An x-ray treatment system includes an electron beam generator configured to generate an electron beam and an x-ray treatment head comprising an array of pixel source cells including side walls defining an x-ray transmissive interior. The side walls include an x-ray absorptive material. A target element is positioned to, when impacted by the electron beam, generate x-ray photon radiation within the x-ray transmissive pixel source cell interior. An electron beam control system includes a controller configured to control responsive to a treatment plan at least one of the direction and intensity of the electron beam to a particular one of the pixel source cells, and then responsive to the treatment plan to control at least one of the direction and intensity of the electron beam to at least one additional pixel source cell. A method of treating a patient with x-ray photon radiation is also disclosed.

An intraoral positioning device (IPD) is disclosed for positioning in a patient's mouth for radiation therapy planning and treatment, the device comprising an engagement member configured to engage structure within a patient's mouth during radiation planning or treatment, wherein the engagement member includes an upper wall, a lower wall and first and second side walls extending from and between the upper and lower walls, whereby the upper, lower and first and second side walls form top, bottom, front and rear walls of a bite block, and a handle extending from the engagement member to enable a user to grasp the IPD for introducing and removing it from the patient's mouth.

Disclosed herein is a method of positioning a patient for radio-therapy treatment using a radiotherapy device. The method comprises determining an identity of a treatment beam that is to be used to treat the patient, determining an offset between a reference location and an isocentre location for the identified treatment beam that is to be used to treat the patient, and changing a spatial relationship between the patient and at least a part of the radiotherapy device, according to the determined offset.

The present relates to a device for providing a radiation treatment to a patient comprising:—an electron source for providing a beam of electrons, and—a linear accelerator for accelerating said beam until a predetermined energy, and—a beam delivery module for delivering the accelerated beam from said linear accelerator toward the patient to treat a target volume with a radiation dose, The device further comprises intensity modulation means configured to modulate the distribution of the radiation dose in the target volume according to a predetermined pattern. The pattern is determined to match the dimensions of a target volume of at least about 50 cm.sup.3, and/or a target volume located at least about 5 cm deep in the tissue of the patient with said radiation dose, The radiation dose distributed is up to about 20 Gy delivered during an overall treatment time less than about 50 ms.

A method for adjusting a medical device is provided. The method includes obtaining an initial trajectory of a component of the medical device. The initial trajectory of the component includes a plurality of initial positions. For each of the plurality of initial positions, the method further includes determining whether a collision is likely to occur between a subject and the component according to the initial trajectory of the component. In response to the determination that the collision is likely to occur, the method further includes updating the initial trajectory of the component to determine an updated trajectory of the component.

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.

A fastener applicator includes a body portion including a handle assembly, a cartridge assembly supported within the body portion, the cartridge assembly including implantable fasteners, a drive assembly supported within the body portion and operatively coupled to the cartridge assembly to engage the implantable fasteners, and an actuation assembly supported within the handle assembly and operatively coupled to the drive assembly to fire a distal-most implantable fastener upon actuation of the actuation assembly. At least one of the implantable fasteners includes a body including a tissue facing surface, a tissue penetrating portion extending from the body, and a capsule affixed to the tissue facing surface of the body, the capsule including radioactive material.

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.
