2. 1. Improving Multi-Atlas Segmentation Methods for Medical Images

   Author : Jennifer Alvén; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supervised learning; semantic segmentation; multi-atlas segmentation; conditional random fields; label fusion; feature-based registration; image registration; random decision forests; convolutional neural networks; medical image segmentation;

   Abstract : Semantic segmentation of organs or tissues, i.e. delineating anatomically or physiologically meaningful boundaries, is an essential task in medical image analysis. One particular class of automatic segmentation algorithms has proved to excel at a diverse set of medical applications, namely multi-atlas segmentation. READ MORE

4. 2. Combining Shape and Learning for Medical Image Analysis

   Author : Jennifer Alvén; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; feature-based registration; convolutional neural networks; conditional random fields; medical image segmentation; random decision forests; machine learning; multi-atlas segmentation; medical image registration; shape models;

   Abstract : Automatic methods with the ability to make accurate, fast and robust assessments of medical images are highly requested in medical research and clinical care. Excellent automatic algorithms are characterized by speed, allowing for scalability, and an accuracy comparable to an expert radiologist. READ MORE

5. 3. Analysis of Medical Images : Registration, Segmentation and Classification

   Author : Matilda Landgren; Mathematical Imaging Group; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : A large number of medical examinations involve images in some way. Images can be used for diagnostics, follow-up studies and treatment planning. In this thesis mathematical methods have been developed and adapted in order to analyze medical images. READ MORE

6. 4. Quantitative Muscle Composition Analysis Using Magnetic Resonance Imaging

   Author : Anette Karlsson; Magnus Borga; Anneli Peolsson; Janne West; Todd Parrish; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Muscle Composition; Muscle fat Infiltration; Magnetic Resonance Imaging;

   Abstract : Changes in muscle tissue composition, e.g. decrease in volume and/or increase of fat infiltration, are related to adverse health conditions such as sarcopenia, inflammation, muscular dystrophy, and chronic pain. READ MORE

7. 5. Fat-Referenced MRI : Quantitative MRI for Tissue Characterization and Volume Measurement

   Author : Thobias Romu; Magnus Borga; Olof Dahlqvist Leinhard; Samir Sharma; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; water-fat separation; quantitative MRI;

   Abstract : The amount and distribution of adipose and lean tissues has been shown to be predictive of mortality and morbidity in metabolic disease. Traditionally these risks are assessed by anthropometric measurements based on weight, length, girths or the body mass index (BMI). READ MORE
