Deformable object segmentation in ultra-sound images

2013

Breast cancer is the second most common type of cancer being the leading cause of cancer death among females both in western and in economically developing countries. Medical imaging is key for early detection, diagnosis and treatment follow-up. Despite Digital Mammography (DM) remains the reference imaging modality, Ultra-Sound (US) imaging has proven to be a successful adjunct image modality for breast cancer screening, specially as a consequence of the discriminative capabilities that US offers for differentiating between solid lesions that are benign or malignant. Despite US usability,US suffers inconveniences due to its natural noise that compromises the diagnosis capabilities of radio…

Segmentation d'images robuste appliqué à l'imagerie par résonance magnétique et l'échographie de la prostate

2012

Prostate segmentation in trans rectal ultrasound (TRUS) and magnetic resonanceimages (MRI) facilitates volume estimation, multi-modal image registration, surgicalplaning and image guided prostate biopsies. The objective of this thesis is to developshape and region prior deformable models for accurate, robust and computationallyefficient prostate segmentation in TRUS and MRI images. Primary contributionof this thesis is in adopting a probabilistic learning approach to achieve soft classificationof the prostate for automatic initialization and evolution of a shape andregion prior deformable models for prostate segmentation in TRUS images. Twodeformable models are developed for the purpose. An…

Dirección de tesis doctorales como reflejo de la Biblioteconomía y Documentación académica española: actores y temas

2020

Doctoral dissertations enable the transfer of research skills and capacities to future generations and the consolidation of lines of research in a given area of knowledge. The field of Library and Information Science in public universities in Spain is characterized by the supervision of doctoral theses by academics in the area. We identified active professors during the 2019–2020 academic year, their date of appointment as civil servants within the public university system, the dissertations that they supervised, and their participation in papers published in scientific journals. The analysis included 644 theses. About a quarter (23%) of university faculty have never supervised a doctoral t…
