1. 1. Developing a highly accurate, locally interpretable neural network for medical image analysis

   Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

   Författare :Rony David Ventura Caballero; [2023]
   Nyckelord :XAI; Interpretability; Computer vision; Pediatric pneumonia; Chest radiograph;

   Sammanfattning : Background Machine learning techniques, such as convolutional networks, have shown promise in medical image analysis, including the detection of pediatric pneumonia. However, the interpretability of these models is often lacking, compromising their trustworthiness and acceptance in medical applications. LÄS MER

3. 2. Image Segmentation Using Deep Learning Regulated by Shape Context

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Wei Wang; [2018]
   Nyckelord :U-net; deep learning; Shape Context; Shape Model; segmentation; chest radiograph; Chest X-ray;

   Sammanfattning : In recent years, image segmentation by using deep neural networks has made great progress. However, reaching a good result by training with a small amount of data remains to be a challenge. LÄS MER

4. 3. Effect of image variation on computer aided detection systems

   Master-uppsats, KTH/Skolan för teknik och hälsa (STH)

   Författare :Seyedeh Parisa Rabbani; [2013]
   Nyckelord :Chest radiograph normalization; local normalization; multi band local normalization;

   Sammanfattning : Computer Aided Detection (CAD) systems are expecting to gain significant importance in terms of reducing the work load of radiologists and enabling the large screening programs. A large share of CAD systems are based on learning from examples, to enables the decision making between the images with or without disease. LÄS MER

5. 4. Digital Tomosynthesis Fundamental principles and comparison to conventional X-ray imaging

   Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

   Författare :Christian Bernhardsson; [2006]
   Nyckelord :Röntgen; Medicine and Health Sciences;

   Sammanfattning : During the last century several attempts have been made to overcome the fundamental problem of X-ray imaging, i.e. that anatomical information existing in 3-dimensions has to be represented on a 2-dimensional radiograph. In this thesis, digital tomosynthesis, a rened version of conventional tomography, has been investigated. LÄS MER
