Abstract: A method of robotic patient positioning for radiation treatment using a radiation source with an arm assembly rotatably connected to a support device is described. The method includes moving the support device with respect to the radiation source in at least five degrees of freedom to align a treatment target with respect to the radiation source. Moving the support device includes rotating the support device about first, second and third rotational axes and rotating the arm assembly about fourth and fifth rotational axes. Rotations about the fourth and fifth rotational axes translate the support device for fourth and fifth degrees of freedom of the at least five degrees of freedom.

Abstract: An interface is provided to a user to perform a plurality of treatment planning operations associated with the treatment plan before the treatment plan is optimized. The treatment planning operations include at least one of selecting a treatment planning parameter or inputting data corresponding to the treatment planning parameter. One or more templates containing one or more pre-defined treatment planning parameters are provided to the user to enable the user to skip performing one or more of the plurality of operations.

Abstract: An apparatus and method for optimizing a workspace of a radiation treatment delivery system. An optimized treatment plan is generated for delivering a dose of radiation to a volume of interest (“VOI”) in a patient using fewer changes to a treatment plan parameter during delivery of the dose of radiation then available to a radiation treatment delivery system. The optimized treatment plan limits a number of adjustments to the treatment plan parameter during delivery of the dose of radiation. Prior to delivery, the optimized treatment plan is analyzed to determine whether a quality of the optimized treatment plan is acceptable.

Abstract: A respiration phantom that may be used to perform quality assurance on a radiation delivery system. The respiration phantom includes a human-like skeletal structure, at least one deformable component, and a respiration actuator. The deformable component is positionable at least partially internal to the human-like skeletal structure, has a shape resembling an organ of a human anatomy, and attenuates radiation substantially similarly to the organ of the human anatomy. The respiration actuator is positioned to deform the deformable component with a respiration-like motion.

Abstract: A wireless treatment target positioning system for therapeutic radiation treatment includes a patient positioning system and a treatment target locating system. The treatment target locating system includes a room beam coordinate system and a localizing system. The room beam coordinate system includes devices for generating laser beams intersecting at a single point that is spatially coincident with an iso-center of the treatment system.
