The present disclosure provides methods of treating a biological tissue using a proton beam. A method includes the steps of: irradiating a proton beam to a biological tissue containing a reactant. The reactant includes a composite. The composite reacts with at least one proton from the proton beam and releases at least one particle or rays. The particle or rays reacts with the biological tissue. Another method includes the steps of: providing a reactant, the reactant comprising a composite; introducing the reactant into a biological tissue, the reactant being distributed in the biological tissue; and irradiating the biological tissue with the proton beam. The composite reacts with at least one proton from the proton beam to release at least one particle or rays, and the particle or the rays reacts with the biological tissue.

A system for particle beam therapy has an adjustable gantry for beam delivery to a patient site. The gantry has a beam coupling section, a first beam bending section with beam deflection and/or focusing magnets. A beam transport section receiving the particle beam from the first beam bending section and guiding the particle beam to a second beam bending section. The beam exits at a window of a beam nozzle. A patient table/chair is rotatable in the horizontal plane or in a plane being parallel to the horizontal plane and optionally being adjustable vertically. The gantry is supported by a tilting mechanism allowing the gantry to be tilted vertically by an angle 1[90; +90]. A rotation mechanism is disposed in a way that the second beam bending section and the beam nozzle are rotatable by an angle 2[180; +180] around a direction given by the angle 1.

A device for surface brachytherapy includes a base configured for positioning a source with respect to a target area, an aperture defined in the base, and a shield body configured for coupling with the base, so that the source is secured within the base proximate or adjacent the aperture. The aperture is configured to transmit radiation emitted by the source, where the radiation is directed toward the target area. The base and shield body are configured to absorb at least a portion of the radiation emitted by the source, where the radiation is not directed toward the target area.

The present invention relates to an ophthalmic treatment apparatus and a control method therefor, and provides an ophthalmic treatment apparatus and a control method therefor, the ophthalmic treatment apparatus comprising: a setting unit formed so as to set a treatment mode; a therapeutic light emission unit emitting therapeutic light at a target position of an eyeground multiple times so as to perform treatment; a monitoring unit for monitoring information on the state of the target position by the therapeutic light during the emission of the therapeutic light; and a control unit for determining whether a treatment intensity according to the treatment mode has been reached, by using the information monitored by the monitoring unit, and for controlling an operation of the therapeutic light emission unit on the basis of the determination.

A radiotherapy center includes a treatment room and a radiation machine located in the treatment room. The treatment room is constructed with materials comprising a plurality of prefabricated, modular radiation shielding blocks.

Presented systems and methods facilitate efficient and effective generation and delivery of radiation. In one embodiment, an accelerator system includes a particle source, an acceleration portion, a high intensity target, and a target location control component. The particle source is configured to generate charged particles. The acceleration portion is configured to accelerate the charged particles. The high intensity target is configured to generate Bremsstrahlung radiation in response to impact by the charged particles. The target location control component configured to change the location of charged particle impacts on the high intensity target. In one exemplary implementation the change of location of charged particle impact is based on thermal diffusion and said location of charged particle impacts is moved at a rate greater than a rate of diffusion of detrimental heat impacts on the high intensity target.

Radiation therapy devices, systems and methods are in general sheet-like form, are characterized by flexibility, and include at least one spacer that can be a balloon or bubble that assists in placement of radio therapeutic members at desired treatment locations along or around a limb, within an existing body cavity, or at a site that was formed under a patient's skin for treatment purposes. Sarcoma treatment is particularly conducive to treatment by these devices, systems and methods. One or more detectors, such as microdiodes, are accommodated when desired on the device, and a hyperthermia tube or the like is also includable that delivers hyperthermia treatment for the target treatment site or sites. Data collected by the detector allows the medical professional to monitor radiation treatment and, when desired, interaction between hyperthermia treatment and radiation delivery by the radiation treatment member.

A method for radiotherapy may include generating an electrical impedance tomography (EIT) image of a patient. The method may also include generating a first image. The method may further include determining an EIT feature of the EIT image. The method may also include determining a position relationship between the EIT image and the first image. The method may further include locating an anatomical structure of interest (ASI) of the patient based on the position relationship. The method may further include delivering radiation to the ASI of the patient.
