Abstract EN
Purpose.
To assess differences in dose distribution of a vertebral body injected with bone cement as calculated by radiation treatment planning system (RTPS) and actual dose distribution.
Methods.
We prepared two water-equivalent phantoms with cement, and the other two phantoms without cement.
The bulk density of the bone cement was imported into RTPS to reduce error from high CT values.
A dose distribution map for the phantoms with and without cement was calculated using RTPS with clinical setting and with the bulk density importing.
Actual dose distribution was measured by the film density.
Dose distribution as calculated by RTPS was compared to the dose distribution measured by the film dosimetry.
Results.
For the phantom with cement, dose distribution was distorted for the areas corresponding to inside the cement and on the ventral side of the cement.
However, dose distribution based on film dosimetry was undistorted behind the cement and dose increases were seen inside cement and around the cement.
With the equivalent phantom with bone cement, differences were seen between dose distribution calculated by RTPS and that measured by the film dosimetry.
Conclusion.
The dose distribution of an area containing bone cement calculated using RTPS differs from actual dose distribution.
