摘要： A linear accelerator target apparatus includes a target material to produce radiation upon being struck by electrons accelerated by a linear accelerator and a target holder assembly to which the target material is attached. The target holder assembly includes a cooling channel disposed around a perimeter of the target material. The target holder assembly is configured to be detachably coupled to a housing of the linear accelerator. The target apparatus further includes a protective window coupled to the target holder assembly over the target material.

摘要： Electromagnetic waves for an accelerating structure of the radiation delivery system are generated by a microwave source. The electromagnetic waves generated by the microwave source are adjusted by an energy adjuster to an imaging energy level. A kilovolt (kV) imaging beam is generated by the accelerating structure based on the imaging energy level. The electromagnetic waves generated by the magnetic source are adjusted by the energy adjuster to a treatment energy level. A megavolt (MV) treatment beam is generated by the accelerating structure based on the treatment energy level.

摘要： A radiation delivery system that includes a gantry to extend along one or more axes. The gantry is to provide a continuous rotation. The radiation delivery system includes a linear accelerator (LINAC) coupled to the gantry. The LINAC is to generate a treatment beam. The radiation delivery system includes a rotary joint coupled to the gantry. The rotary joint provides a physical connection from the LINAC to an external system that is positioned off the gantry. The physical connection is to transport at least one of a cooling liquid or air.
