Imaging during radiotherapy |
摘要 |
We provide a radiotherapy apparatus including a source of therapeutic radiation, a source of imaging radiation having an energy level less than that of the therapeutic radiation, a detector for radiation lying within the field of both the therapeutic radiation and the imaging radiation and able to image both, a first imaging circuit supplied with the output of the detector, a second imaging circuit also supplied with the output of the detector, a first pulse trigger circuit adapted to trigger the source of therapeutic radiation to produce a pulse of therapeutic radiation and to trigger the first imaging circuit to capture an output of the detector; and a second pulse trigger circuit adapted to trigger the source of imaging radiation to produce a pulse of imaging radiation and to trigger the second imaging circuit to capture an output of the detector. |

1. Radiotherapy apparatus comprising;
a source of therapeutic radiation, a source of imaging radiation having an energy level less than that of the therapeutic radiation, a detector for radiation, lying within the field of both the therapeutic radiation and the imaging radiation and able to image both, a first imaging circuit supplied with the output of the detector, a second imaging circuit also supplied with the output of the detector, a first pulse trigger circuit, adapted to trigger the source of therapeutic radiation to produce a pulse of therapeutic radiation, and to trigger the first imaging circuit to capture an output of the detector; and a second pulse trigger circuit, adapted to trigger the source of imaging radiation to produce a pulse of imaging radiation, and to trigger the second imaging circuit to capture an output of the detector. |
