Abstract:: Abstract: A MATLAB-based dosimetric data processing and analysis toolkit using radiochromic film (RCF) is designed and developed to meet the needs of using RCF for quick quality assurance and off-line deep analysis. The toolkit is composed of a graphical user’s interface program and a modular function set. The graphical user’s interface program is implemented on a pipeline workflow for data input and processing and the calculation of key dosimetric indexes such as field size, full width at half maximum, maximum dose depth. The function set of function module can be called independently, and intermediate variables are accessible. Moreover, the function set of function module which has high versatility for data processing and analysis can be further developed. The designed toolkit is believed to provide strong technical support for using RCF to perform the dosimetric quality assurance of radiotherapy, thereby improving the efficiency of quality assurance and increasing resource efficiency.
