A graphical user interface is configured for display on a computer display. The graphical user interface includes a dose rate slider configured to enable a user to select a range of radiation dose rates of a radiotherapy plan, and a display image configured to present an image. The dose rate slider may be selectable among less than a value of the dose rate slider, and more than a value of the dose rate slider.

A control circuit generates an optimized radiation treatment plan with respect to an adjustable collimation device and then automatically generates at least one quality assurance accuracy value corresponding to the optimized radiation treatment plan. By one approach, the aforementioned plan comprises a plurality of treatment fields. In such a case, automatically generating at least one quality assurance accuracy value can comprise, at least in part, automatically generating at least one quality assurance accuracy value for each of at least a substantial number (or all) of those treatment fields. By one approach, the aforementioned quality assurance accuracy value comprises a dimensionless metric. This dimensionless metric may represent, for example, dosimetric accuracy corresponding to the optimized radiation treatment plan.

Disclosed herein are methods and systems to optimize a radiation therapy treatment plan using dose distribution values predicted via a trained artificial intelligence model. A server trains the AI model using a training dataset comprising data associated with a plurality of previously implemented radiation therapy treatments on a plurality of previous patients and dose distributions associated with one or more organs of each previous patient. The server then executes the trained AI model to predict dose distribution for a patient. The server then displays a heat map illustrating the predicted values, transmits the predicted values to a plan optimizer to generate an optimized treatment plan for the patient, and/or transmits an alert when a treatment plan generated by a plan optimizer deviates from rules and thresholds indicated within the patient's plan objectives.

Images obtained by a camera system (10) arranged to obtain images of a patient (20) undergoing radio-therapy are processed by a modeling unit (56,58) which generates a model of the surface of a patient (20) being monitored. Additionally the patient monitoring system processes image data not utilized to generate a model of the surface of a patient being monitored to determine further information concerning the treatment of the patient(20). Such additional data can comprise data identifying the relative location of the patient and a treatment apparatus (16). This can be facilitated by providing a number or retro-reflective markers (30-40) on a treatment apparatus (16) and a mechanical couch (18) used to position the patient (20) relative to the treatment apparatus (16) and monitoring the presence and location of the markers in the portions of the images obtained by the stereoscopic camera (10).

A motion-enable device includes a mechanical switch and a capacitive sensor with a sensing region that is located adjacent to the mechanical switch. The mechanical switch enables a first signal when closed or actuated that indicates that the mechanical switch is in an active state. The capacitive sensor enables a second signal when a conductive object is disposed in the sensing region, where the second signal indicates that the capacitive sensor is in an active state. Enablement of operation of an apparatus depends on receipt of both the first signal and the second signal. The mechanical switch and the capacitive sensor act as the two separate switches required by functional safety requirements for a motion enable device. Because the sensing region of the capacitive sensor is adjacent to the mechanical switch, the first and second signals are generated when an operator actuates the mechanical switch with a single digit.

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.

The invention relates to a method and apparatus for control of a charged particle cancer therapy system. A treatment delivery control system is used to directly control multiple subsystems of the cancer therapy system without direct communication between selected subsystems, which enhances safety, simplifies quality assurance and quality control, and facilitates programming. For example, the treatment delivery control system directly controls one or more of: an imaging system, a positioning system, an injection system, a radio-frequency quadrupole system, a ring accelerator or synchrotron, an extraction system, a beam line, an irradiation nozzle, a gantry, a display system, a targeting system, and a verification system. Generally, the control system integrates subsystems and/or integrates output of one or more of the above described cancer therapy system elements with inputs of one or more of the above described cancer therapy system elements.

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.
