内容記述 | [Objective] In the treatment planning, it is very difficult to comprehend the dose distribution on the endobronchial tumor or epithelium. So we developed the software to superimpose the color map of planning dose distribution on virtual bronchoscopic images. [Materials and Methods] Respiratory gated CT images using multi-detector CT scanner (GEY MS Ltd.; Light Speed Ultar16, 0.5 seconds/rotation) is taken for the patient of lung cancer. Treatment planning is performed to a set of gated CT image using a HIPLAN which is treatment planning system for carbon-ion radiotherapy (ICRT) developed in our institute. Then the isocenter information file, dose distribution files at each filed and a set of CT volume file are inputted to application software of virtual bronchoscopy which were based on commercial software of virtual bronchoscopy (AZE Ltd. Virtual Place Advance Plus. Ver.2). Following the geometrical adjustment and interpolation with CT images and dose distribution, the 3-dimensional voxel data set is reconstructed. [Results] Planning dose distribution at each filed or total filed was visualized on the endobronchial surface of virtual bronchoscopy, and was simultaneously displayed on axial, sagittal and coronal multiplanar reconstruction CT images, too. When the observing point on virtual bronchoscopy is moved on the 3-dimensional bronchoscopic image by interactive exploration, the bronchoscopic image with dose map was obtained in real-time. [Conclusions] We developed the unique dose distribution display system on virtual bronchoscopy. This system is emerging as a useful approach for evaluation of bronchial dose response in comparison of actual bronchoscopic images. |
