A method for collision detection of a radiotherapy equipment includes determining a collision-prone position of a target to be detected; and determining whether the target to be detected having a risk of collision with the radiotherapy equipment according to collision risk analysis data that is capable for reflecting a magnitude relationship between a first distance and a second distance. The first distance is a distance from the collision-prone position to a reference position of the radiotherapy equipment, and the second distance is a minimum distance between a target component of the radiotherapy equipment and the reference position. A distance between the reference position and the target component of the radiotherapy equipment is relatively constant when the target component of the radiotherapy equipment rotates around a rotation axis.

A radiation therapy apparatus that enhances the reliability and ease of use of a treatment is provided. A radiation therapy apparatus includes: a treatment bed moving a top plate with an object to be treated Pt placed on the top plate to a predetermined treatment location; an imaging apparatus moving to the predetermined treatment location from a direction different from the direction of movement of the top plate and picking up an image of the object to be treated; and an irradiation apparatus provided between the treatment bed and the imaging apparatus, extensible, and applying a radioactive ray to the object to be treated. When the CT apparatus moves to the treatment location, the irradiation apparatus moves to a predetermined waiting position P1. When applying a radioactive ray to an object to be treated, the irradiation apparatus moves to a predetermined irradiation position P3.

A method is described including online selecting of at least one of a plurality of optimal imaging times or a plurality of imaging angles and optimizing a parameter of an imaging system based on the online selecting.

Disclosed herein are radiotherapy systems and methods that can display a workflow-oriented graphical user interface(s). In an embodiment, a system comprises a radiotherapy machine comprising: a couch; and a gantry having a camera in communication with a server, wherein the server is configured to: present for display, in real time on a screen associated with the radiotherapy machine, images received from the camera, wherein when the gantry changes its orientation, the camera revises at least one of its orientations, such that images transmitted to the server maintain an original orientation.

A computer-implemented method of performing a treatment fraction of radiation therapy comprises: determining a current position of a target volume of patient anatomy; based on the current position of the target volume, computing an accumulated dose for non-target tissue proximate the target volume; determining that the accumulated dose is less than a current value for a dose budget of the non-target tissue; and in response to the accumulated dose being less than the current value for the dose budget, applying a treatment beam to the target volume while the target volume is in the current position.

Disclosed herein are radiotherapy methods and systems that can display a workflow-oriented graphical user interface(s). In an embodiment, a method comprises retrieving, by a server, information from a radiotherapy file associated with a patient, the information comprising an alignment data of at least a treatment region of the patient; presenting, by the server, for display on a graphical user interface, an image corresponding to the patient positioned on a couch of a radiotherapy machine, the image comprising an overlay on a surface of the patient in the treatment region; and presenting, by the server, for display, a visually distinct revised overlay for at least a portion of the surface of the patient in the treatment region that matches, within a predetermined margin of error, the alignment data.

Disclosed herein are radiotherapy systems and methods that can display a workflow-oriented graphical user interface(s). In an embodiment, a system comprises a radiotherapy machine comprising: a gantry having a screen in communication with a server, the screen configured to display a graphical user interface; and at least one camera, wherein the server is configured to present, in real time, images received from the at least one camera for display on a graphical user interface displayed on the screen.

Disclosed herein are radiotherapy systems and methods that can display a workflow-oriented graphical user interface(s). 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 method comprises presenting, by a server for display on a screen associated with a radiotherapy machine, a series of consecutive graphical user interfaces (GUIs), wherein a first GUI comprises: a first graphical indicator (GI) corresponding to a first attribute associated with configuration of the radiotherapy machine, and a second GI corresponding to a second attribute associated with the patient; when the server receives an indication that a user interacting with a pendant in communication with the server has inputted a first input corresponding to a first direction towards the first GI, presenting for display a second GUI comprising data associated with the first attribute; and when the server receives an indication that the user has inputted a second input corresponding to a second direction towards the second GI, presenting for display a third GUI comprising data associated with the second attribute.

Disclosed herein are radiotherapy methods and systems that can display a workflow-oriented graphical user interface(s). In an embodiment, a method comprises presenting, by the server for display on a screen associated with a radiotherapy machine, a series of consecutive graphical user interfaces, wherein each graphical user interface displays one or more graphical components corresponding to one or more tasks of one or more stages of a patient's radiotherapy treatment; and when a user operating the pendant interacts with a first controller of the pendant, the radiotherapy machine adjusts at least one of its configurations; and when the user interacts with a second controller of the pendant, the server revises the graphical user interface corresponding to the user's input.
