ABSTRACT
Objective:
To analyze and compare the results and precision of three different methods to measure the surface dose of Intra-operative radiotherapy,and conclude some experience of clinical application in Intra- operative radiotherapy.Methods:
The study compared the results of measurement surface dose in phantom through three wayscylindrical ionization chamber with 3D water scanner,plane-parallel ionization chamber,and MOSFET detector.Results:
the measurement results of plane-parallel-chamber and MOSFET detector have a better consistency,and the maximum deviation is -1.13%.The method with cylindrical ionization chamber and 3D water scanner has larger deviation compare to the other two methods,the deviation range from-5.55%to 4.55%.Conclusion:
The methods of plane-parallel chamber and MOSFET detector to measure the surface dose of Intra-operative radiotherapy can obtain accurate results.
