An imaging facility having an X-ray source, an X-ray detector, and a rotation facility operable to rotate the X-ray source and the X-ray detector around a center of rotation. The imaging facility also has a first translation facility operable to move the X-ray source in a direction that has a component that is tangential to a circle of rotation around the center of rotation.

Imaging facility and radiation therapy device

A system for motion control of a cone-beam tomography recording device includes a drive system configured to position a paired radiation source and radiation detector relative to an object. The system further includes a controller configured to: initiate a trigger plan operable as a function of a constant frequency control signal, activate the paired radiation source and radiation detector in accordance with the trigger plan, drive, in response to the trigger plan, the first drive system to a steady operating state derived as a function of the constant frequency, capture a plurality of broadcast radiation signals representative of a plurality of two dimensional images of the object such that the two dimensional images are defined equidistant positions defined by the trigger plan and as a function of the constant frequency signal, and generate a three dimensional representation of the object based on the plurality of two dimensional images.

System and method for recording cone-beam tomograms in radiation therapy

A radiotherapy device having a gantry rotatably mounted to the radiotherapy device with a bearing and a counterweight attached to the gantry. The counterweight has a spatial position relative to the gantry. The spatial position of the counterweight is movable. The device is configured to generate a compensating torque on the bearing, the compensating torque based on a movement of the spatial position of the counterweight, to balance the gantry.
