  1. 11. 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

  3. 12. 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

  4. 13. EVALUATION OF RADIATION DOSES USING CONE BEAM COMPUTED TOMOGRAPHY IN ENDOVASCULAR AORTIC REPAIR AND SCOLIOSIS PROCEDURES

    University essay from

    Author : Louise Strandberg; [2021-04-06]
    Keywords : Medical physics; Cone beam CT; CT; EVAR; scoliosis; radiation dose; effective dose;

    Abstract : Purpose: The study includes the two areas, vascular surgery and orthopedics, and focuses on endovascular aortic aneurysm repair (EVAR) and scoliosis procedures. EVAR procedures contribute to a high radiation dose to the patient and for scoliosis procedures, it is often young girls that are undergoing surgery. READ MORE

  5. 14. 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. 15. Learning the Forward Operator in Photon-Counting Computed Tomography

    University essay from KTH/Matematik (Avd.)

    Author : Emanuel Ström; [2021]
    Keywords : Photon-Counting; Computed Tomography; Spectral CT; Regularisation; Deep Learning; Fotonräknande; Datortomografi; Spektral CT; Regularisering; Djupinlärning;

    Abstract : Computed Tomography (CT) is a non-invasive x-ray imaging method capable of reconstructing highly detailed cross-sectional interior maps of an object. CT is used in a range of medical applications such as detection of skeletal fractures, organ trauma and artery calcification. READ MORE
