The present invention makes it possible to provide a radiation therapy system capable of not only inhibiting treatment time from increasing more effectively than before but also reducing the loads of fluoroscopic radiation photographing apparatuses. The radiation therapy system has: a therapeutic radiation irradiation apparatus to irradiate a target with therapeutic radiation; two fluoroscopic radiation photographing apparatuses to photograph the target simultaneously from two directions; a target position computation apparatus to compute a three-dimensional position of the target on the basis of photographed fluoroscopic images; a therapeutic radiation irradiation control apparatus to control the irradiation of the therapeutic radiation on the basis of the computed three-dimensional position of the target; and a fluoroscopic radiation photographing control apparatus to control irradiation quantities per unit time of the fluoroscopic radiation photographing apparatuses on the basis of the three-dimensional position of the target.

The present invention relates to a radiotherapy apparatus and a method for determining target positions using a radiotherapy apparatus, so as to accurately detect the motion of the tumor position. The method includes: a ray source locating in a first position, and emitting a radiation beam; a detector receiving the radiation beam emitted by the ray source at the first position, and generating first image data of the target according to the radiation beam emitted by the ray source at the first position; the ray source moving to a second position and emitting a radiation beam, wherein an interval at which the ray source moves from the first position to the second position is a positive integer multiple of a preset breathing cycle of a patient; the detector receiving the radiation beam emitted by the ray source at the second position, and generating second image data of the target according to the radiation beam emitted by the ray source at the second position; and determining position information of the target according to the first image data and the second image data.

Disclosed herein are radiotherapy systems and methods that can display a workflow-oriented graphical user interface(s). In an embodiment, a system comprises a radiotherapy machine comprising: a couch; and a gantry having a camera in communication with a server, wherein the server is configured to: present for display, in real time on a screen associated with the radiotherapy machine, images received from the camera, wherein when the gantry changes its orientation, the camera revises at least one of its orientations, such that images transmitted to the server maintain an original orientation.

Systems and methods for implementing an adaptive therapy workflow that minimizes time needed to create a session patient model, select an appropriate plan for the treatment session, and treat the patient.

A patient-positioning device and a medical workstation including the patient-positioning device. The patient-positioning device includes a patient couch and a robot arm which is provided for moving the patient couch and which comprises several links arranged one after another and mounted rotatably with respect to axes. The robot arm includes, as links, a start link, a first link, a second link, a third link, a fourth link, a fifth link and a sixth link. The robot arm comprises a patient couch or a fastening device on which the patient couch is fastened.

The present disclosure provides a subject support apparatus for a radiation therapy device comprising a base, a subject support tillable relative to the base, at least two first guides disposed between the subject support and the base and each inclined relative to the base, and a tilting module. The tilting module comprises a first actuator, and a plate disposed between the subject support and the base, and the plate is coupled to an underside of the subject support and to the first actuator such that movement generated by the first actuator is translated into movement of the plate along the at least two first guides, thereby causing the subject support to tilt relative to the base.

A medical imaging system a magnet unit includes a main magnet and a first housing. In an embodiment, the main magnet is arranged inside the first housing and includes coil elements and at least one coil carrier, the magnet unit defining an examination opening. The first radiation unit is embodied to irradiate the examination object and is arranged on the side of the magnet unit. The magnet unit includes a first region, transparent to radiation emitted by the first radiation unit radially to the examination axis. The first radiation unit is embodied to emit radiation through the first region of the magnet unit in a direction of the examination opening and is furthermore embodied to rotate about the examination opening.

The present disclosure is directed to a radiation therapy system. The radiation therapy system may comprise a magnetic resonance imaging (MRI) apparatus configured to acquire MRI data with respect to a region of interest (ROI) of a subject, the MRI apparatus including a magnetic body; and a radiation therapy apparatus configured to apply a radiation beam to at least one portion of the ROI. The radiation therapy apparatus may include a linear accelerator configured to accelerate electrons to produce the radiation beam, the linear accelerator being located in a bore formed by an inner surface of the magnetic body, and a length direction of the linear accelerator being parallel with an axis of the magnetic body.

Systems, methods, and computer software are disclosed that allow the automatic recalling of imaging parameters from computer memory for controlling an MRI system to perform treatment-day scans of a patient on a treatment couch in a radiotherapy system, prior to treatment. The treatment-day scans can be automatically initialized and the MRI system can then be controlled to perform the treatment-day scans according to the recalled imaging parameters. Reoptimized radiation treatment plan(s) can be automatically generated and predicted doses to anatomical structures of the patient based on the plan(s) can be displayed. Clinicians can be enabled to perform numerous reoptimization tasks simultaneously through parallel workflow interfaces and then a radiation therapy device can be controlled to deliver radiation according to a selected radiation treatment plan.

Disclosed are an oral fixation device for radiation therapy and an oral fixation method in treatment of a lip cancer. The oral fixation device for radiation therapy includes a first spacer including a first insert inserted between a first lip portion and a first gum portion, and a tooth support coupled to the first spacer at a side of the first spacer disposed inwardly of an oral cavity, wherein teeth or gums of a patient is supported on the tooth support, wherein a first spacer has a specific thickness to maintain a specific spacing between the first lip portion and the first gum portion, wherein the first lip portion includes a treatment target portion to be subjected to the radiation therapy.
