| Research Abstract |
In the clinical evaluation of lung cancer for radiotherapy, fiber-optic bronchoscopy is a crucial tool in the diagnosis of the tumor region before the treatment and in the evaluation of dose responses on tumor and normal tissues after the treatment. The conventional display for planning dose distribution is multi-planner reconstruction system, so it is so complex to correlate the dose distribution with the bronchoscopic image. To estimate effects of irradiation on lung tumor around bronchi, we have developed the unique visualizing system of planning dose distribution on virtual bronchoscopic images.
Clinical evaluation by this system was performed clinical cases of lung cancer treated with carbon-ion radiotherapy. The validity of the planned dose distribution has been checked from tissue responses such as tumor disappearance and bronchial obstruction after irradiation.
