Abstract: A couch top extension includes a first section and a second section extending from the first section. The first section has a varying shape profile and the second section has a substantially uniform shape profile. A couch top extension includes an extension board comprising one or more identifiers capable of providing a detectable signal indicative of an identification of the extension board.

Abstract: A patient supporting device includes: a base; a positioner; a platform having a first end and a second end; and a controller; wherein the positioner is operable by the controller to place the platform at one of a first plurality of possible positions or at one of a second plurality of possible positions, wherein in any of the first plurality of possible positions, the second end of the platform is closer to one of a left side and a right side of a treatment machine; wherein in any of the second plurality of possible positions, the second end of the platform is closer to another one of the left side and the right side; and wherein a size of a first spatial region defined by the first plurality of possible positions is different from a size of a second spatial region defined by the second plurality of possible positions.

Abstract: A computer-implemented method for a radiation therapy system includes: acquiring a first X-ray image of a region while the region is in a first location, the gantry is in a first imaging position, and a center axis of an imaging beam passes through an isocenter of the radiation therapy system along a first imaging path; acquiring a second X-ray image of the region while the region of patient anatomy is in the first location, the gantry is in a second imaging position, and the center axis of the imaging beam passes through the isocenter along a second imaging path, wherein an angle between the first imaging path and the second imaging path is a non-orthogonal angle; and based on the first X-ray image, the second X-ray image, and a three-dimensional treatment planning image of the region, determining an offset between a planning location for the region and the first location.
