摘要： An integrated computed tomography (CT) treatment couch system may include a base platform configured to couple to a rotatable floor component associated with a medical accelerator, a pedestal component mounted to the base platform, a treatment couchtop disposed on the pedestal component, and a CT scanner device. The CT scanner device may include a support structure and a CT gantry. The support structure may be mounted to the base platform or to the pedestal component. The CT gantry may have a bore and may be oriented such that the bore is in line with the treatment couchtop. The CT gantry may be configured to generate on-line helical CT scans to guide radiotherapy provided by the medical accelerator.

摘要： An x-ray irradiation system includes a first x-ray tube constructed and arranged to be able to irradiate an object with at least a portion of a first x-ray beam emitted from the first x-ray tube, and a second x-ray tube constructed and arranged to be able to irradiate the object with at least a portion of a second x-ray beam emitted from said second x-ray tube simultaneously with said first x-ray beam. The first and second x-ray tubes are arranged such that the first and second x-ray beams are incident on, and intersect within, the object at respective first and second oblique angles to define a target volume such that a dose rate is substantially uniform as prescribed within said target volume.
