A combined MRI and radiotherapy apparatus comprises a radiotherapeutic source, an MRI system, a patient support, drive motors for the patient support arranged to adjust the position of the patient support while a patient is on the support, a control panel having a user-operable input interface for controlling the drive motors, and a display unit. A mounting arrangement for a display device comprises a transparent cover, a display panel held against a rear face of the cover so as to be visible through a front face of the cover, and a retaining structure for holding the display panel in place. The retaining structure comprises a chassis fixable in position relative to the cover, the chassis having at least one resilient finger extending therefrom alongside a rear face of the display panel, a part of which bears against the rear face of the display panel to resiliently urge the display panel against the rear face of the cover. The radiotherapeutic source, MRI system, patient support and the control panel will usually be located within an enclosed space, to confine the therapeutic radiation; a second control panel is provided outside the enclosed space, able to control at least the radiotherapy source.

There is provided a patient's cranial position monitoring and controlling device for controlling a magnetic resonance (MR) guided radiation source module via an MR-guided radiation controlling device connected to the patient's cranial position monitoring and controlling device and an MR-guided radiation system including a patient's cranial position monitoring and controlling device, which allows for better MR-imaging while allowing patient position monitoring close to the patient.

An interventional therapy system may include at least one catheter configured for insertion within an object of interest (OOI); and at least one controller which configured to: obtain a reference image dataset including a plurality of image slices which form a three-dimensional image of the OOI; define restricted areas (RAs) within the reference image dataset; determine location constraints for the at least one catheter in accordance with at least one of planned catheter intersection points, a peripheral boundary of the OOI and the RAs defined in the reference dataset; determine at least one of a position and an orientation of the distal end of the at least one catheter; and/or determine a planned trajectory for the at least one catheter in accordance with the determined at least one position and orientation for the at least one catheter and the location constraints.

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 neutron capture therapy apparatus includes a neutron beam irradiation system, a detection system and a monitoring system. The neutron beam irradiation system is configured for generating a neutron beam. The detection system is configured for detecting real-time irradiation parameters during a neutron beam irradiation therapy process. The monitoring system is configured for controlling the whole neutron beam irradiation process and includes an input part for inputting preset irradiation parameters, a determination part for determining whether the irradiation parameters need to be corrected and a correction part for correcting some of the irradiation parameters when the determination part determines that the irradiation parameters need to be corrected. When the ratio of the real-time neutron dose detected by the detection system to a preset neutron dose is greater than or equal to a preset value, the determination part of the monitoring system determines that the irradiation parameters need to be corrected.

A method for planning a scan path for intraoperative radiation therapy may comprise acquiring a plurality of images of a region of interest through an auxiliary scanning component, establishing a 3D model of the region of interest based on the plurality of images of the region of interest, determining a radiation therapy volume based on the 3D model of the region of interest, and planning a scan path for a radiation therapy component to scan the radiation therapy volume.

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.

To enable an appropriate and quick detection of a change in an internal structure of a patient, a computer program causes a computer to detect a change in an internal structure of a patient. The process includes calculating a second water equivalent thickness obtained from a second three-dimensional image being a three-dimensional image of a patient, which is newly obtained; a process of calculating a change of a first water equivalent thickness from the second water equivalent thickness, the first water equivalent thickness being obtained from a first three-dimensional image being a three-dimensional image of the patient in treatment planning; and a process of calculating a dose volume histogram change for calculating a change in a dose volume histogram from the treatment plan, based on the calculated water equivalent thickness change and correlation information indicating a correlation between a water equivalent thickness change value and dose distribution information.

A method for treating a tumor, comprising identifying a tumor as a colon cancer tumor and implanting in the tumor identified as a colon cancer tumor, as least one diffusing alpha-emitter radiation therapy (DaRT) source with a suitable radon release rate and for a given duration, such that the source provides during the given duration a cumulated activity of released radon between 3.5 Mega becquerel (MBq) hour and 8.4 MBq hour, per centimeter length.

Parameterized model reconstruction is used for internal dose tomography. The parameterized model, solved for within the reconstruction, models the dose level and may account for diffusion, isotope half-life, and/or biological half-life. Using the detected emissions from different scans (e.g., from different scan sessions in a given cycle) as input for the one reconstruction, the parameterized model reconstruction determines the biodistribution of dose at any time.
