| Research Abstract |
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.
Results : For the phantom with bone 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.
This study was published in Radiology Research and Practice.
