  3. 2. Lesion Segmentation in 3D FDG-PET/CT Scans Using Deep Learning

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Adam Maen; [2022]
    Keywords : ;

    Abstract : Drug development is an expensive, long and complex process for pharmaceutical companies all around the world. One way to make it more reliable is to evaluate the drug at its early stages, so the decision can be made to go forward or move to another drug, which is also a time-consuming and costly task to be done by human experts.

  4. 3. Pre-planning of Individualized Ankle Implants Based on Computed Tomography - Automated Segmentation and Optimization of Acquisition Parameters

    University essay from KTH/Fysik

    Author : Matilda Engström Messén; Elvira Moser; [2021]
    Keywords : osteochondral lesions of the talus; computed tomography; U-net; convolutional neural network; dice coefficient; fotled; ledbrosk; osteochondral lesion of the talus; datortomografi; U-net; convolutional neuralt nätverk; dicekoefficient;

    Abstract : The structure of the ankle joint complex creates an ideal balance between mobility and stability, which enables gait. If a lesion emerges in the ankle joint complex, the anatomical structure is altered, which may disturb mobility and stability and cause intense pain. READ MORE

  5. 4. Differences in tumor volume for treated glioblastoma patients examined with 18F-fluorothymidine PET and contrast-enhanced MRI

    University essay from Umeå universitet/Institutionen för fysik

    Author : Karolina Hedman; [2020]
    Keywords : PET MRI; positron emission tomography; magnetic resonance imaging; brain tumor; glioblastoma; image segmentation; adaptive thresholding; feature extraction; radiotracer; gadolinium; image processing; image analysis;

    Abstract : Background: Glioblastoma (GBM) is the most common and malignant primary brain tumor. It is a rapidly progressing tumor that infiltrates the adjacent healthy brain tissue and is difficult to treat. Despite modern treatment including surgical resection followed by radiochemotherapy and adjuvant chemotherapy, the outcome remains poor. READ MORE

  6. 5. Semi-supervised Lesion Detection via Image Restoration

    University essay from Lunds universitet/Matematik LTH

    Author : Jonatan Kronander; [2020]
    Keywords : Mathematics and Statistics;

    Abstract : Lesion detection is a critical task for medical image understanding. While the problem has been widely addressed in a supervised semantic segmentation manner, the problem clinically appears more similar to novelty detection with few or no annotations for the lesion. READ MORE
