Ion beam therapy system and its couch positioning method |
摘要 |
A therapy system using an ion beam, which can shorten the time required for positioning a couch (patient). The therapy system using the ion beam comprises a rotating gantry provided with an ion beam delivery unit including an X-ray tube. An X-ray detecting device having a plurality of X-ray detectors can be moved in the direction of a rotation axis of the rotating gantry. A couch on which a patient is lying is moved until a tumor substantially reaches an extension of an ion beam path in the irradiating unit. The X-ray tube is positioned on the ion beam path and the X-ray detecting device is positioned on the extension of the ion beam path. With rotation of the rotating gantry, both the X-ray tube emitting an X-ray and the X-ray detecting device revolve around the patient. The X-ray is emitted to the patient and detected by the X-ray detectors after penetrating the patient. Tomographic information of the patient is formed based on signals outputted from the X-ray detectors. Information for positioning the couch is generated by using the tomographic information.
