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

    Master-uppsats,

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

    Sammanfattning : 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. LÄS MER

  3. 2. Development of methods and software for rapid quality control in fluoroscopy

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Majid Khosamadi; [2021]
    Nyckelord :;

    Sammanfattning : Background: Fluoroscopy is a common imaging technique which uses X-ray to derive a real time imaging of patient anatomy to determine diagnosis and positioning of patients for interventional procedures. It is therefore important that the fluoroscopy systems maintain their performance. LÄS MER

  4. 3. Clinical outcomes after using of Rhythmia mapping system in patients with differentcomplex arrhythmias

    Master-uppsats, Örebro universitet/Institutionen för medicinska vetenskaper

    Författare :Hanna Ibrahim; [2021]
    Nyckelord :Cardiac arrhythmias; Radiofrequency ablation; Rhythmia mapping system; Electro-anatomical cardiac maps; Ablations outcomes.;

    Sammanfattning : Background: Rhythmia is a novel mapping system of cardiac arrhythmias, it utilizes a multielectrode catheter, Orion. Together these two instruments generate high accurate maps of the cardiac chamber which facilitate the identification of arrythmia focus and its ablation. LÄS MER

  5. 4. Radiation exposure to personnel during fluoroscopic procedures : Strålningsmiljö för personal under genomlysningsarbete

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Olof Eriksson; [2018]
    Nyckelord :;

    Sammanfattning : There are about 17 million X-ray procedures performed in Sweden every year. Various methods are used to determine the risk for the patient, and for the staff. LÄS MER

  7. 5. Estimating patient peak skin dose with fluoroscopic procedures

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Max Hellström; [2018]
    Nyckelord :skin dose; radiation dose structured reports; interventional radiology; radiation dosimetry;

    Sammanfattning : During image guided interventional radiology (IR) procedures, acute X-ray induced skin injuries may occur due to high absorbed patient skin dose. These procedures are highly dependent on X-ray imaging both for guiding fluoroscopy and high quality diagnostic image acquisitions. LÄS MER
