    摘要: A jaw assembly and a medical accelerator are provided. The jaw assembly includes: a jaw base, a moving assembly and at least one set of jaws, each set of jaws including at least two jaw bodies. The jaw base is detachably connected to a mounting seat of a treatment head beam shaping module of a medical accelerator, and when the jaw base is mounted on the mounting seat, a beam opening formed is located under the treatment head beam shaping module. The jaw body is connected to the jaw base through the moving assembly, and the moving assembly is configured to move the jaw body to between the beam opening and the treatment head beam shaping module, or to move the jaw body out between the beam opening and the treatment head beam shaping module to adjust a beam flow through the beam opening.

    摘要: Devices, systems and method that allow for delivery of therapeutic radiation beams of differing sizes or shapes during a radiation treatment are provided herein. Such devices can include a rotatable collimator body having multiple collimator channels of differing size or shape defined therein, the channels extending through the collimator body substantially perpendicular to the axis of rotation. The collimator body can include markers thereon to facilitate detection of an alignment position by a sensor of a control system to allow the collimator body to be rapidly and accurately moved between alignment positions to facilitate delivery of differing therapy beams during a treatment.

    摘要: The invention discloses a radiation field control device and radiotherapy equipment. Two or more different-sized light limiting barrels are directly machined on a light limiting barrel support, or two or more light limiting barrel mounting portions are arranged on the light limiting barrel support, then the two or more light limiting barrels are respectively mounted in the light limiting barrel mounting portions in a one-to-one correspondence manner, any one of the light limiting barrels can move to a working position through a light limiting barrel switching device, in this case, when the light limiting barrel having suitable size is required, the unsuitable light limiting barrel does not need to be detached, and the required light limiting barrel can be used conveniently and quickly by directly controlling the light limiting barrel switching device. By adopting the solution, the radiation field control device is not only simple in structure, convenient and quick to use, but also greatly improves the working efficiency.
