1. 1. Classifying femur fractures using federated learning

   Master-uppsats, Linköpings universitet/Statistik och maskininlärning

   Författare :Hong Zhang; [2024]
   Nyckelord :Atypical femur fracture; Federated Learning; Neural Network; Classification;

   Sammanfattning : The rarity and subtle radiographic features of atypical femoral fractures (AFF) make it difficult to distinguish radiologically from normal femoral fractures (NFF). Compared with NFF, AFF has subtle radiological features and is associated with the long-term use of bisphosphonates for the treatment of osteoporosis. LÄS MER

3. 2. Rotfyllningskvalitet vid endodontiska behandlingar på studentklinik med utgångspunkt från kliniska och röntgenologiska parametrar.

   Master-uppsats, Malmö universitet/Odontologiska fakulteten (OD)

   Sammanfattning : Syfte: Att granska hur väl indikatorbilden och rotfyllningsbilden överensstämmer utifrån mätningar med elektronisk apexlokalisator. Dessutom granskas om rotfyllningskvalitet är beroende av tandtyp och antal besök samt om det förekommer någon skillnad på behandlingsproceduren före eller under COVID-19 pandemin. LÄS MER

4. 3. 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

5. 4. Segmentation of x-ray images using deep learning trained on synthetic data

   Master-uppsats, KTH/Fysik

   Författare :Marcus Larsson; [2023]
   Nyckelord :Radiography; Deep Learning; Synthetic Data; Segmentation; Röntgen; Djupinlärning; Syntetisk Data; Segmentering;

   Sammanfattning : Radiograph examinations play a critical role in various applications such as the detection of bone pathologies and lung cancer, despite the challenge of false negatives. The integration of Artificial Intelligence (AI) holds promise in enhancing image quality and assisting radiologists in their diagnostic processes. LÄS MER

7. 5. Factors related to vertical root fractures in teeth restored with prosthetic single crowns: A retrospective clinical study

   Master-uppsats, Malmö universitet/Odontologiska fakulteten (OD)

   Författare :Sham Al-Hotheiry; Mustafa Spahic; [2022]
   Nyckelord :Vertical root fracture;

   Sammanfattning : Purpose The aim of the present retrospective clinical study was to investigate the factors that could be associated with the occurrence of vertical root fractures regarding tooth-supported single crowns (VRF). Materials and methods This dental record-based retrospective study included patients treated with tooth-supported single crowns during from October 2008 to December 2010 at the Faculty of Odontology, Malmö University, Sweden.
