A method includes receiving during a first time interval associated with a path of motion of a dynamic body, image data associated with a plurality of images of the dynamic body. The plurality of images include an indication of a position of a first marker coupled to a garment at a first location, and a position of a second marker coupled to the garment at a second location. The garment is coupled to the dynamic body. During a second time interval, an image from the plurality of images is automatically identified that includes a position of the first marker that is substantially the same as a position of a first localization element relative to the dynamic body and a position of the second marker that is substantially the same as a position of the second localization element relative to the dynamic body.

Systems for immobilizing a patient are disclosed. The system includes at least one preform formed from a low melting temperature thermoplastic, the preform being configured to be formed to the anatomy of the patient, at least one frame coupled to the at least one preform, and at least one support configured to support the anatomy of the patient. The system also includes at least one lock mechanism coupled to at least one of the frame and the support and configured to couple the at least one frame to the at least one support, and at least one adjuster mechanism coupled to at least one of the at least one frame and the at least one support and configured to selectively adjust a distance between the at least one frame and the at least one support while the at least one frame is coupled to the at least one support.

A method for forming a preform for a thermoplastic retention device is provided. The method includes providing a thermoplastic base material and blending the base material with one or more chemical agents to form a polymer blend. The chemical agents are configured to modify a polymer chain of the base material when the polymer blend is exposed to radiation. The method further includes forming the polymer blend into a filament sized for a three-dimensional printing platform and printing a preform shape from the filament using the three-dimensional printing platform. After the printed preform is hardened, the method includes exposing the printed preform shape to radiation sufficient to cause a reaction between the one or more chemical agents and the base material.

A mask positioning assembly is provided. The mask positioning assembly includes a cradle frame, an adapter frame, and a positioning mask. The cradle frame is connected to both the adapter frame and the positioning mask. The adapter frame can be configured to be connected to any of positioning assembly support frames in different types of positioning systems. A positioning system is also provided.

Systems for immobilizing a patient are disclosed. The system includes at least one preform formed from a low melting temperature thermoplastic, so that the preform may be formed to the anatomy of the patient, at least one frame coupled to the at least one preform, and at least one support to support the anatomy of the patient. The system also includes at least one lock mechanism coupled to at least one of the frame and the support in order to couple the at least one frame to the at least one support, and at least one adjuster mechanism coupled to at least one of the at least one frame and the at least one support in order to selectively adjust a distance between the at least one frame and the at least one support while the at least one frame is coupled to the at least one support.
