    • Example methods and systems for determining a treatment plan for a radiotherapy treatment system to deliver radiotherapy treatment to a patient are disclosed. In one embodiment, the method may comprise performing a particle transport simulation to initiate a first set of particle histories and a second set of particle histories from a radiation source of the radiotherapy treatment system to a treatment volume with multiple voxels representing an anatomy of the patient. The method may also comprise determining first cumulative costs associated with respective particle histories in the first set and second cumulative costs associated with respective particle histories in the second set. The method may further comprise selecting the first set or second set based on the first cumulative costs and second cumulative costs and determining the treatment plan based on the selected first set or second set.

    • A method for medical image segmentation includes accessing and updating a knowledge-base. A medical image is received and a sparse landmark signature is computed based on the medical image. Either a representative or a cohort average reference image set is selected. A portion of either representative reference image set or the cohort average reference image set is deformed to generate mappings to the medical image set. A segmentation for each structure of interest of the medical image set is determined. The knowledge-base is searched for representative matches to form a plurality of sub-volume base sets comprising a plurality of reference image set sub-volumes. A portion of the plurality of reference image set sub-volumes is deformed to generate mappings from the plurality of sub-volume base sets to corresponding structures of interest of the medical image set. A weighted-average segmentation for the structures of interest in the medical image set is calculated.
    • 用于医学图像分割的方法包括访问和更新知识库。 接收医学图像,并且基于医学图像计算稀疏地标签名。 选择代表性或队列平均参考图像集合。 代表参考图像集或队列平均参考图像集合的一部分变形以产生对医学图像集合的映射。 确定医学图像集合的感兴趣的每个结构的分割。 搜索知识库以进行代表性匹配以形成包括多个参考图像集子卷的多个子卷基本集合。 多个参考图像集子体积的一部分被变形以产生从多个子体积基本集合到医学图像集的感兴趣的相应结构的映射。 计算医学图像集中感兴趣结构的加权平均分割。
