Ablative Margin
Description
The tumor infiltrates the neighboring organs, which leads to the tumor boundary unclear.
The ablation scope is larger than practical tumor boundary’s. The enlargement scope is
called ablative margin.
The ablative margin is about setting a safe boundary on the lesion which is already
marked. It also implies another boundary mark outside the lesion mark on image. .
The ablative margin reminds of the narrowest boundary for surgical ablation. It takes
significant effect on ablating the tumor.
Operation
