The paper ‘Three-dimensional solid texture analysis in biomedical imaging: Review and opportunities’ by Adrien Depeursinge et al. is among the Top 25 Hottest Articles from the Medical Image Analysis journal for the first quarter of 2014.  

A b s t r a c t
Three-dimensional computerized characterization of biomedical solid textures is key to large-scale and high-throughput screening of imaging data. Such data increasingly become available in the clinical and research environments with an ever increasing spatial resolution. In this text we exhaustively analyze the state-of-the-art in 3-D biomedical texture analysis to identify the specific needs of the application domains and extract promising trends in image processing algorithms. The geometrical properties of biomedical textures are studied both in their natural space and on digitized lattices. It is found that most of the tissue types have strong multi-scale directional properties, that are well captured by imaging protocols with high resolutions and spherical spatial transfer functions. The information modeled by the various
image processing techniques is analyzed and visualized by displaying their 3-D texture primitives. We demonstrate that non-convolutional approaches are expected to provide best results when the size of structures are inferior to five voxels. For larger structures, it is shown that only multi-scale directional convolutional approaches that are non-separable allow for an unbiased modeling of 3-D biomedical textures. With the increase of high-resolution isotropic imaging protocols in clinical routine and research, these models are expected to best leverage the wealth of 3-D biomedical texture analysis in the future. Future research directions and opportunities are proposed to efficiently model personalized image-based phenotypes of normal biomedical tissue and its alterations. The integration of the clinical and genomic context is expected to better explain the intra class variation of healthy biomedical textures. Using texture synthesis, this provides the exciting opportunity to simulate and visualize texture atlases of normal ageing process and disease progression for enhanced treatment planning and clinical care management.

 

The medGIFT group has three presentations scheduled at the 36th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC 2014). The conference takes place from August 26-30 in Chicago, USA.

ParaDISE (Parallel Distributed Image Search Engine) is an image retrieval engine developed by the medGIFT research group as a replacement of the GIFT search engine in the context of the KHRESMOI project. The main concepts behind its design are scalability, flexibility, expandability and interoperability, allowing it to be used in standalone applications, integrated systems and for research purposes.

ParaDISE can be found at http://paradise.khresmoi.eu/

 

The research stay of Antonio Foncubierta at Martinos Center of Harvard Medical School finishes this week. 

He’ll return to medGIFT offices in Sierre for his Thesis Defense in September.

The presentations ‘Anatomical correlations for a hierarchical multi-atlas segmentation of the pancreas in CT images’ and ‘Anatomical correlations for a hierarchical multi-atlas segmentation of CT images’ by Oscar Jiménez and Henning Müller were presented at the IEEE International Symposium on Biomedical Imaging (ISBI) 2014. 

The presentations were part of the ISBI challenges ‘Pancreas segmentation in Abdominal CT’ and VISCERAL ISBI challenge. The symposium took place from 29 April to 2 May in Beijing, China. 

A draft version of the submitted paper can be accessed through our publications website.

Digital health, or e-health, is one of the major issues of the 21st century. The second E-health Day on 6 June 2014 will be a chance to discover both Swiss and international expertise in this field. This expertise is found in applied research as well as in young companies and well-established SMEs.

The event, drawing above all on real-life case studies, will give all those attending a chance to gain a relatively exhaustive overview of the issues and the main players in the field, as well as the challenges that await them.
This day is also intended to be an exchange and networking opportunity.

We look forward to welcoming you!
