Aims and objectives throughout the project
LaTIM is carrying out a multidisciplinary research programme involving
physicians and scientists within the framework of a close cooperation
between the School of Medicine, the University Hospital of Brest, and Telecom
Bretagne. The research concerns two themes, dynamic forms in medical
imaging on the one hand, and indexing and similarities in medical imaging on
the other. Both themes are integrated in a single methodological approach to
information -and knowledge- based medical image processing and analysis
for diagnostics and therapy.
The first research topic relates to the concept of dynamic forms in medical
imaging for the quantification of the structures and the functions. We seek
here to model the biomedical forms geometrically, with better apprehending
the relations between these forms and the dynamic functional dimension of
the anatomical structures which they represent and with better taking into
account the physiological movements which could degrade the interpretation
of the images. The final objective can be a quantification used at ends
diagnostic or therapeutic, the comparison with a model of reference (atlas),
the study of the evolution during the growth, the temporal variations during
the movement, as well for rigid anatomical structures elastic. The medical
applications are varied, since the study morpho-functional calculus of the
osteo-articular complexes, navigated orthopaedic surgery, the dating of the
venous thrombus by echography, until the quantification of the tumours in
PET imaging and the studies of therapeutic following or the planning aid in
radiotherapy.
The second topic of the laboratory is interested in the methods of indexing,
traceability and control of the integrity of multi-media medical information.
The central subject of this topic relates to the generation and the handling of
traces in the images, these traces being the elements characteristic of these
images which are intimately linked with them in terms of contents,
description, interpretation and history. These traces are used on a side for the
indexing and research by the contents in image databases, according to
criteria as well numerical as symbolic, and on another side for the control of
integrity of the images in order to guarantee the reliability of information
which they carry. The methodology used is at the cross road of image
engineering, knowledge engineering, cryptography and steganography and
endeavours to integrate these approaches into the profit of targeted
developments and applications, like exploration in digestive endoscopy, the
sharing of expertise in ophthalmology and the secured specialized electronic
patient record.
