Method and apparatus for diagnostic imaging in radiation therapy
An imaging apparatus is described in combination with conventional radiation therapy equipment consisting of a gantry having a high-energy radiation source capable of emitting a high-energy radiation beam and having shielding blocks, the gantry being disposed for irradiation of a stationary patient positioned on a gurney at a fixed distance from the high-energy radiation source, the apparatus comprising the following components: a low-energy radiation source capable of emitting a low energy radiation beam and mounted on a side of the gantry opposite to the high-energy radiation source, such that the beam from the low-energy radiation source is coaxial with the beam from the high-energy radiation source; and a radiation detector mounted between the high-energy radiation source and the low-energy radiation source so as to be between the high-energy radiation source and the patient's gurney, the detector being positioned so that it can be exposed to both the high-energy beam and the low-energy beam; wherein the low-energy radiation source and the detector are used to irradiate the patient and obtain diagnostic images of the patient before treatment with the high-energy beam and to obtain verification images of the patient's position for proper therapeutic irradiation during treatment.
