Brain Tumor Segmentation and Display Using Dual-Echo MR Images

以雙重迴訊磁振造影展示腦瘤分割界限

摘要


雙重迴訊磁振造影提供了正常腦組織及腦瘤間優良的對比,這正是一般腦瘤病人在接受治療之前所必須的。以這些影像為基礎所作之腦瘤分割界限對於治療計劃之設定及治療後之追蹤檢查是非常有用的。我們以向量分解及或然率的方法在雙重迴訊磁振造影中將一個腦瘤作分割界限的工作報告出來。此外,三度空間影像之展示更可將腦瘤及皮膚清楚地表現出來。

Dual-echo MR brain images provide good contrast between tumors and normal tissues, and they are routine acquired for brain-tumor patients. Segmentation of brain tumors based on these images is useful for treatment planning and follow-up. We report the segmentation of a brain tumor on dual-echo MR images using a combined vector decomposition and probability method. Three- dimensional displays of tumor and skin surface are presented.
