Heart: Imaging and Modelling Challenges

http://cilab2.upf.edu/stacom_cesc11/

September 22, 2011, Toronto, Canada


Submissions:
------------

Authors are invited to submit articles with a limit of 8 pages. The format
should follow the LNCS style following the MICCAI main conference
guidelines. A double-blind review process will be applied judging
submissions for originality, relevancy and significance. The paper
submission system is now open. Authors need to pre-register until 15th of
June with the title of the article, author list and a temporary PDF / DOC
file. For registration please visit:

The final versions of the articles are due 30th of June.

Overview:
---------

This workshop will follow on from last year’s successful STACOM’10 workshop,
which attracted over 50 participants and was published in the Springer LNCS
series. This year the workshop will be more focused on validation and
benchmarking of cardiac image analysis and simulation tools in order to
advance towards their application in clinical environments. Three challenges
utilizing data from human, phantom and animal studies will be organized: a
segmentation challenge involving patient data from the Cardiac Atlas Project
(CAP) led by the University of Auckland; a motion/deformation challenge
based on temporal 3D-US and MR images acquired from humans and from a
dynamic phantom at King’s College London; and a simulation challenge
involving electrophysiological (EP) data acquired in experimental animal
studies at Sunnybrook Research Institute, Toronto. These challenges will
provide a forum for the discussion of the latest developments in the areas
of heart mapping, including atlas construction, statistical modeling of
cardiac function across patient groups, cardiac computational physiology,
model personalization, ontological schemata for data and results, atlas
based functional analysis, and integrated functional/structural analyses, as
well as the clinical applicability of these methods. The workshop will be of
interest to computer scientists working in imaging and computational
modeling, but also to experts in cardiology, radiology, biology and
physiology. Through this workshop we would also particularly like to engage
a new generation of early career researchers in working at these interfaces.


Topics:
-------

   1. Efficient and robust statistical representations of cardiac morphology
and morphodynamics
   2. Quantitative analysis of cardiac images through segmentation and
motion/deformation estimation techniques
   3. Atlas construction methods.
   4. Sharing and reuse of computational cardiac anatomical, mechanical and
electrophysiological models
   5. Strategies for the personalization of cardiac computational models
   6. Parameter sensitivity quantification and identification of relevant
parameters in complex computational models
   7. Integration of multimodal data in a common reference space
   8. Clinical translation of imaging and modelling techniques
   9. Statistical analysis of regional heart shape and wall motion
characteristics across population groups.
  10. Atlas-based physiological analysis of subject-specific
characteristics.


Challenges:
-----------

- Segmentation Challenge: A segmentation challenge will also be included in
this workshop, utilizing data from the Cardiac Atlas Project (
www.cardiacatlas.org). MRI cine data from up to 300 patients with myocardial
infarction will be made available to participants in order to compare
automatic segmentation results with a manual ground truth 4D segmentation
provided by expert analysts. Participants will submit segmentation results
in a standard format, and these will be used to derive consensus
segmentations that will be made available in the Cardiac Atlas database for
future studies. STAPLE-based techniques will be explored to compare
different segmentation results. Points of difference from previous
segmentation challenges include the upload of results for development of
consensus ground truth for future studies, and time varying analysis
including ejection and filling rates. Also, a subset of data with
corresponding segmentations will be available from the beginning as a
training set.

- Motion Tracking Challenge: A motion tracking challenge will also be
included in this workshop, using both phantom-based and human kinematic data
obtained at University of Ulm and at King’s College London, respectively. A
cardiac phantom will be scanned several times to generate a fully controlled
set of temporal 3D ultrasound and cine/tagged MR images. In addition, 4D
echo and 4D cine/tagged MRI will also be available for a set of human
volunteers. Subsequently, both types of data will be processed to generate
ground-truth to compare with the different motion estimation techniques. The
comparisons will also be made on other indexes, like the resulting regional
strain.

- EP Simulation Challenge: An EP simulation challenge will be included in
this workshop. The goal of this challenge is to compare strategies for the
customization of realistic cardiac computational models using in-vivo
experimental data. Two complete datasets obtained in a porcine model: one
healthy heart and one heart with chronic infarct (obtained at Sunnybrook
Research Institute, Toronto) will be provided in advance, such that all
submissions can use it. These datasets will contain 3D cardiac geometry,
scar and fiber orientations from high-resolution DT-MRI, as well as
endocardial and epicardial CARTO electro-anatomical maps. The EP maps were
acquired in-vivo, in sinus rhythm. Participants will submit results of their
customized models (for instance, they can include simulation of Purkinje
activation, analysis of EP signals, model parameterization, etc), in order
to allow discussions on different model customization and parametrization
strategies that could be of interest in future clinical applications.
