| Outline of Final Research Achievements |
In order to construct a system to improve the accuracy of radiotherapy for lung malignant tumors, we conducted a study to predict lung motion by measuring electrical signals of respiratory muscles on chest surface. The movement of lung was measured with a fluoroscopic image and the signal of respiratory muscles was measured by placing the electrode of the electromyogrammeter on chest surface, and the relationship between the two was analyzed. The results showed that the electric signals of respiratory muscles contain noise, and we could not construct a system that detects the electrical signal of respiratory muscles prior to respiratory movement. It seems that the system construction required more data volume than that was considered necessary at the time of research planning.
