Objective:To design an intelligent measurement program of detection parameters of quality control of imaging system of multi-slice spiral computed tomography(MSCT)based on MATLAB software platform,so as to achieve intelligent detection for quality control of MSCT imaging system.Methods:We designed an intelligent measurement program for the detection parameters of quality control of MSCT imaging system(referred to as the intelligent measurement program)bases on the function of graphical user interfaces(GUI)of MATLAB software.A series of algorithms such as image reading,binarization,and circular detection based on the Hough transform were employed to conduct automatic measurement and calculation for CT values(water),noise and uniformity of the parameters of MSCT quality control.The Intraclass Correlation Coefficient(ICC)was adopted to analyze the consistency of the detection results between the manual measurement method and the designed intelligent detection program.Results:The designed intelligent measurement program in this study can automatically assess the detection parameters of quality control of the MSCT imaging system,which included CT values(water),noise and uniformity.There was favorable consistency in the detection results between the manual measurement method and the intelligent measurement program(range of ICC values was from 0.881 to 0.985).Conclusion:The intelligent measurement program of detection parameters of quality control of MSCT imaging system can simplify the process of calculating detection parameters of quality control of MSCT imaging system,and provide a reliable detection tool for quality control of MSCT imaging equipment,which can effectively improve the detection efficiency of quality control.
