近距离放射治疗处置规划系统
摘要：
一种近距离放射治疗处置规划系统包括处理器，所述处理器：接收对应于前列腺的至少部分的规划图像；生成近距离放射治疗处置计划，对于多个近距离放射治疗种子或导管中的每个，所述计划包括在规划图像中的对应的近距离放射治疗种子或导管位置，使得在规划图像中的多个近距离放射治疗种子或导管位置一起满足在前列腺中的期望的放射性剂量目标；接收对应于前列腺的至少部分的处置前图像；并且通过执行在规划图像和处置前图像之间的配准将规划图像中的每个近距离放射治疗种子或导管位置映射为在处置前图像中的对应的位置。
摘要（英）：

A brachytherapy treatment planning system includes a processor that: receives a planning image corresponding to at least a portion of a prostate; generates a brachytherapy treatment plan comprising, for each of a plurality of brachytherapy seeds or catheters, a corresponding brachytherapy seed or catheter position in the planning image such that the plurality of brachytherapy seed or catheter positions in the planning image together satisfy a desired radioactive dose objective in the prostate; receives a pre-treatment image corresponding to the at least a portion of a prostate; and maps each brachytherapy seed or catheter position in the planning image to a corresponding position in the pre-treatment image by performing a registration between the planning image and the pre-treatment image.
