In an embodiment, a system comprises a first display in communication with a server, the first display configured to display a first graphical user interface; a second display in communication with the server, the second display configured to display a second graphical user interface, wherein the server is configured to: present the first graphical user interface for displaying on the first display, wherein the first graphical user interface contains one or more pages corresponding to one or more stages of a radiotherapy treatment, wherein the server transitions from a first page of the one or more pages representing a first stage to a second page of the one or more pages representing a second stage responsive to an indication that at least a predetermined portion of tasks associated with the first stage has been satisfied.

A radioactive ray radiation system includes a beam radiation apparatus, a treatment planning module, a control module, a preparation room and a radiation room. First and second stereoscopic vision apparatuses are respectively arranged in the preparation room and the radiation room. Simulated positioning is performed on a radiated subject in the preparation room according to the location of a radiated part determined in a treatment plan, and a first image of the radiated part collected by the first stereoscopic vision apparatus is compared with the treatment plan to determine a simulated positioning pose. Radiation positioning is performed on the radiated subject in the radiation room according to the determined simulated positioning pose, and a second image of the radiated part collected by the second stereoscopic vision apparatus is compared with the treatment plan to control the beam radiation apparatus to start performing radiation therapy on the radiated subject.

A method of operating imaging and tracking. The method includes determining, for each angle of a plurality of angles from which tracking images can be generated by an imaging device, a value of a tracking quality metric for tracking a target based on an analysis of a projection generated at that angle. The method also includes selecting, by a processing device, a subset of the plurality of angles that have a tracking quality metric value that satisfies a tracking quality metric criterion, one or more angles of the subset to be used to generate a tracking image of the target during a treatment stage, wherein the subset comprises at least a first angle and a second angle that is at least separated by a minimum threshold from the first angle.

A computer-implemented tumor position determining model is trained, based on a plurality of sets of image data, to determine a subsequent position of a tumor in a subject based on a subsequent 2D or 3D representation of a surface of the subject, an initial image of the tumor in the subject and an initial 2D or 3D representation of a surface of the subject. Each set of image data comprises an initial training image of a tumor in a subject, an initial training 2D or 3D representation of a surface of the subject, a subsequent training image of the tumor in the subject and a subsequent training 2D or 3D representation of a surface of the subject. The subsequent training image and the subsequent training 2D or 3D representation are taken at a subsequent point in time than the initial training image and the initial training 2D or 3D representation and the plurality of sets of image data are from a plurality of different subjects.

A radiation treatment session is initiated to deliver a therapeutic radiation beam from a therapeutic radiation source to a target. One or more X-ray radiation sources are caused to deliver an imaging radiation beam from the one or more X-ray radiation sources through the target to one or more X-ray detectors to acquire imaging data associated with the target during therapeutic radiation beam delivery. One or more volumetric images are constructed using the acquired imaging data.
