred CT performance phantoms were tested under the same clinical conditions. The experimental results indicate that there are variations testing results to the different CT performance phantoms in despite of using the same CT scanner. The results showed that in order to meet the requirements of CT performance test, CT performance phantom standard should be established and traceability.
