An Ontology Visualization Tool for Indexing DICOM Structured Reporting (SR) Documents

In the medical fields, images and reports of patients are increasingly being held in a digital form. To overcome the problem of heterogeneity due to the use of different devices between the various specialties, DICOM SR standard (Digital Imaging and Communications in Medicine for Structured Reporting) has emerged. For the medical imaging community taking advantage of this standard to improve medical image retrieval systems become a challenging research issue. In this context, the aim of this paper is a preliminary contribution to an efficient indexing process of DICOM SR documents. We propose to guide this process with an ontology. We describe our motivations for building this ontology by reusing existing ontologies. Then, a specific ontology visualization tool is suggested for imagers to assist their indexing.
