  1. 11. 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

  3. 12. Image inpainting methods for elimination of non-anatomical objects in medical images

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

    Author : Andrea Lorenzo Polo; [2021]
    Keywords : Medical Imaging; Tumor Ablation; Inpainting; U-Net; Convolutional Neural Network;

    Abstract : This project studies the removal of non-anatomical objects from medical images. During tumor ablation procedures, the ablation probes appear in the image, hindering the performance of segmentation, registration, and dose computation algorithms. These algorithms can also be affected by artifacts and noise generated by body implants. READ MORE

  4. 13. Automatic magnetic resonance brain volume measurements to assess the effect of minimised blood sample extraction on brain development in extremely preterm infants

    University essay from Lunds universitet/Läkarutbildningen

    Author : Hickmat Hamie; [2021]
    Keywords : Magnetic resonance imaging; Brain development; Prematurity; Medicine and Health Sciences;

    Abstract : Aim: To evaluate a pipeline for automatic MRI brain segmentation and volumetric tissue structure quantification in a cohort of extremely preterm infants. Methods: 13 extremely preterm neonates underwent MRI-scanning at a term equivalent age. Seven of these subjects had suitable MRI sequences and were analyzed in the pipeline. READ MORE

  5. 14. Automated 3D Bone Segmentation using Deep Learning in Scoliosis

    University essay from Lunds universitet/Matematik LTH

    Author : Andreas Bennström; Filip Winzell; [2021]
    Keywords : Deep learning; Scoliosis; U-net; Bone segmentation; Image segmentation; Semantic segmentation; Computed Tomography; Mathematics and Statistics;

    Abstract : Background: Scoliosis is a condition where a person's spine is curved and rotated in three dimensions. In severe cases, surgery is needed to straighten the spine. Before such complex procedures, meticulous planning is needed. By performing a CT-scan, images of the spine can be acquired. READ MORE

  6. 15. Semi-Supervised Deep Learning using Consistency-Based Methods for Segmentation of Medical Images

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

    Author : Axel Rönnberg; [2020]
    Keywords : ;

    Abstract : In radiation therapy, a form of cancer treatment, accurately locating the anatomical structures is required in order to limit the impact on healthy cells. The automatic task of delineating these structures and organs is called segmentation, where each pixel in an image is classified and assigned a label. READ MORE
