  1. 11. Image analysis on the structure of the Achilles tendon

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Linnea Andersson; [2022]
    Keywords : biomechanics; Achilles tendon; image analysis; image processing; tendons; synchrotron; computed tomography; phase contrast; Technology and Engineering;

    Abstract : The Achilles tendon is the largest tendon of the human body which makes injuries of it very painful and incapacitating. A common factor of the pain are heterotopic ossifications, which are mineral deposits occurring inside the normal tendon tissue. Why and how heterotopic ossifications occur are somewhat unknown.

  3. 12. Neural Networks for Material Decomposition in Photon-Counting Spectral CT

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Hugo Charrier; [2022]
    Keywords : PCCT; X-ray; scanner; photon counting; AI; neural networks;

    Abstract : Photon counting computed tomography scanners constitute a major improvement of the field of computed tomography, opening various prospective and enabling the decomposition of computed tomography images into different materials. The material decomposition algorithm, mapping photon counts to material pathlengths, relies on a forward model with Poisson statistics. READ MORE

  4. 13. Assessment of hip deformities during childhood: a combined approach of Machine Learning and Finite Element Analysis

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Klara Eriksson; Jonna Fahrman; [2022]
    Keywords : Biomechanics; Hip joint; Cartilage; Osteoarthritis; Machine learning; Finite element analysis; Technology and Engineering;

    Abstract : Osteoarthritis is a degenerative disease that will cause pain and stiffness in the joint if not treated. One cause of early osteoarthritis in the hip joint is pediatric hip deformities. Hip deformities can occur in different stages of childhood and cause the bones to be misshapen or the hip joint to be dislocated. READ MORE

  5. 14. Rapid Preparation of Soft Tissue for X-ray Virtual Histology

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

    Author : Filip Lagerqvist; [2022]
    Keywords : Phase-contrast computed tomography; fixation; fixation time; image segmentation; tumor resection margin;

    Abstract : When removal of primary tumors is performed by surgery, the surgeon andthe patient would benefit from using intraoperative feedback to evaluate thetumor resection margin. If intraoperative feedback is not provided there isadditional risk of treatment of the tumor. READ MORE

  6. 15. High resolution x-ray imaging by measuring the induced charge distribution

    University essay from KTH/Fysik

    Author : Zihui Jin; [2022]
    Keywords : Computed tomography; photon-counting detector; silicon; spatial resolution; Datortomografi; fotonräknande detektor; kisel; spatial upplösning;

    Abstract : Computed tomography (CT) is a medical imaging technique used to create cross-section images of human bodies based on x-rays. The emerging photon-counting CT detector shows several advantages compared with the traditional energy integrating detector. READ MORE
