In many diseases, the interface between diseased and healthy tissue may contain a great deal of information. One example is the brain tumor oligodendroglioma, where characteristics of the tumor margin are significantly associated with 1p/19q co-deletion, which is a marker for good response to chemo- and radiation-therapy. In this abstract we report the design of a phantom to simulate invasive and non-invasive tissue border properties, and use a novel edge analysis technique to quantify these features.
