Abstract

Abstract. The proposed use case focuses on interoperating between a rule base and a brain cortex anatomy ontology, in order to assist the labeling of the brain cortex structures- sulci and gyri- involved in MRI images. The use case documents the ontology and the rules so as to clarify the added value and needs of rules, and the language expressiveness required. The expected result is to get candidate languages extending OWL DL with rules that allow representing all the knowledge required (ontology and rules), joint with the properties of reasoning that are guaranteed. 1. Presentation of the application Our group is interested in image processing in the context of neuroimaging, applied both to medical practice, i.e. decision support in neurology and neurosurgery, and to research about neurological pathology such as epilepsy, dementia, etc. The considered application aims at developing new methods for assisting the labeling of the brain cortex structures- sulci and gyri- in MRI images. Indeed, nowadays the brain cortex can be automatically segmented but the problem remains to identify its various parts. Numerical tools previously developed at IDM provide a list of items corresponding to the gyrus parts and sulcus segments
