SUMMARY:BioMedIA Talk: Enzo Ferrante
DESCRIPTION:Title: Graph-based deformable registration: slice-to-volume mapping and context specific methods \nAbstract: Image registration methods\, which aim at aligning two or more images into one coordinate system\, are among the oldest and most widely used algorithms in computer vision. A particular type of registration algorithm\, known as graph-based deformable registration\, has become popular during the last decade given its robustness\, scalability\, efficiency and theoretical simplicity. In this thesis\, we extend this flexible framework to new scenarios\, and propose novel methodological contributions. \nWe start by formulating\, within the graph-based deformable registration framework\, the challenging slice-to-volume registration problem. We introduce a scalable\, modular and flexible formulation accommodating low-rank and high order terms\, which simultaneously selects the plane and estimates the in-plane deformation through a single shot optimization approach. The other two contributions included in this thesis are related to how semantic information can be encompassed within the registration process. Currently\, most of the methods rely on a single metric function explaining the similarity between the source and target images. We argue that incorporating semantic information to guide the registration process will further improve the accuracy of the results\, particularly in the presence of semantic labels making the registration a domain specific problem.

SUMMARY:BioMedIA Talk: Ioannis Katramados (COSMONiO)
DESCRIPTION:Title: The challenges of developing an active deep-learning platform \nAbstract:\nDeep learning is usually linked to Big Data. However\, there are several scientific\, engineering and medical imaging problems with limited data available (e.g. rare medical conditions). Can Deep Learning prove a useful tool in such cases? COSMONiO is designing NOUS\, an active deep learning platform that aims to make high-accuracy predictions using significantly smaller training datasets. NOUS aims to allow experts from any field to train neural networks without any prior experience. We will discuss the main challenges and how we address them.

SUMMARY:BioMedIA Talk: Leo Grady (HeartFlow)
DESCRIPTION:Personalized Blood Flow Simulation from an Image-Derived Model: Changing the Paradigm for Cardiovascular Diagnostics \nAbstract: Coronary heart disease is the leading cause of mortality worldwide\, accounting for 1/3 of all global deaths.  Treatment of stable coronary heart disease is typically performed by medication/lifestyle for a lower disease burden or PCI (stenting) for a greater disease  burden.  The choice between these treatments is best determined by an invasive diagnostic test that measures blood flow through a diseased area.  Unfortunately\, this invasive diagnostic test is expensive\, dangerous and usually finds a lower disease burden.  We are working to change the diagnostics paradigm with blood flow simulation in a personalized heart model that is derived from cardiac CT angiography images.  This simulation-based diagnostic is the first clinically available diagnostic that utilizes personalized simulation and is much safer and more comfortable for the patient as well as less expensive.  Our diagnostic depends on a hyperaccurate image segmentation of the coronary arteries\, physiological modeling and accurate computational fluid dynamics.  In this talk I will discuss the algorithms that drive this technology\, the machine learning that we’re doing with our database of segmented images and personalized hemodynamics\, and the successful clinical trials that have proven the diagnostic accuracy and benefit to patients. \n  \nBio: Leo Grady is the Vice President of Research and Development at HeartFlow since 2012.  Prior to joining HeartFlow\, he worked at Siemens Corporate Research for nine years as a Principal Research Scientist following his PhD at Boston University.  His work has focused on a range of computer vision and medical imaging applications in image segmentation and machine learning.  He has written two books on computer vision and data analysis using graph theory\, is an editor of several journals in computer vision and was recently inducted as a Fellow of the American Institute of Medical and Biomedical Engineers.

SUMMARY:BioMedIA Talk: Archontis Giannakidis (Royal Brompton)
DESCRIPTION:Improving clinical application of cardiac diffusion tensor MRI\nAbstract  Magnetic resonance diffusion tensor imaging (MRDTI)\, also known as DTI\, has emerged as a powerful non-invasive tool for mapping the orientation-dependent microanatomical organization of fibrous organs such as brain white matter and myocardium. To do so\, it elegantly relates the self-diffusion of water molecules that undergo Brownian motion to proton spin relaxation MR signals. In this talk it will be shown how DTI can shed some light on the left-ventricular micro-structural remodeling following hypertensive disease. A framework for the voxelwise registration-based characterization of cardiac disease will be considered. Population and longitudinal studies may benefit from such a scheme. Results from a comparison study will be presented juxtaposing the performance of three tensor distance functions. The selection of a tensor distance function resides in the foundation of the tensor-variate framework\, critically affecting many operations in the six-dimensional space of diffusion tensors. This seminar will end by discussing how sparsifying transforms can be used in conjunction with compressive sensing reconstruction to shorten acquisition times.

SUMMARY:BioMedIA Talk: Purang Abolmaesumi (University of British Columbia)
DESCRIPTION:Quantitative Ultrasound Imaging for Diagnosis and Intervention: A Machine Learning Approach \nAbstract: In recent years\, quantitative ultrasound has emerged as a promising technology to improve diagnosis\, increase the precision of interventions\, and automate the acquisition of data specially in point-of- care settings. Advancements in machine learning and computation power have contributed significantly to these developments in quantitative imaging.\nIn this talk\, I present three main developments in our laboratory based on quantitative ultrasound: \n\nFor prostate cancer diagnosis\, I present our work based on the analysis of temporal ultrasound data. I compare the cancer detection and grading accuracy based on temporal ultrasound with multi-parametric MRI in a fusion biopsy study on more than 150 patients. Our results demonstrate that a combination of temporal ultrasound and MRI can accurately predict prostate histopathology determined by biopsy samples.\nFor spine anesthesia and analgesia\, I present the result of our work on combining anatomical models with ultrasound data to facilitate image interpretation in the spine region. Furthermore\, I demonstrate that using advanced machine learning techniques\, automation of image interpretation of the spine is feasible.\nFor echocardiography\, we have access to more than 200\,000 patient records based on clinical data obtained over the last 10 years in Vancouver. I present the initial results of our research on 7\,000 patients both in automatic analysis of data to improve measurement accuracy\, and to assign an image quality factor to the data to facilitate image acquisition.\n\nBio: Purang Abolmaesumi is the Canada Research Chair in Biomedical Engineering\, a Killam Research Prize recipient\, and Professor in the Department of Electrical and Computer Engineering at the University of British Columbia\, Vancouver\, BC\, Canada. He is internationally recognized and has received numerous awards for his pioneering developments in ultrasound image processing\, image registration and image-guided interventions. He is the General Chair of the International Conference on Information Processing in Computer Assisted Intervention\, 2014-2017\, and has served on the program committees of the Medical Image Computing and Computing and Computer Assisted Intervention (MICCAI) and International Society for Optics and Photonics (SPIE) Medical Imaging. Dr. Abolmaesumi is an Associate Editor of the IEEE Transactions on Medical Imaging\, and has served as an Associate Editor of the IEEE Transactions on Biomedical Engineering. His techniques for ultrasound segmentation have been adopted to develop a prostate brachytherapy planning interface that is now the standard-of- care in British Columbia and has been used to treat more than 2\,000 patients.

SUMMARY:BioMedIA Talk: Enrico Grisan (University of Padova)
DESCRIPTION:Segmenting 2D+T ultrasound imaging data in fetus: improving the estimation of biomarkers of risky adaptations \nAbstract: Approximately 10% of the pregnancies are complicated by growth restriction and 7% of pregnancies are complicated by gestational diabetes mellitus (GDM). In addition\, the increasing rate of obesity will likely rise the proportion of pregnancies complicated by both Type 2 diabetes mellitus and GDM. Exposure to either dysglycaemia and poor nutrition may have a long-term impact on the developing child’s physiology\, potentially programming for an increased risk of cardiovascular disease in later life… The full abstract is attached. \nBio: Enrico Grisan graduated in Electrical Engineering at the University of Padova in 2001\, and he was then research consultant for the University of Padova and Nidek Technologies. In 2005 he earned the PhD in Bioengineering jointly from University of Padova and City University London. After being intern at Siemens Corporate Research in 2005\, and then post-doc fellow in Padova from 2005 to 2008\, he has been appointed (tenured) Assistant Professor in Bioengineering since 2008 His main research activities involve the automatic analysis of medical images and the discovery of clinical biomarkers from them. He has been working on retinal images for the quantification or retinopathy-related changes\, on confocal endomicroscopy images for virtual histology\, on multispectral MRI for quantifying cortical lesion burden\, on perfusion patterns in contrast-enhanced ultrasound\, and finally on prenatal ultrasound.

SUMMARY:BACON: Workshop on Brain Analysis using Connectivity Networks
DESCRIPTION:Understanding brain connectivity in a network-theoretic context has shown much promise in recent years. This type of analysis identifies brain organisational principles\, bringing a new perspective to neuroscience. At the same time\, large public databases of connectomic data are now available. However\, connectome analysis is still an emerging field and there is a crucial need for robust computational methods to fully unravel its potential. This workshop provides a platform to discuss the development of new analytic techniques; methods for evaluating and validating commonly used approaches; as well as the effects of variations in pre-processing steps. \nThis year we are co-organising the workshop on Brain Analysis using Connectivity Networks at MICCAI’16 in Athens in the morning of Monday 17/10/2016.  Please consider to submit your work until 17/06/2016! \n

SUMMARY:BioMedIA Talk: Olaf Ronneberger (Google DeepMind / Albert-Ludwigs-Universität Freiburg)
DESCRIPTION:U-net: Convolutional Networks for Biomedical Image Segmentation \nAbstract: In this talk I will present our u-net for biomedical image segmentation. The architecture consists of an analysis path and a synthesis path with additional shortcut-connections. The network is trained end-to-end from scratch with a very low number of annotated images per application. The surprisingly simple strategy to train a network with such a low number of samples is a data augmentation with elastic deformations. Furthermore the u-net can segment arbitrarily large images with a seamless tiling strategy. For 3D images we have developed a training strategy to learn a full 3D segmentation from a few annotated slices per volume. This can be used in a semi-automated setup to create a dense segmentation from the sparse annotations on the same volume\, or in a fully-automated setup\, where sparse annotations speed up the training data generation significantly. \nReferences:\nO.

SUMMARY:BioMedIA Talk: Matthan Caan (Academic Medical Centre & Spinoza Centre for Neuroimaging\, Amsterdam)
DESCRIPTION:Quantifying MRI: from reconstruction to application in neuroimaging \nAbstract: To understand the origin and development of neurological disorders\, Magnetic Resonance Imaging (MRI) has proven to provide valuable quantitative measures. In this overview presentation\, I will touch upon several topics. Volumetric measures obtained via segmentation find their application in prenatal famine exposure\, HIV and ischemic stroke. We developed a scattering transform that has no learnable parameters for computing convolutional neural networks in small patient studies. Diffusion MRI is a sensitive method for detecting microstructural changes. We assessed the reproducibility of different models in a multi-site context using a complex diffusion phantom. T1\, T2* and Quantitative Susceptibility Mapping (QSM) allow for mapping myelin and iron content at high resolution at 7T. We present a single MRI sequence for obtaining these measures in a time efficient manner. Further acceleration may be achieved by compressed sensing and potentially deep learning.

SUMMARY:BioMedIA Talk: Raphael Sznitman (University of Bern\, Switzerland)
DESCRIPTION:Finding the needle in the haystack: detection\, tracking and registration in biomedical imaging\n  \nAbstract\n\n\n\nFrom centimeter-sized observations visible in endoscopy to nanometer large intra-cellular structures discernible with Electron Microscopes\, searching and locating objects of interest in images is a central problem in medical image computing. If anything\, the need for efficient object detection techniques has never been higher due to the advent of cheaper and ever more sophisticated imaging devices\, able of amassing unprecedented quantities of data. And while established search paradigms are showing their limits\, faster methods capable of dealing with larger quantities of data are now indispensable. \n\n\n\nIn this talk\, I will present a computational framework for object detection with efficiency at its core. This framework\, a Bayesian formulation of the traditional “twenty questions” game\, considers a sequential strategy for evaluating different parts of the image data in order to locate the object effectively. In this context\, we will see how dynamic programming and information theory can be used to characterize a provably-optimal search strategy that is both simple to compute and greedy in nature. Using these results\, I will then show how this framework can be used to solve traditional object detection and tracking problems\, as well as non-rigid registration of multimodal multi-scale image data\, allowing for more accurate solutions and large problems to be tackled. \n\n\n\nShort Bio:\nRaphael Sznitman received his B.Sc. in cognitive science from the University of British Columbia (Canada) in 2007. Following this\, he studied Computer Science at Johns Hopkins University where he received his M.Sc and PhD in 2011. From 2011 to 2014\, he was a postdoctoral fellow at the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland. Now an Assistant Professor at the ARTORG Center for Biomedical Engineering Research of the University of Bern (Switzerland)\, his research interests lie in the fields of computer vision and machine learning with applications to biomedical imaging\, surgery and histology.
