  1. 31. 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. 32. Machined surfaces as designed cell culture substrates

    University essay from Lunds universitet/Industriell Produktion

    Author : Kunal Sharma; [2021]
    Keywords : Surface topography; cell proliferation; cell adhesion; Technology and Engineering;

    Abstract : De flesta levande celler fäster på ytor av olika slag för att kunna växa, men vilka faktorer som bidrar till deras infästning på metallytor är hittills okänt. Man vet att ytans ojämnhet spelar en roll och att vissa material är cytotoxiska. READ MORE

  4. 33. 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

  5. 34. Synchrotron X-ray Tomography Study of Bone-implant Integration

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Ornella Lohéac; [2021]
    Keywords : Bone-implant; Digital volume correlation; Micro-computed tomography; PEEK; Synchrotron; Technology and Engineering;

    Abstract : Implant loosening is a recurring problem in the field of orthopedics, typically resulting in a physical and financial burden for the patient. Proper integration of orthopedic implants within host bones is a fundamental requirement for the successful function and limited risk of failure of implants which, in-vivo, must support various loading conditions.

  6. 35. Mechanical Properties of Calcium Phosphate and Additively Manufactured Titanium Alloy for Composite Spinal Implants

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

    Author : Josephine Lantz; [2021]
    Keywords : calcium phosphate; titanium; spinal implant; tensile testing; compression tests; 4-point-bending; finite element analysis; topology optimisation;

    Abstract : One of the major health problems in western societies is back pain, with a prevalence rate of 49%–80%. In many cases, the back pain is due to degenerated discs. The gold standard to treat a severely degenerated disc is spinal fusion, where the vertebral disc is replaced with a cage structure. READ MORE
