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. 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

4. 3. 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

5. 4. Entrance Skin Dose Measurement Using GafChromic Dosimetry Film for Patients Undergoing Coronary Angiography (CA) and Percutaneous Transluminal Coronary Angiography (PTCA) Procedures

   University essay from Medicinsk strålningsfysik (tills m KI)

   Author : Nabil Iqeilan; [2007]
   Keywords : Interventional radiology; Maximum entrance skin dose; DAP; Reference dose; Radiochromic dosimetry film;

   Abstract : 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. READ MORE
