In radiation therapy strategies, the treatment planning system (TPS) is dispensable for simulate the absorbed dose distribution in patients is indispensable. The dose distribution is calculated using the beam model created from the beam profile that is unique to each Linac, but the model greatly differs depending on detector used for profile measurements. Particularly in intensity-modulated radiation therapy (IMRT) and stereotactic radiotherapy (SRT) that use many small irradiation fields, the difference in beam model has large influence on the dose calculation results, and it is necessary to select an appropriate detector to evaluate dose distribution accurately.
