摘要： A method for determining a deformation measurement of a couch in a medical procedure may include determining a first deformation measurement of the couch at a reference point, the first deformation measurement corresponding to a first working position of the couch. The method may also include determining a second deformation measurement of the couch at the reference point, the second deformation measurement corresponding to a second working position of the couch. The method may further include determining a difference between the first deformation measurement and the second deformation measurement and causing an adjustment of one of the first working position and the second working position of the couch based on the difference between the first deformation measurement and the second deformation measurement.

摘要： Embodiments of the present disclosure provide a radiotherapy system, comprising a first imaging component, a second imaging component, and a treatment component. The first imaging component and second imaging component may be used to determine a target region of an object and/or to guide an emission of treatment rays. The treatment component may be used to emit the treatment rays toward the target region. An isocenter of the treatment component may coincide with an isocenter of the second imaging component.

摘要： The present disclosure relates to a radiation treatment system. The radiation treatment system may include an MLC having at least one layer of leaves and at least one block. Each of the at least one layer of leaves may include a first group of leaves and a second group of leaves. At least a portion of the leaves may be movable to block pathways of a first portion of the radiation beams within a radiation area. A second portion of the radiation beams may be incident at a treatment region of the radiation treatment system. The MLC may be situated in a first plane. The at least one block may be situated in a second plane different from the first plane. The at least one block may be configured to shield at least a portion of leaking radiation beams within an end area.

摘要： A radiation system is provided. The radiation system may include a bore accommodating an object, a rotary ring, a first radiation source and a second radiation source mounted on the rotary ring and a processor. The first radiation source may be configured to emit a first cone beam toward a first region of the object. The second radiation source may be configured to emit a second beam toward a second region of the object, the second region including at least a part of the first region. The processor may be configured to obtain a treatment plan of the object, the treatment plan including parameters associated with radiation segments. The processor may be further configured to control an emission of the first cone beam and/or the second beam based on the parameters associated with the radiation segments to perform a treatment and a 3-D imaging simultaneously.
