Sparsity techniques in medical imaging
With the advent of the age for big data and complex structure, sparsity has been an important modeling tool in compressed sensing, machine learning, image processing, neuroscience and statistics. In the medical imaging field, sparsity methods have been successfully used in image reconstruction, image enhancement, image segmentation, anomaly detection, disease classification, and image database retrieval. Developing more powerful sparsity models for a large range of medical imaging and medical image analysis problems as well as efficient optimization and learning algorithm will keep being a main research topic in this field...

According to the International Diabetes Federation (IDF), 366 million people were diagnosed with diabetes in 2011. It is expected that the number will increase to 522 million in 2030. In addition, 183 million people (50%) with diabetes are not diagnosed [1]. Due to the prolific increase in diabetes, based on current estimates, a minimum of 3 million people will need to be evaluated every day by the year 2030 (35 tests per second).

Sparse Group Composition for Robust Left Ventricular Epicardium Segmentation
Left ventricular (LV) epicardium segmentation in cardiac magnetic resonance images (MRIs) is still a challenging task, where the a-priori knowledge like those that incorporate the heart shape model is usually used to derive reasonable segmentation results. In this paper, we propose a sparse group composition (SGC) approach to model multiple shapes simultaneously, which extends conventional sparsity-based single shape prior modeling to incorporate a-priori spatial constraint information among multiple shapes on-the-fly.

Automatic Brain Tumour Detection and Neovasculature Assessment with Multiseries MRI Analysis
Brain tumours belong to the group of tumours the most difficult to be treated as they often affect areas where the treatment of choice, namely the total tumour resection, is virtually impossible. Correct decisions concerning surgery, radiotherapy and chemotherapy planning strictly depend on the accuracy of tumour segmentation performed by a radiologist [1–3]. The task consists of outlining the suspected areas on each image, comparing and assessing the regions on multiple MR (Magnetic Resonance) series, marking the reference regions for calculations, etc. (Source: Computerized Medical Imaging and Graphics)

Volumetric relief map for intracranial cerebrospinal fluid distribution analysis
The central nervous system is surrounded by cerebrospinal fluid that is contained within the cerebral ventricles and subarachnoid space. Fluid is produced within the ventricles and circulates to the superior cortical subarachnoid space where it is resorbed into the circulatory system through arachnoid granulations [1]. The observation of cerebrospinal fluid plays a valuable role in the clinical diagnosis of brain disorders such as hydrocephalus and Alzheimer's disease [2,3]. One example is hydrocephalus, which is usually the result of obstructed fluid outflow in the ventricles or subarachnoid space that leads to an alterat...

Measuring Sparse Temporal-Variation for Accurate Registration of Dynamic Contrast-Enhanced Breast MR Images
Image registration is a vital process in the dynamic contrast-enhanced (DCE) magnetic resonance (MR) imaging based breast tumor diagnosis. DCE-MR imaging based examinations generally involves multi-times of imaging on the breast volume before and after the administration of a contrast agent, yielding the pre-contrast image and a series of post-contrast images. In DCE-MR images, tumor region can have various contrast enhancement patterns due to the agent, leading to significant temporal intensity changes. (Source: Computerized Medical Imaging and Graphics)

Landmark Constrained Registration of High-Genus Surfaces Applied to Vestibular System Morphometry
Surface-based morphometry has become one of the most ubiquitous shape analysis techniques in medical image analysis. For example, in human brain mapping, the morphometry of brain cortical surfaces has been extensively studied to detect shape changes during disease progression or healthy aging. The hippocampal surface morphometry has also been an active research field to study the Alzheimer's disease. (Source: Computerized Medical Imaging and Graphics)

Accelerometric Signals in Automatic Balance Assessment
The clinical balance assessment has been an object of study in the past years [1]. Various disorders and diseases (Parkinson's disease, multiple sclerosis, neurological and musculoskeletal diseases [2,3]) are accompanied by balance problems. Due to the aging of contemporary societies, the safety and well-being of the elderly emerges as one of the major concerns in health care; this general consideration easily covers balance assessment and therapy. The postural perturbations and balance disorders control is critical for the selection of the proper treatment and rehabilitation [4]. (Source: Computerized Medical Imaging and Graphics)

The quantitative assessment of the pre- and postoperative craniosynostosis using the methods of image analysis
Craniosynostosis is a common condition which affects infants. The disease is caused by the premature fusion of one or more cranial sutures which changes the growth pattern of the skull [1,2]. Skull shape deformations and the resulting increased intracranial brain pressure may in turn cause a noticeable disorder in the neuropsychological development of a child.

Tissue-Specific Sparse Deconvolution for Brain CT Perfusion
Cerebral computed tomography perfusion (CTP) imaging has been advocated to detect and characterize the ischemic penumbra, and assess blood-brain barrier permeability with acute stroke or chronic cerebrovascular disease. In cerebral studies, perfusion hymodynamic parameters such as cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT) can be computed from the time sequence of enhanced CT images to provide important guidance to clinicians. However, the associated excessive radiation exposure in the repeated scan during CTP examination is raising a great concern due to numerous recent reports from...

Skeleton Graph Matching vs. Maximum Weight Cliques Aorta Registration Techniques
Nowadays, vascular diseases belong to the most challenging health problems in developed countries. According to statistics acquired by the Centers for Disease Control and Prevention (CDC), abdominal aortic aneurysms (AAAs) have been the cause of around 10000 deaths only in the United States in 2009. A bit decreased, but still around 7000 deaths annually, have been indicated for the United Kingdom, by the British Heart Foundation (retrieved 2011). For the year 2012 the Statistical Federal Agency has counted 3500 deaths caused by AAA in Germany. (Source: Computerized Medical Imaging and Graphics)
