A system for determining a position or an orientation of a probe across a drape may include a fiducial assembly that may be coupled to the probe though a drape. The fiducial assembly may include a base, a coupling attached to the base which may be configured to couple the fiducial assembly to the probe across the drape, and one or more fiducials attached to the base. Coupling the fiducials to the probe across the drape can allow sterile fiducials to be coupled to a non-sterile probe to determine the position and orientation of the probe based on images from the of the fiducials on a sterile side of the drape. In some embodiments, the fiducial is aligned with respect to an elongate axis of the probe with a predetermined offset and orientation with respect to the elongate axis of the probe.

Fiducial systems for probe tracking and identification

Disclosed are radiation treatment systems with enhanced control architectures that enable more complex treatment plans to be implemented, and radiation treatment systems with enhanced resistance to the effect of neutrons. An exemplary control architectures comprises: a digital packet network; a supervisor electrically coupled to the digital packet network and having a treatment plan; and a plurality of nodes, each node coupled to digital packet network and controlling one or more treatment-related components of the radiation treatment system; and wherein the supervisor periodically communicates control orders to the nodes over the digital packet network.

Radiation treatment systems

A radiation device directs a beam of radiation onto a target. The beam can be adjusted using, for example, a control for setting beam shape and a control for setting beam intensity. The target is supported on a surface that can be adjusted using, for example, a control for setting surface position and a control for setting a speed for moving the surface. Controls are selected to adjust the beam and the surface cooperatively in order to compensate for movement of the target.
