A treatment planning system that generates treatment planning for irradiating a target with a particle beam, includes an arithmetic processing device that sets at least two or more irradiation patterns for one treatment planning, calculates a plurality of predicted dose distributions for each irradiation pattern based on a target dose set for each region for at least one region including a region of the target, and calculates an index for evaluating validity of the irradiation pattern based on the plurality of predicted dose distributions.

According to an embodiment, a medical image processing device includes a first image acquirer, a second image acquirer, a direction acquirer, and a movement amount calculator. The first image acquirer acquires a three-dimensional first image obtained by photographing the inside of a body of a patient. The second image acquirer acquires a three-dimensional second image of the inside of the body of the patient imaged at a timing different from that of the first image. The direction acquirer acquires information about an irradiation direction of radiation to the patient in a treatment room. The movement amount calculator outputs a movement amount signal indicating the amount of movement of the second image to be moved to align the position of the patient shown in the second image with the position of the patient shown in the first image based on the path of the radiation set in the first image and the information about the irradiation direction.

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.

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 positioned on a gantry of a radiotherapy machine, wherein the graphical user interface comprises a page corresponding to a radiotherapy treatment of a patient, wherein the page comprises a first graphical element indicating at least one attribute of alignment data corresponding to the radiotherapy treatment of the patient.

A base dose calculation tool for determining a base dose employed in treatment planning. Base therapy information is considered on a voxelized and temporal basis such that subsequent treatments may be planned. The base dose output is operable with existing treatment planning systems.

Methods and systems are provided which relate to the planning and delivery of radiation treatments by modalities which involve moving a radiation source along a trajectory relative to a subject while delivering radiation to the subject. An artificial intelligence (AI) agent trained using reinforcement learning (and/or some other suitable form of machine learning) is used to control the radiation delivery parameters in effort to achieve desired delivery of radiation therapy. In some embodiments, the AI agent selects suitable control steps (e.g. radiation delivery parameters for particular time steps), while accounting for patient motions, difference(s) in patient anatomical geometry and/or the like.

An example computer-implemented method for tuning a beam spot in a radiation therapy system based on radiation field measurements has been disclosed. The example method includes configuring an electron beam to generate a first beam spot on an electron-beam target of the radiation therapy system, determining a value for one or more radiation field quality metrics for a first radiation beam that originates from the first beam spot, and based on the value, determining whether the first radiation beam is outside a specified quality range.

Disclosed are a neutron capture therapy apparatus and an operation method of a monitoring system thereof. The neutron capture therapy apparatus includes a neutron beam irradiation system, a measurement system and a monitoring system. The neutron beam irradiation system is used for generating a neutron beam suitable for carrying out neutron irradiation therapy on a sick body, the measurement system is used for measuring real-time irradiation parameters during a neutron beam irradiation therapy process, and the monitoring system is used for controlling the whole neutron beam irradiation process. The monitoring system includes an input section for inputting preset irradiation parameters, a storage section for storing the irradiation parameters, a modification section for modifying some of the irradiation parameters in the storage section, and a display section for displaying the irradiation parameters in real time.

An example method of radiation therapy in a radiation therapy system that includes a gantry with a treatment-delivering X-ray source and an imaging X-ray source mounted thereon is described. The method includes rotating the gantry in a first direction at a first rotational velocity about an open bore and concurrently rotating an annular support structure at a second rotational velocity about the open bore, wherein the second rotational velocity is less than the first rotational velocity. While continuing to rotate the gantry in the first direction about the open bore from a first position to a treatment position, the method also includes generating multiple images of a target volume disposed in the bore using the imaging X-ray source. Upon rotating the gantry to the treatment position, the method includes initiating delivery of a treatment beam to the target volume with the treatment-delivering X-ray source.

An intervention system employing an interventional device (10), and a sensor wire (20) manually translatable within the lumen (11). The intervention system further employs a reconstruction controller (44) for reconstructing a shape of the interventional tool (10) responsive to a sensing of a manual translation of the sensor wire (20) within the lumen (11) (e.g., a EM sensor being attached to/embedded within a guide wire), and for determining a reconstruction accuracy of a translation velocity of the sensor wire (20) within the lumen (11) to thereby facilitate an accurate reconstruction of the shape of the interventional tool (10). The reconstruction accuracy may be determined by the reconstruction controller (44) as an acceptable translation velocity being less than an acceptable threshold, an unacceptable translation velocity being greater than an unacceptable threshold, and/or a borderline translation velocity being greater than the acceptable threshold and less than the unacceptable threshold. The reconstruction controller (44) generates an acceptability indicator that may be visualizing or audibly communicated via a user interface (48).
