1. 1. Radiochromic Film Dosimetry in Kilovoltage X-­‐ray Beams: A Pre-­‐ Investigation for In Vitro Studies of Bystander Effects

   Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen; Lunds universitet/Medicinsk strålningsfysik, Lund

   Författare :Zeinab Hossein; [2015]
   Nyckelord :Medicine and Health Sciences;

   Sammanfattning : Purpose Intensity modulation of radiation is one of several important conditions to evaluate for full understanding of how cells involved in the bystander effect influence each other when cells are exposed to radiation at low and high dose rates. The aim of this study was to develop and apply a useful and practical dosimetric method for measurement of the absorbed dose to cell cultures exposed to intensity modulated radiation in investigations of the bystander effects.

3. 2. An investigation of a potential multipurpose readout modality for two and three-dimensional dosimetry using optical computed tomography scanners

   Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

   Författare :Henrik Svensson; [2011]
   Nyckelord :strålterapi; Medicine and Health Sciences;

   Sammanfattning : Radiochromic film, polymer gel and radiochromic plastic are three different kinds of dosimeters developed for radiation therapy. Even though all three types of dosimeters are suitable for optical scanning, the proposed readout method is different for each detector system. LÄS MER

4. 3. 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)

   Nyckelord :Interventional radiology; Maximum entrance skin dose; DAP; Reference dose; Radiochromic dosimetry film;

   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
