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

    University essay from KTH/Fysik

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

    Abstract : 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. READ MORE

  3. 2. Continual Learning and Biomedical Image Data : Attempting to sequentially learn medical imaging datasets using continual learning approaches

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Davit Soselia; [2022]
    Keywords : Deep Learning; Continual Learning; Catastrophic Forgetting; Biomedical Image Classification; Djup inlärning; kontinuerligt lärande; katastrofal glömska; biomedicinsk bildklassificering;

    Abstract : While deep learning has proved to be useful in a large variety of tasks, a limitation remains of needing all classes and samples to be present at the training stage in supervised problems. This is a major issue in the field of biomedical imaging since keeping samples in the training sets consistently is often a liability. READ MORE

  4. 3. Material decomposition using a photon counting X-ray detector in low energy range

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Rasmus Solem; [2021]
    Keywords : Medicine and Health Sciences;

    Abstract : Material decomposition in X-ray imaging is used to separate different materials or elements in an image and to quantify their respective concentration. The material decomposition and quantification are made possible by the dependency of attenuation on the attenuating material and photon energy. READ MORE
