Devices, systems, and methods for combining and/or delivering an injectable material to a patient. The injectable material may be formed of two or more reactive components delivered in separate chambers. Various features are provided to reduce human error in combining the reactive components in the appropriate sequence to form the injectable material, generally at (e.g., immediately prior to) the time of delivery to a patient. The system includes a sleeve lock which facilitates coupling of a device having a first chamber containing a first component with a vial having a second chamber containing a second component to combine the first and second components. The combined first and second components are contained within the first chamber for delivery to a patient via an injection system, which may be fluidly coupled with the first chamber with the assistance of the sleeve lock.

The invention relates to a method of selecting a set of beam geometries for use in radiation therapy. The method (10) comprises providing (12) a plurality of candidate beam geometries; optimizing (1) a radiation treatment plan with all candidate beam geometries; and computing (14) a cost function value based on all candidate beam geometries. A first beam geometry from the plurality of candidate beam geometries is removed (15) and a first modified cost function value based on the candidate beam geometries without the removed first beam geometry computed (16). The first beam geometry is restored (17). The steps of removing a beam geometry, computing of a modified cost function value and restoring of the removed beam geometry are repeated (R) for all other candidate beam geometries. One or more beam geometries from the plurality of candidate beam geometries based on the modified cost function values are chosen (19).

According to an embodiment, a particle beam treatment system has: a CT device that is a three-dimensional image acquisition part installed in a treatment room for acquisition of a three-dimensional internal image on a day of treatment; a dose distribution display part that displays a dose distribution in the three-dimensional image acquired on the day of treatment and a dose distribution in treatment plan data designed in advance; a treatment management device that is a selection part to select whether or not to change the treatment plan data based on the dose distribution in the three-dimensional image acquired on the day of treatment and the dose distribution in treatment plan data designed in advance; and an irradiation part that irradiates an affected part with a particle beam according to the treatment plan data based on selection made by the treatment management device.

The invention discloses a grating device for radiotherapy equipment. A tail-end position controller and a front-end position controller are simultaneously arranged, and can simultaneously verify a tail-end position and a middle position of each single grating blade and measure the time during which one grating blade arrives at the middle position from the tail-end position and/or the total number of revolutions of a motor at any time. Because the distance between the tail-end position and the middle position is fixed and can be accurately measured, the system can accurately verify the position of one grating blade and control the grating blades to arrive at an accurately specified position; because the grating blades can be conveniently verified and controlled one by one, transmission errors caused by different grating blade driving systems and errors caused by instable performance can be effectively overcome; even verification can be performed before each fitting of a radiation field, and then accurate control can be realized according to the latest measured actual parameters.

An animal irradiation system includes a radioactive source and an irradiation fixing apparatus having irradiated bodies. The radioactive source includes a beam outlet having a first central axis. Radioactive rays generated by the radioactive source exit from the beam outlet and irradiate the irradiated bodies. The radioactive rays define a main axis around the first central axis. The irradiation fixing apparatus includes a box body, which is divided into multiple accommodating chambers around a second central axis. Each accommodating chamber accommodates an irradiated body. Multiple first irradiation holes corresponding to the accommodating chambers are formed on the box body. The radioactive rays pass through the first irradiation holes and then irradiate the irradiated bodies. A maximum distance from an inner wall of each first irradiation hole to the first central axis is less than a minimum distance from an inner wall of the beam outlet to the first central axis.

A neutron capture therapy apparatus includes a treatment unit including an irradiator irradiating an irradiation target with a neutron ray, a simulation unit simulating position adjustment of the target with respect to the irradiator in the treatment unit, a first moving mechanism capable of moving the target in the treatment unit, a second moving mechanism capable of moving the target with respect to the simulation unit, and a transport mechanism capable of transporting the target from the second moving mechanism to the first moving mechanism, in which the second moving mechanism moves the target such that a target position with respect to the simulation unit is substantially the same as a predetermined target position with respect to the irradiator in the treatment unit, and the first moving mechanism moves the target to the predetermined target position with respect to the irradiator in the treatment unit.

A radiation suite includes a room having a floor, a ceiling, and one or more walls, a radiation system including a gantry enclosing a radiation source and a couch, and an image projection system operable to project an image on a projection surface on at least a portion of the gantry and/or the couch, providing a calming environment for a patient to relax. The image projection system comprises a computer and one or more projectors operably controlled by the computer. The computer comprises a mapping software operable to map an image file to the projection surface. The one or more projectors are operable to project the mapped image file on the projection surface.

Toroidal superconducting magnets can be used as lightweight rotating bending magnets in hadron therapy gantries. The toroidal bending magnets are self-shielded and do not require ferromagnetic material for field modification or shielding, decreasing both the magnet system weight, as well as overall gantry weight. Achromatic magnet can be made by combining two of these bending magnets. The simple geometry may allow the use of higher fields, making it attractive for carbon, as well as proton.

A radiation treatment apparatus is described. The radiation treatment apparatus may include a gantry frame and a rotatable gantry structure rotatably coupled to the gantry frame, the rotatable gantry structure being rotatable around a rotation axis passing through an isocenter, with the rotatable gantry structure including a first beam member extending between first and second ends of the rotatable gantry structure. The radiation treatment apparatus may also include a radiation treatment head movably mounted to the first beam member in a manner that allows (i) translation of the radiation treatment head along the first beam member between the first and second ends, and (ii) gimballing of the radiation treatment head relative to the first beam member, the gimballing being characterized by pivotable movement in at least two independent pivot directions defined with respect to the first beam member. Non-coplanar radiation treatment of a tissue volume positioned near or around the isocenter may be achievable with the radiation treatment apparatus.
