中心分割法の臨床的応用

In 1979, we published an article about an alternate irradiation system in the Japanese Journal of Radiological Technology. This system was very useful for wide local radiation. In the present study, we examined the usefulness of this system in T-shape fields for patients bearing esophageal cancer, lung cancer, etc; in a 90° angle, two-portal teratment for a patient with maxillary cancer, and in a tangencial treatment for a patient bearing a rib metastatic tumor. The system was very useful, and side effects were minimal.
