An apparatus for patient position or motion monitoring includes: an energy source configured to emit energy from a first location to a second location, or vice versa, wherein the second location that is moveable relative to the first location in response to a movement by a patient; and a processing unit coupled to receive an input that is based on the emitted energy, and to determine a characteristic associated with the patient based on the input.

Systems and methods for detecting and/or measuring motion and position associated with a patient

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.

Systems, devices, and methods for imaging-based calibration of radiation treatment couch position compensations.

Imaging based calibration systems, devices, and methods

A radiation therapy system includes an X-ray imaging system that is configured with a combined and simplified filter and collimator positioning mechanism. In addition, an X-ray imager of the RT system is only positioned at a few discrete locations within a plane that is a fixed distance from the imaging X-ray source when generating X-ray images. As a result, for each of these discrete imaging positions, the simplified filter and collimator positioning mechanism positions a specific collimator-filter combination in a specific location between the X-ray source and the imager.

Systems, devices, and methods are presented for automatic tuning, calibration, and verification of radiation therapy systems comprising control elements configured to control parameters of the radiation therapy systems based on images obtained using electronic portal imaging devices (EPIDs) included in the radiation therapy system.

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.

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.

Patient supports for medical treatments

In an x-ray imaging method, the acquisition of a signal image is split off into acquisition of two or more subimages or frames. The first subimage may be acquired with an exposure of a low dose followed by a readout cycle. The dose of the exposure for acquiring the first subimage can be chosen such that it is below the default dose for a particular anatomy. The first subimage may be used to calculate or estimate the parameters of exposure for acquiring a second or subsequent images subimage. The estimation may be such that the total dose received by the imager, in acquiring the first and second subimages, achieves an expected target value to provide an image of good quality. The first and second subimages can be combined to form the final image. A detector array supporting automatic exposure control (AEC) includes AEC pixels providing AEC signals. The AEC pixels are independently or individually addressable and/or readable.

Automatic exposure control for x-ray imaging

A patient supporting device includes: a base configured to translate in a room; a first member having a first end and a second end, wherein the first end of the first member is rotatably coupled to the base so that the first member is rotatable relative to the base about a first vertical axis; a second member having a first end and a second end, wherein the first end of the second member is rotatably coupled to the second end of the first member so that the second member is rotatable relative to the first member about a second vertical axis; and a platform for supporting a patient, wherein the platform is rotatably coupled to the second end of the second member so that the platform is rotatable relative to the second member about a third vertical axis.
