Abstract：Objective To study the method and feasibility of the computer judgment and analysis method for the image of CT quality
control phantom performance test, and compare it with the conventional method. Methods Scanning CT performance phantom,
the spatial resolution, low contrast resolution, noise, CT value and uniformity were measured by computer automatic analysis and
conventional detection method. Results The results showed that the performance index of CT was judged based on computer
software and conventional testing method. The results were consistent between software measurement and traditional measurement,
and the method of CT intelligent quality control based on computer software was feasible. Conclusion Through the intelligent
measurement of CT image performance index, it can evaluate the performance of CT equipment more objectively and accurately,
reduce manual error, and improves the efficiency of CT quality control greatly.
