  1. 1. Deep Learning-Based Bone Segmentation of the Metatarsophalangeal Joint : Using an Automatic and an Interactive Approach

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Hannah Krogh; [2023]
    Keywords : Deep Learning; CNN; U-Net; DeepEdit; Bone Segmentation; CT; MTP Joint;

    Abstract : The first Metatarsophalangeal (MTP) joint is essential for foot biomechanics and weight-bearing activities. Osteoarthritis in this joint can lead to pain, discomfort, and limited mobility. In order to treat this, Episurf Medical is working to produce individualized implants based on 3D segmentations of the joint. READ MORE

  3. 2. Imaging of the MTP joint: Developing an imaging protocol optimised for damage detection and 3D modelling

    University essay from KTH/Fysik

    Author : Johanna Jacobsson; [2022]
    Keywords : computed tomography; magnetic resonance imaging; cone beam computedtomography; cartilage; osteochondral lesions; metatarsal phalangeal joint; datortomografi; magnetisk resonanstomografi; kon-datortomografi; brosk; kondrala skador; metatarsalphalangen-leden;

    Abstract : Walking without pain in the toe has a significant impact on a person’s well-being. Human mobility will be impaired in osteoarthritis of the big toe, and pain will occur during walking. By replacing the cartilage or bone injury with an individualised implant, osteochondral injuries to the knee and ankle can be treated. READ MORE

  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. Deep Learning-Based Automated Segmentation and Detection of Chondral Lesions on the Distal Femur

    University essay from KTH/Fysik

    Author : Josefin Lindemalm Karlsson; [2019]
    Keywords : Deep Learning; Machine Learning; automated segmentation; MRI; chondral lesions; articular cartilage; Deep Learning; Maskininlärning; automatiserad segmentering; MRI; broskskador; ledbrosk;

    Abstract : Articular chondral lesions in the knee joint can be diagnosed at an early stage using MRI. Segmenting and visualizing lesions and the overall joint structure allows improved communication between the radiologist and referring physician. It can also be of help when determining diagnosis or conducting surgical planning. READ MORE

  6. 5. T2 Mapping Compared to Standard MRI Assessment : An Assessment of the Knee Cartilage on Distal Femur

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Jennie Andersson; [2019]
    Keywords : MRI; T2-mapping; articular cartilage; distal femur; knee; MR; T2-mapping; ledbrosk; distala lårbenet; knä;

    Abstract : Magnetic resonance imaging (MRI) has become the most important modality for assessment of pathological changes in the knee cartilage. The assessment of the cartilage is usually made by a set of anatomical MRI images with different sequences. READ MORE
