  1. 11. Faraday cage för förvaring av hemelektronik och EMF-dämpning

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Arianne Östlund; [2023]
    Nyckelord :;

    Sammanfattning : Elektromagnetiska fält (EMF) finns överallt. De är naturligt förekommande, men teknik orsakar allt fler konstgjorda fält i olika styrkor ovanpå dessa. LÄS MER

  3. 12. CHARACTERIZATION AND EVALUATION OF A NIPAM POLYMER GEL MRI DOSIMETER SYSTEM

    Master-uppsats,

    Författare :Christian Waldenberg; [2022-11-08]
    Nyckelord :Medical physics; Normoxic polymer gel dosimeter; NiPAM;

    Sammanfattning : Purpose: The normoxic polymer gel dosimeter based on N-isopropyl acrylamide (NiPAM) is a promising full 3D-dosimeter with high spatial resolution and near tissue equivalency. However, limited work have been done in vestigating this dosimeter. The dose response and reproducibility of a NiPAM dosimeter was investigated. LÄS MER

  4. 13. Models for estimating radiation dose and LAR from radioactive fallout: extended dose algorithms for the computational tool LARCalc

    Master-uppsats,

    Författare :Jonathan Sundström; [2022-09-09]
    Nyckelord :Medical physics; Nuclear power plant; Radiation dose; Effective dose; Lifetime attributable risk; LAR; Fallout; Inhalation; Strontium-90; Iodine-131; Cloudshine;

    Sammanfattning : Today, emergency preparedness is needed against both nuclear reactor accidents and nuclear weapons fallout. Both scenarios can lead to exposure of ionizing radiation. Upon exposure, radionuclides will incur a radiation dose both internally and externally. LÄS MER

  5. 14. osimetric impact of system spe cific geometric distortion on head and neck treatment plans in MRI only based radiation therapy

    Master-uppsats,

    Författare :Jesper Brovall; [2022-01-13]
    Nyckelord :Medical physics; Dosimetry; MRI; Radiation therapy;

    Sammanfattning : Background/ purpose: Because of the superior soft tissue contrast, in comparison with computed tomography (CT) data, magnetic resonance imaging (MRI) is of high interest to include in a larger extent in the ra diation therapy (RT) process. In an MRI only workflow, the CT scan is excluded and a synthetic CT is used for treatment plan ning. LÄS MER

  7. 15. Dielectric Characterization of Bone Using Ultra Wide Band Microwave Transmission Probe

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Abhinav Singh; [2022]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER
