It will be presented in the 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC’13) to be held in Osaka International Convention Center, in Osaka, Japan on July 3-7, 2013.


'Medical 3D data retrieval' keynote talk at Eurographics2013

Prof. Henning Müller has been invited as a speaker at the Eurographics Workshop on 3D Object Retrieval. This event will take place in Girona (Spain) May 11-2013. 

The Keynote talk is called “Medical 3D data retrieval”:

Medical tomographic data is produced in enormous quantities and currently very little of the knowledge stored in past cases has been exploited as data is only used in the context of single patients. In difference to object retrieval, tomographic data represents solid texture and the texture variation inside objects is usually more important than shapes of structures. The presentation will describe methods for retrieval of solid medical 3D texture in several applications and ways to better exploit existing medical data. 

The VISCERAL challenge in medical images segmentation and retrieval will be presented that has the goal to bring medical 3Ddata analysis towards big data. Several terabytes of data will be made available to the scientific community to first identify important body parts and then retrieve similar cases for challenges that will be run inside the cloud. 


'Medical Content-Based Retrieval for Clinical Decision Support' available online

The book ‘Medical Content-Based Retrieval for Clinical Decision Support’ is now available online. Prof. Henning Müller contributes as editor. 

This book constitutes the refereed proceedings of the Third MICCAI Workshop on Medical Content-Based Retrieval for Clinical Decision Support, MCBR-CBS 2012, held in Nice, France, in October 2012.
The 10 revised full papers presented together with 2 invited talks were carefully reviewed and selected from 15 submissions. The papers are divided on several topics on image analysis of visual or multimodal medical data (X-ray, MRI, CT, echo videos, time series data), machine learning of disease correlations in visual or multimodal data, algorithms for indexing and retrieval of data from visual or multimodal medical databases, disease model-building and clinical decision support systems based on visual or multimodal analysis, algorithms for medical image retrieval or classification, systems of retrieval or classification using the ImageCLEF collection.

PROMISE 'Information Retrieval Meets Information Visualization' book available online

‘Information Retrieval Meets Information Visualization’ book is now available online. It constitutes the outcome of the PROMISE Winter School 2012 and contains 11 invited lectures from the research domains information retrieval and information visualization. A large variety of subjects are covered, including hot topics such as crowdsourcing and social media.

The research domains information retrieval and information visualization have always been independent from each other. However, they have the potential to be mutually beneficial. With this in mind, a writer school was organized in Zinal, Switzerland, in January 2012, within the context of the EU-funded research project PROMISE (Participative Research Laboratory for Multimedia and Multilingual Information Systems Evaluation).  PROMISE aims at advancing the experimental evaluation of complex multimedia and multilingual information systems in order to support individuals, commercial entities, and communities who design, develop, employ, and improve such complex systems. The overall goal of PROMISE is to deliver a unified environment collecting data, knowledge, tools, and methodologies, and to help the user community involved in experimental evaluation.

Information Access to Medical Image Data presentation at DBTA workshop

Prof. Henning Müller gave the presentation Information Access to Medical Image Data: from Big Data to Semantics – Academic and Commercial Challenges at the DBTA Workshop on Academic-Industrial Forms of Collaboration at the University of Lausanne.

The presentation introduced two EU funded projects called Khresmoi and Visceral and highlighted the collaborations of HES-SO with several companies in these projects and also with other Universities and institutions in Switzerland.  


Focus Theme on Methods of Information in Medicine journal about Health Information Search

Prof. H. Müller was guest editor together with A. Hanbury and N. Al Shorbaji in the Focus Theme  of  Methods of Information in Medicine journal.  The focus theme in this issue is Health Information Search Combining Text, Visual Information, and Knowledge Bases. 

This is a journal that has stressed, for more than 50 year, the methodology and scientific fundamentals of organizing, representing and analysing data, information and knowledge in biomedicine and health care.
