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 a server, a graphical user interface for display on a screen associated with a radiotherapy machine, wherein the graphical user interface contains a page corresponding to one or more stages of radiotherapy treatment for the patient, and transitioning, by the server, the graphical user interface from a first page representing a first stage to a second page representing a second stage provided that at least a predetermined portion of tasks associated with the first stage has been satisfied.

A system and method for adapting treatment plan are provided. The method may include: obtaining a planning image of a region of interest relating to a first treatment fraction of a first treatment plan; obtaining a first image of the region of interest relating to a first scan of the region of interest with a first dose level; comparing the planning image with the first image to generate a first comparison result; determining whether the first comparison result satisfies a first replanning condition; causing, in response to a determination that the first comparison result satisfies the first replanning condition, one or more scanners to perform a second scan with a second dose level to provide a second image; and generating a second treatment plan according to the second image, wherein the second dose level is higher than the first dose level.

Disclosed herein are systems and methods for identifying radiation therapy treatment data for patients. A processor accesses a neural network trained based on a first set of data generated from characteristic values of a first set of patients that received treatment at one or more first radiotherapy machines. The processor executes the neural network using a second set of data comprising characteristic values of a second set of patients receiving treatment at one or more second radiotherapy machines. The processor executes a calibration model using an output of the neural network based on the second set of data to output a calibration value. The processor executes the neural network using a set of characteristics of a first patient to output a first confidence score associated with a first treatment attribute. The processor then adjusts the first confidence score according to the calibration value to predict the first treatment attribute.

Various approaches for enhancing treatment of target tissue using a source of focused ultrasound while limiting damage to non-target tissue include selecting a frequency of ultrasound waves transmitted from the source of focused ultrasound for generating a focus in the target tissue; providing microbubbles having the first size distribution such that at least 50% of the microbubbles have a radius smaller than a critical radius corresponding to a resonance frequency matching the selected frequency of ultrasound waves; and applying the ultrasound waves at the selected frequency to treat the target tissue.

Apparatus for performing a procedure at a target site of a patient's body, the apparatus comprising: a continuous positive airway pressure (CPAP) apparatus that provides CPAP to the patient's lungs; a medical device for performing the procedure at the target site; and a controller that controls the CPAP apparatus to provide CPAP to the patient's lungs during performance of the procedure.

A method of controlling a radiotherapy device, a computer readable medium and a radiotherapy device are disclosed. The radiotherapy device includes a radiation source coupled to a rotation means. The method includes applying radiation to a subject using the radiation source and rotating the radiation source around the subject using the rotation means according to a first fixed rotation scheme. The method further includes, during execution of the first fixed rotation scheme, determining that the subject is in a suboptimal position, pausing application of the radiation by the radiation source and logging a first angle of rotation of the radiation source at which application of the radiation is paused.

A multi-mode cone beam computed tomography radiotherapy simulator and treatment machine is disclosed. The radiotherapy simulator and treatment machine both include a rotatable gantry on which is positioned a cone-beam radiation source and a flat panel imager. The flat panel imager captures x-ray image data to generate cone-beam CT volumetric images used to generate a therapy patient position setup and a treatment plan.

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.

A positional pattern of an irradiation unit for irradiating a patient with treatment radiation is determined based on optimal order data describing an order of the irradiation unit positions for which the statistical value is optimal. The optimal order data is determined based on irradiation unit position data describing irradiation unit positions of the irradiation unit for which the imaging device has a free viewing direction onto the position of the patient, position orders data describing all possible orders of the irradiation unit positions for which the imaging device has a free viewing direction onto the position of the patient, and intersection angle data describing a statistical quantity of the intersection angles between free viewing directions of the imaging unit for irradiation unit positions which are immediately subsequent in the order described by the position orders data.
