1. An integrated computed tomography (CT) treatment couch system, comprising:
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 including a support structure and a CT gantry,
the CT scanner device being configured to rotate around a beam isocenter of the medical accelerator based on the rotatable floor component,
the treatment couchtop being configured to move horizontally and independently of the pedestal component, to move a subject past the CT gantry and towards the beam isocenter,
the pedestal component and the base platform are not below the beam isocenter when the treatment couchtop is moved horizontally for the subject to arrive at the beam isocenter, and
the CT scanner device being configured to move horizontally and independently of the pedestal component, from one end of the pedestal component to an opposite end of the pedestal component and past the pedestal component,
the CT gantry having a bore, and being oriented such that the bore is in line with the treatment couchtop,
the CT gantry being configured to generate on-line CT scans to guide radiotherapy provided by the medical accelerator, and
the support structure being:
mounted to the base platform or to the pedestal component, in which axial, helical, and/or volumetric CT scans of a patient on the treatment couchtop are obtained via translational motion of the treatment couchtop along an axis passing through the bore of the CT gantry, or
configured to traverse a guided pathway coupled to, or incorporated on, the base platform, in which volumetric CT scans are obtained via:
translational motion of the treatment couchtop along the axis without translational motion of the CT gantry along the axis,
translational motion of the CT gantry via the guided pathway along the axis without translational motion of the treatment couchtop along the axis, or
combined translational motion of the treatment couchtop along the axis and the CT gantry via the guided pathway along the axis.
