Locating The Eyes In Ct Brain-Scan Data

In this document, a technique for locating the eyes in Computed Tomography brainscan data, is described. The objective is to automatically localise the eyes for protectionduring radiotherapy planning. The image feature that is exploited is the circularity of theeyes. After data preprocessing to remove parts of the CT machinery, signature analysis isperformed to locate areas of interest. By applying Canny's edge detector to these areas,data is further reduced to the significant edge...
