1. 21. Manifold learning and representations for image analysis and visualization

   Författare :Anders Brun; Hans Knutsson; Magnus Herberthson; Carl-Fredrik Westin; Reiner Lenz; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; manifold learning; image analysis; signal processing; diffusion tensor mri; Medical informatics; Medicinsk informatik;

   Sammanfattning : We present a novel method for manifold learning, i.e. identification of the low-dimensional manifold-like structure present in a set of data points in a possibly high-dimensional space. The main idea is derived from the concept of Riemannian normal coordinates. LÄS MER

3. 22. Towards Effortless Use of Information Technology in Home Healthcare with a Networked Digital Pen

   Författare :Leili Lind; Hans Åhlfeldt; Daniel Karlsson; Bengt Fridlund; Sabine Koch; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Home care services; Hospital-based; Requirements; Pain Assessment; Visual Analogue Scale; Palliative care; Digital pens; Mobile phones; Internet; Medical informatics; Medicinsk informatik;

   Sammanfattning : When care is moved from the hospital to the home the demands for high quality care still remain. For problems arising from the geographical separation of patients and professional caregivers, information and communication technology may offer important solutions. LÄS MER

4. 23. Applications of Knowledge Discovery in Quality Registries - Predicting Recurrence of Breast Cancer and Analyzing Non-compliance with a Clinical Guideline

   Författare :Amir Reza Razavi; Nosrat Shahsavar; Arie Hasman; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast cancer; Clinical guidelines; Canonical correlation analysis; Data Mining; Data pre-processing; Decision tree induction; Knowledge Discovery in Databases; Medical informatics; Medicinsk informatik;

   Sammanfattning : In medicine, data are produced from different sources and continuously stored in data depositories. Examples of these growing databases are quality registries. In Sweden, there are many cancer registries where data on cancer patients are gathered and recorded and are used mainly for reporting survival analyses to high level health authorities. LÄS MER

5. 24. Advanced MRI Data Processing

   Författare :Joakim Rydell; Magnus Borga; Hans Knutsson; Göran Starck; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging MRI ; functional Magnetic Resonance Imaging fMRI ; spatial filtering; robust correlation estimation; correcting artifacts; Medical informatics; Medicinsk informatik;

   Sammanfattning : Magnetic resonance imaging (MRI) is a very versatile imaging modality which can be used to acquire several different types of images. Some examples include anatomical images, images showing local brain activation and images depicting different types of pathologies. LÄS MER

7. 25. Improving Assessments of Hemodynamics and Vascular Disease

   Författare :Magnus Ziegler; Petter Dyverfeldt; Tino Ebbers; Jonas Lantz; Ebo de Muinck; Carljohan Carlhäll; Alex J. Barker; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Blood vessels are more than simple pipes, passively enabling blood to pass through them. Their form and function are dynamic, changing with both aging and disease. This process involves a feedback loop wherein changes to the shape of a blood vessel affect the hemodynamics, causing yet more structural adaptation. LÄS MER
