System mocujący bolus wodny – zastosowanie w praktyce radioterapeutycznej


Author(s): Krzysztof Patyra, Maria Mazurkiewicz

Introduction: The aim of the work was the construction of a fixing system for the water bolus, the evaluation of its application in radiotherapeutical practice or the comparison of the distribution of the dose obtained in the volume of 95% PTV when using the presently applied rubber and gel boluses with the system of water bolus.

Material and method: The first phase of the research was a conceptual work over the creation of a system fixing the water bolus. The graphic project of such system was created, and then the prototype of the device was made that is the frame fixing the water bolus. The evaluation of the distribution of the dose in the PTV volume was carried out on a manikin. The trial localization was the area of the head and the neck. The manikin was situated in the frame fixing the water bolus. Next, the CAT scanning was made for the planning of the treatment for the hypothetical localization of the neoplasmic tumour. The CAT scanning for the same localization was made also with the application of gel and rubber bolus. The symbolic area of PTV was indicated on the obtained cross section, and then it was sent to the system of treatment planning. The evaluation of the distribution of the dose in the volume of PTV for each type of bolus was carried out on the base of histogram analysis.

Results: The use of the water bolus permitted to achieve around 98% of the planned dose in 95% of PTV.

Conclusions: The constructed system of fixing the water bolus allows for its very good stabilization and the reproducibility of the radiation conditions in the following days of irradiation treatment. The obtained distributions of irradiation dose in the volume of 95% PTV weigh in favour of the application of water bolus system.
