A surgical positioning system includes a flexible air-impermeable shell filled with beads that is wrapped against the patient and subjected to a vacuum to hold the patient in place. An air-impermeable top wall can be joined with an air-impermeable bottom wall to define a plurality of chambers. Each of the chambers can include a peripheral edge that extends around the periphery of the respective chamber. The plurality of chambers can include a first shoulder chamber, a second shoulder chamber, and a main chamber.

A surgical boot system and sleeve accessory for hip distraction. The surgical boot system includes an L-shaped rigid shell having a proximal portion and a distal portion. A soft liner is attached to the rigid shell and extends along at least one of the proximal portion and the distal portion. The surgical boot system also includes at least one strap assembly (which can be a plurality of strap assemblies) extending around the rigid shell. A load transmission hoop is connected to and extends around the distal portion of the rigid shell and an attachment point is connected to the load transmission hoop. The rigid shell is pivotable about the attachment point. Specifically, the attachment point is configured to interface with a hip distractor apparatus in a way that allows for multiple degrees of freedom.

A method of preparing a patient positioning system for reuse includes obtaining a used inflatable device, the used inflatable device comprising at least one connection mechanism for coupling to a high-friction pad. The method also includes performing a replacement of an original high-friction pad that was used with the used inflatable device.

A radiation therapy system may be provided. The system may include a therapeutic apparatus. The therapeutic apparatus may include a radiation source for directing therapeutic radiation to at least one portion of a region of interest (ROI) of a subject, and an immobilizing device for immobilizing the subject. The system may obtain characteristics information of the subject. The system may preheat the immobilizing device according to a predictive model that processes the characteristics information of the subject. The system may send a control signal to the therapeutic apparatus for applying the therapeutic radiation to the at least one portion of the ROI immobilized by the preheated immobilizing device when the immobilizing device is preheated to a certain temperature.
