1. Estimating patient peak skin dose with fluoroscopic procedures
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : 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
2. Modeling of scatter radiation during interventional X-ray procedures
Master-uppsats, Linköpings universitet/Avdelningen för radiologiska vetenskaper; Linköpings universitet/Medicinska fakultetenSammanfattning : 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. LÄS MER
3. Dosimetry for the Lens of the Eye, Applications for Medical Staff Involved in Interventional Radiology Procedures
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : "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.

4. Entrance Skin Dose Measurement Using GafChromic Dosimetry Film for Patients Undergoing Coronary Angiography (CA) and Percutaneous Transluminal Coronary Angiography (PTCA) Procedures
Uppsats för yrkesexamina på grundnivå, Medicinsk strålningsfysik (tills m KI)Sammanfattning : Interventional radiological procedures often require long fluoroscopic exposure times and high levels of radiation exposure to patients, which often are higher than most radiological examinations except for computed tomography (CT) whose effective doses can be higher, and in addition to having radiation risks that are higher for both patient and medical staff. Therefore it is important to monitor and map the radiation entrance exposure to the patients, to minimize the probability of skin injury, and to detect areas of overlapping radiation fields. LÄS MER
