  • A hierarchical multi-task approach to gastrointestinal image analysis
    Galdran, Adrian; Carneiro, Gustavo; González Ballester, Miguel Ángel, 1973- (Springer, 2021)
    A large number of different lesions and pathologies can affect the human digestive system, resulting in life-threatening situations. Early detection plays a relevant role in the successful treatment and the increase of ...
  • Automatic labeling of vascular structures with topological constraints via HMM
    Wang, Xingce; Liu, Yue; Wu, Zhongke; Mou, Xiao; Zhou, Mingquan; González Ballester, Miguel Ángel, 1973-; Zhang, Chong (Springer, 2017)
    Identifcation of anatomical vessel branches is a prerequisite task for diagnosis, treatment and inter-subject comparison. We propose a novel graph labeling approach to anatomically label vascular structures of interest. ...
  • Balanced-mixup for highly imbalanced medical image classification
    Galdran, Adrian; Carneiro, Gustavo; González Ballester, Miguel Ángel, 1973- (Springer, 2021)
    Highly imbalanced datasets are ubiquitous in medical image classification problems. In such problems, it is often the case that rare classes associated to less prevalent diseases are severely under-represented in labeled ...
  • Cochlear finite element modelling, Mesh quality under SSM-Driven deformations
    Kjer, Hans Martin; Ceresa, Mario; Carranza, Noemí; Vera, Sergio; Pérez, Frederic; Barazzetti, Livia; Reyes, Mauricio; González Ballester, Miguel Ángel, 1973-; Paulsen, Rasmus (Technical University of Denmark, 2013)
    Combining a high resolution cochlear finite element model with a/npatient low resolution CT scan could provide benefits for the use and implantation/nof cochlear implants. In order to do so requires a cochlear statistical ...
  • Double encoder-decoder networks for gastrointestinal polyp segmentation
    Galdran, Adrian; Carneiro, Gustavo; González Ballester, Miguel Ángel, 1973- (Springer, 2021)
    Polyps represent an early sign of the development of Colorectal Cancer. The standard procedure for their detection consists of colonoscopic examination of the gastrointestinal tract. However, the wide range of polyp shapes ...
  • Early prediction of Alzheimer's disease with non-local patch-based longitudinal descriptors
    Sanromà, Gerard; Andrea, Víctor; Benkarim, Oualid M.; Manjón, José V.; Coupé, Pierrick; Camara, Oscar; Piella Fenoy, Gemma; González Ballester, Miguel Ángel, 1973- (Springer, 2017)
    Alzheimer’s disease (AD) is characterized by a progressive decline in the cognitive functions accompanied by an atrophic process which can already be observed in the early stages using magnetic resonance images (MRI). ...
  • Estimating 3D ventricular shape from 2D echocardiography: feasibility and effect of noise
    Bernardino Perez, Gabriel; Butakoff, Constantine; Nuñez-Garcia, Marta; Sarvari, Sebastian Imre; Rodriguez López, Mérida; Crispi Brillas, Fàtima; González Ballester, Miguel Ángel, 1973-; Craene, Mathieu de; Bijnens, Bart (Springer, 2017)
    Many cardiac diseases are associated with changes in ventricular shape. However, in daily practice, the heart is mostly assessed by 2D echocardiography only. While 3D techniques are available, they are rarely used. In this ...
  • Finite element model for patient-specific functional simulations of cochlear implants
    Ceresa, Mario; Kjer, Hans Martin; Vera, Sergio; Carranza, Noemí; Pérez, Frederic; Barazzetti, Livia; Mistrik, Pavel; Dhanasingh, Anandhan; Caversaccio, Marco; Stauber, Martin; Reyes, Mauricio; Paulsen, Rasmus; González Ballester, Miguel Ángel, 1973- (Technical University of Denmark, 2013)
    We present an innovative image analyisis pipeline to perform/npatient-speci c biomechanical and functional simulations of the inner human/near. A high-resolution, cadaveric, mCT volumetric image portraying/nthe detailed ...
  • Medical-based deep curriculum learning for improved fracture classification
    Jiménez Sánchez, Amelia; Mateus, Diana; Kirchhoff, Sonja; Kirchhoff, Chlodwig; Biberthaler, Peter; Navab, Nassir; González Ballester, Miguel Ángel, 1973-; Piella Fenoy, Gemma (Springer, 2019)
    Current deep-learning based methods do not easily integrate to clinical protocols, neither take full advantage of medical knowledge. In this work, we propose and compare several strategies relying on curriculum learning, ...
  • Test time transform prediction for open set histopathological image recognition
    Galdran, Adrian; Hewitt, Katherine J.; Ghaffari Laleh, Narmin; Kather, Jakob N.; Carneiro, Gustavo; González Ballester, Miguel Ángel, 1973- (Springer, 2022)
    Tissue typology annotation in Whole Slide histological images is a complex and tedious, yet necessary task for the development of computational pathology models. We propose to address this problem by applying Open Set ...
  • The Candidate multi-cut for cell segmentation
    Funke, Jan; Zhang, Chong; Pietzsch, Tobias; González Ballester, Miguel Ángel, 1973-; Saalfeld, Stephan (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Two successful approaches for the segmentation of biomedical images are (1) the selection of segment candidates from a merge-tree, and (2) the clustering of small superpixels by solving a Multi-Cut problem. In this paper, ...
  • The Role of indirect mechanotransduction phenomena in microtrauma development within intervertebral discs – a computational biophysical analysis
    Baumgartner, Laura; González Ballester, Miguel Ángel, 1973-; Noailly, Jérôme (International Research Council on Biomechanics of Injury (IRCOBI), 2018)
    The causes of intervertebral disc (IVD) ruptures continue to elude both biomechanists and clinicians. It is widely accepted that unique traumatic high‐load impacts are unlikely to lead to isolated IVD herniation. Therefore, ...
  • Volumetric anatomical parameterization and meshing for inter-patient liver coordinate system definition
    Vera, Sergio; González Ballester, Miguel Ángel, 1973-; Gil, Debora (Technical University of Denmark, 2013)
    A coordinate system parameterizing the interior of organs is/na powerful tool for a systematic localization of injured tissue. If the same/ncoordinate values are assigned to speci c anatomical sites, parameterizations/nensure ...
