    摘要: Embodiments of the claimed subject matter provide a radiation therapy system for the acquisition of volumetric imaging with advanced trajectories. Embodiments include a device for applying diagnostic and therapeutic radiation to a target volume disposed in a patient subject, wherein volumetric imaging is acquired with advanced trajectories without displacing the patient subject. In one embodiment, a radiation therapy device is provided comprising: a gantry with a radiation source and a plurality of independent robotic arms mounted to the gantry, wherein an X-ray source is attached to an end of one robotic arm; and an imager attached to an end of another second robotic arm.

    摘要: A filter changing assembly that can be used in, for example, a radiology system includes shape filters that can used to shape a radiation beam and that can be moved back-and-forth, for example. The filter changing assembly also includes beam hardening filters that can be used to change the energy spectrum of the radiation beam, and that also can be moved back-and-forth, for example. The filter changing assembly includes a control system that can be used to select at least one of the filters and automatically move the selected filter from one position to another position.
