| Research Abstract |
The purpose of this study was to develop the novel brachytherapy technique for various tumors that had never been treated including highly malignant schirrhous stomach carcinoma. First, novel applicator was designed so that the applicator can be swelled with great flexibility along the stomach wall. The dose measurement with this applicator was performed using film or BangGel. We found that film measurement was not suitable due to the response heterogeneity in the film. On the other hand, 3D gel dosimetry was found to be suitable owing to high spatial resolution and the dose around the stomach was rapidly fallen off. Further simulation study to examine the appropriate source position or radionuclide is required for appropriate treatment.
