The vision of the application scenario MEDICO is to establish syntax and semantics based on image vocabularies to build an intelligent scalable robust search engine for the medical domain, with applications in Clinical Decision Support and Computer Aided Diagnosis Systems.
A principal contributions to the MEDICO project are methods allowing fast image-based similarity queries. As image similarity is not clearly defined, we develop adaptive similarity measures for various kinds and combinations of image descriptors. One example for similarity queries on medical images is the localization of the current body height of a given single query image using k-nearest neighbor regression as in the image below.
An even more challenging application is the transfer of similarity queries to actual 3-dimensional query regions. Our system enables a physician to outline a region of interest in an image volume as query resulting in a list of similar scans for patients comparable in manually annotated and automatically induced diagnosis. (See also an illustrating video on the Theseus Medico YouTube Channel.)
The latest news on THESEUS MEDICO are posted on our twitter channel.
Some of the basic technologies being developed by the research partners are functions for the automatic creation of metadata for audio, video, 2D and 3D picture files and their application-specific combination, as well as mechanisms for the semantic processing of multimedia documents and their associated services.
The research partners are working on scalable technology for shaping and structuring ontologies. In the course of this work, they will utilise innovative processes based on machine learning principles; these will help them to discover logical-deterministic and probabilistic relationships in text, audio, image and video data. This, in turn, will allow statistical Machine Learning methods to be developed that will make the extraction of knowledge from relational data possible; this data can then be used to create or extend existing ontologies.
One of our last projects within the CTC was the creation of supplementary tools for the Use Case MEDICO by processing computer tomography (CT) scans in order to apply the possibility of similarity search upon image data. The image below illustrates the concept of a possible workflow.
