  1. 11. Dielectric Characterization of Bone Using Ultra Wide Band Microwave Transmission Probe

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Abhinav Singh; [2022]
    Keywords : ;

    Abstract : The body has the capability of reabsorbing and generating new bone throughout life. Bone remains healthy as long it maintains the equal amount of old and new bones. Bone loss is occurred when the old bone absorbed is more and new bone created is less. Osteoporosis is a very common bone disease among men and women in their later years. READ MORE

  3. 12. 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. 13. Evaluation of the impact of reduced scan field-of-view (SFOV) on CT radiation dose and image quality in a chest CT – a phantom study

    University essay from Örebro universitet/Institutionen för hälsovetenskaper

    Author : Fleury Ndongozi; [2022]
    Keywords : ;

    Abstract : Background: Technical development of image detectors and dose-reduction techniques in computed tomography (CT) have contributed to reduce radiation dose for patient and staff. The scan field of view (SFOV) generally affects the radiation dose the patient will beexposed. READ MORE

  5. 14. Micro-CT based finite element models for mechanical strength assessment of glass ceramic scaffolds obtained through the robocasting technique

    University essay from KTH/Hållfasthetslära

    Author : Gustav Thessén; [2022]
    Keywords : µ-CT modelling; phase-field method; bio-glass scaffolds; strength assessment; Mikrotomografi; μ-CT; fasfältsmetoden; bio-glas stödstrukturer; brottgräns;

    Abstract : In this thesis, micro computed tomography (μ−CT) scans of a bio-glass scaffold produced by the robocasting technique was used to create finite element method (FEM) models with the purpose of determining its mechanical strength. Prior to this, a Matlab script was used to create several simplified geometries of the scaffold in an effort to determine the importance of scaffold design parameters (such as the fiber compenetration between two adjacent printing planes) on the strength of the scaffold.

  6. 15. FETAL DOSE ESTIMATION IN ABDOMINAL AND PELVIC CT EXAMINATIONS

    University essay from

    Author : Olivia Carlstein; [2021-05-10]
    Keywords : Medical physics; Fetal dose; abdominal CT examination; pelvic CT examination; phantom measurement;

    Abstract : Purpose: The purpose of this is study was to compare different methods for estimating the fetal dose, how much the different methods differ from each other and on which dose levels the fetal doses are estimated to. Theory: A radiological procedure should always be justified and in the case of a pregnant patient the justification should include both the mother and the fetus. READ MORE
