MICCAI Workshop on Statistical Atlases and Computational Models of the Heart: Imaging and Modelling Challenges Information 2012

------------------------ CALL FOR PAPERS ------------------------ MICCAI Workshop on Statistical Atlases and Computational Models of the Heart: Imaging and Modelling Challenges http://www.physense.org/stacom2012/ October 5, 2012, Nice, France Overview: --------- This workshop will follow on from the successful STACOM’10 and STACOM'11 workshops, which attracted over 50 participants each and were published in the Springer LNCS series (STACOM-CESC-10, LNCS 6364; STACOM'11, LNCS 7085). In addition, in the last two editions, collaborative research work between the participants led to some journal submissions (eg. see Camara et al., PBMB'11). This year the workshop will be focused again on both cardiac image analysis and simulation tools in order to advance towards their application in clinical environments. Challenges using data from human, phantom and animal studies will be organized on segmentation, landmarking, motion tracking and simulations. Challenges utilizing data from human, phantom and animal studies will be organized: a segmentation challenge on atria and ventricular structures from MRI involving patient and animal data from King's College London, the University of Utah and the KUL Leuven; a motion/deformation challenge based on synthetic temporal 3D-US coordinated by Philips Research Medysis; and a landmarking challenge on cardiac relevant anatomical features using the Cardiac Atlas Project (CAP) database, led by the University of Auckland; a Computational Fluid Dynamics (CFD) challenge organized by Siemens Corporation, Corporate Research and Technology and King's College London to evalute the performance of fluid simulations on patient-specific geometries. This forum 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: Delayed-enhancement magnetic resonance imaging is a powerful tool for detecting myocardial fibrosis and scarring in both the ventricles and atria. Recently there has been much interest in the quantification of DE-MRI for a variety of applications, in particular for atrial fibrillation, where scarring is recognized after a segmentation of atrial geometry. This challenge will make available 60 DE-MRI clinical data sets (from KCL and Utah) to challengers for segmentation of atrial geometry. 30 data sets will be from patients with atrial fibrillation that have been treated with radiofrequency ablation and imaged at least 3-months post-ablation. 30 data sets will be from patients that have been imaged post-myocardial infarction for assessment of ICD/pacemaker implants. In addition, DE-MRI on experimental models of chronic infarct (pigs) acquired in Leuven will be available (10 controls and 10 infarcted cases) together with manual delineations of endocardial/epicardial LV surfaces and scar. - Motion Tracking Challenge: STACOM will propose this year a new cardiac Motion Analysis Challenge (cMAC) centered on 3D ultrasound. The challenge will be coordinated by Philips Research Medisys (Paris) and organized in collaboration with Inria Asclepios (Nice), KUL Imaging Cardiovascular Dynamics (Leuven) and the CHU of Caen. Synthetic data with known ground truth will be provided to the challengers for simulated healthy and patient data (ischemic and LBBB). Strain accuracy will be quantified to study the localizability of electro-mechanical defects in myocardial deformation. Multimodal acquisitions on a physical phantom with heterogeneous mechanical properties will also be provided for comparing the different tracking algorithms. - Landmarking Challenge: Anatomical landmark annotation of the heart plays a significant role in cardiac MR analysis. It enables more robust and accurate functional and structural analysis of the heart. Yet, this pre-requisite step for an automated cardiac MRI segmentation method is usually determined by tedious and subjective manual positioning. In this challenge, the Cardiac Atlas Project will provide 100 test and 100 training sets, containing short-axis and long-axis views of cardiac cine MRIs. The training set will be accompanied by mitral valve points in long-axis views, and right ventricular insert points as well as left ventricle center points in short-axis views; all of them were determined manually by expert observers. The challenge will ask participant to detect mitral valve, RV inserts and LV centers from the test set. Only one condition must be met: the landmark detection should be fully automatic. Participants will be expected to present their methods and results at the workshop. A summary paper will be submitted to an appropriate journal, with authors from all participants. - CFD Simulation: a Computational Fluid Dynamics challenge is being organized for this workshop by Siemens Corporation, Corporate Research and Technology and King's College London. The goal of this challenge is to evaluate the performance of fluid dynamics simulations on patient-specific geometries. Ground-truth will be available in the form of PC-MRI.
