Disclosed herein are radiotherapy methods and systems that can display a workflow-oriented graphical user interface(s). A method comprises presenting a plurality of pages for display, each corresponding to a stage of a radiotherapy treatment for a patient; in response to receiving an indication that a surface of a patient is aligned, retrieving, from a radiotherapy file, a first image of an internal target aligned in accordance with treatment attributes; receiving a second image of the internal target; overlaying on a first page of the plurality of pages, the first image and the second image, the first page displaying a direction to position the internal target in the second image to align with the internal target in the first image; and when the internal target is aligned, presenting for display a second page of the plurality of pages corresponding to a subsequent stage of the radiotherapy treatment for the patient.

A magnetic resonance (MR)-radiotherapy (RT) hybrid system for treating a patient is disclosed. The MR-RT hybrid system comprises: an MR imaging (MRI) apparatus comprising bi-planar magnets configured to generate a magnetic field; a radiation source configured to supply a radiation beam to treat the patient; a gantry configured to couple the MR apparatus at a first end and the radiation source so that they can rotate in unison; a treatment support configured to support the patient; a motor configured to move the treatment support; and a controller. The controller comprises a processor and memory having stored thereon instructions, which when executed by the processor, cause the motor to move the treatment support in order to avoid collision between the MRI apparatus and the patient when the MRI apparatus is rotated. A method for positioning the treatment support within the MR-RT hybrid system is also disclosed.

Information associated with a radiation treatment plan includes, for example, values of dose per voxel in a target volume, values of dose rate per voxel in the target volume, and values of parameters used when generating the values of dose per voxel and the values of dose rate per voxel. Renderings that include, for example, a rendering of an image of or including the target volume, and a rendering of selected values of the radiation treatment plan, are displayed. When a selection of a region of one of the renderings is received, a displayed characteristic of another one of the renderings is changed based on the selection.

Described herein are systems and methods for positioning a radiation source with respect to one or more regions of interest in a coordinate system. Such systems and methods may be used in emission guided radiation therapy (EGRT) for the localized delivery of radiation to one or more patient tumor regions. These systems comprise a gantry movable about a patient area, where a plurality of positron emission detectors, a radiation source are arranged movably on the gantry, and a controller. The controller is configured to identify a coincident positron annihilation emission path and to position the radiation source to apply a radiation beam along the identified emission path. The systems and methods described herein can be used alone or in conjunction with surgery, chemotherapy, and/or brachytherapy for the treatment of tumors.

Disclosed herein are systems and methods for identifying radiation therapy treatment data for different patients, such as field geometry. A central server collects patient data, radiation therapy treatment planning data, clinic-specific rules, and other pertinent treatment/medical data associated with a patient. The server then executes one or more machine-learning computer models to predict field geometry variables and weights associated with the patient's treatments. Using the predicted variables and weights, the server execute a clinic-specific set of logic to identify suggested field geometry, such as couch/gantry angles and/or arc attributes. The server then monitors whether end users (e.g., medical professionals) revise the suggested field geometry and trains the model accordingly.

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 a server, for display on a graphical user interface, an image of a position of a patient on a couch of a radiotherapy machine, whereby at least a gantry of the radiotherapy machine is configured to rotate around the patient; calculating, by the server, one or more predicted collisions between a part of the radiotherapy machine and at least one of (a) the patient or (b) another part of the radiotherapy machine; and when a portion of the patient is calculated to be in a collision with the part of the radiotherapy machine, revising, by the server, the graphical user interface such that the portion of the patient calculated to be in the collision is visually distinct in the image.
