    摘要： The present disclosure generally relates to a multi-leaf collimator. The multi-leaf collimator may include a set of leaves installed in a cavity, each leaf of the set of leaves having a length along a first direction. At least a portion of the set of leaves may extend beyond the cavity along the first direction. The set of leaves may be arranged along a second direction, the second direction being different from the first direction. A length of a target leaf of the set of leaves may be less than a length of a reference leaf of the set of leaves. The target leaf may be located in an end portion of the set of leaves along the second direction. The length of the set of leaves may conform to the shape of a maximum therapeutic radiation field.

    摘要： The present disclosure is related to systems and methods for generating a radiation treatment plan for a treatment volume of a subject. The method includes retrieving a planning image of the treatment volume. The planning image may include a plurality of first voxels. The method also includes retrieving a treatment image that represents at least part of the treatment volume. The treatment image may include a plurality of second voxels. For at least one of the plurality of second voxels, the method further includes determining at least one reference voxel among the plurality of first voxels in the planning image and determining a dose value corresponding to the at least one second voxel. The method still further includes generating a radiation treatment plan based at least part on the dose value corresponding to the at least one second voxel.

    摘要： A method for magnetic resonance imaging (MRI) may include obtaining a plurality of first magnetic resonance (MR) data sets related to a region of interest (ROI) of a subject. The plurality of first MR data sets may be collected based on two or more different values of a scan parameter. The method may also include determining a plurality of second MR data sets based on the plurality of first MR data sets. Each of the plurality of second MR data sets may correspond to at least two of the plurality of first MR data sets. The method may also include generate, based on the plurality of second MR data sets, a plurality of T1 weighted images of the ROI each of which corresponds to a target time point.
