  1. 1. Estimating patient peak skin dose with fluoroscopic procedures

    University essay from Umeå universitet/Institutionen för fysik

    Author : Max Hellström; [2018]
    Keywords : skin dose; radiation dose structured reports; interventional radiology; radiation dosimetry;

    Abstract : 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. READ MORE

  3. 2. Validation of simulation tool for C-arm X-ray systems : Source and scatter model

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Martina Jurcova; [2016]
    Keywords : Simulation; C-arm system; X-ray imaging; focal spot; scattering; image sharpness;

    Abstract : Continuous improvement of image quality is one of the priorities in medical imaging. Therefore, development of a simulation tool allowing to generate realistic images would be of great value to understand better the impact of the components on the image quality metrics and to choose imaging set-ups or new design features to optimize output of existing systems and to prototype new ones and to formalize the link between objective and subjective image quality metrics.

  4. 3. Modeling of scatter radiation during interventional X-ray procedures

    University essay from Linköpings universitet/Avdelningen för radiologiska vetenskaper; Linköpings universitet/Medicinska fakulteten

    Author : Emelie Rehn; [2015]
    Keywords : medical staff; personnel; practitioner; staff exposure; physician; operator; occupational exposure; radiation protection; protection in medical x-ray imaging; x-ray exposure; radiation dose; radiation scatter; fluoroscopy; interventional x-ray procedures; interventional radiology; angiography; fluoroscopically guided procedures; interventional radiology dosimetry; interventional cardiology dosimetry; catheterization interventions;

    Abstract : During catheterized x-ray interventions the patient and medical staff is exposed to scatter radiation, as a consequence of tissue interactions. Ionizing radiation for medical purpose is potentially dangerous and can cause malignancy, skin damage and more. READ MORE

  5. 4. Staff dose measurement in real time, an evaluation of Unfors Raysafe i2

    University essay from Institutionen för fysik

    Author : Mehdi Khosravinia; [2013]
    Keywords : Unfors Raysafe i2;

    Abstract : Interventional radiology workers job involves exposure to ionizing radiation. In Sweden monitoring the accumulated dose to the personnel in professions, which involves with ionizing radiation, is mandatory. There are many applications that can visualize and measure the accumulated dose of the personnel. READ MORE

  6. 5. Dosimetry for the Lens of the Eye, Applications for Medical Staff Involved in Interventional Radiology Procedures

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Therese Geber; [2010]
    Keywords : Röntgen; Medicine and Health Sciences;

    Abstract : "Background: Cataract (opacity of the lens of the eye) has always been thought of as a deterministic effect. That is, that there is a threshold dose below which damage does not occur. However, recent studies suggest a lower threshold and the question whether there is any threshold at all has been raised. READ MORE
