Stereotactic radiosurgery method and apparatus |
摘要 |
Radiation is generated toward a patient. A radiographic region of the radiation covers a predetermined field-of-view. Both of a stereotactic radiation producing filter and a radiographic radiation producing filter are transported in such a way that the stereotactic radiation producing filter and the radiographic radiation producing filter sequentially intercept the beam axis between the patient and a generation position for the radiation. When the stereotactic radiation producing filter is located on the beam axis, it forms the radiation into radiation required for stereotactic radiosurgery. When the radiographic radiation producing filter is located on the beam axis, it forms the radiation into radiation required for radioscopy. Radiation present within the radiographic region is detected with employment of a radiation detecting unit positioned opposite to the generation position of the radiation with respect to the patient. The radiation is generated when the stereotactic radiation producing filter is located on the beam axis and the radiographic radiation producing filter is located on the beam axis.
