   Sammanfattning : Syfte: Att granska hur väl indikatorbilden och rotfyllningsbilden överensstämmer utifrån mätningar med elektronisk apexlokalisator. Dessutom granskas om rotfyllningskvalitet är beroende av tandtyp och antal besök samt om det förekommer någon skillnad på behandlingsproceduren före eller under COVID-19 pandemin. LÄS MER

3. 2. Uncertainties in the use of synthetic CT (sCT) for daily online adaptive radiotherapy for lung cancer

   Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

   Författare :Johansson Vivika; [2023]
   Nyckelord :Medicine and Health Sciences;

   Sammanfattning : Background and purpose: Cone Beam Computed Tomography (CBCT) based online adaptive radiotherapy (oART) has been clinically implemented for several anatomical sites worldwide. However, random and abrupt anatomical changes with large density alterations can occur in lung patients, leading to uncertainties with synthetic computed tomography (sCT) and dose calculation.

4. 3. Factors related to vertical root fractures in teeth restored with prosthetic single crowns: A retrospective clinical study

   Master-uppsats, Malmö universitet/Odontologiska fakulteten (OD)

   Författare :Sham Al-Hotheiry; Mustafa Spahic; [2022]
   Nyckelord :Vertical root fracture;

   Sammanfattning : Purpose The aim of the present retrospective clinical study was to investigate the factors that could be associated with the occurrence of vertical root fractures regarding tooth-supported single crowns (VRF). Materials and methods This dental record-based retrospective study included patients treated with tooth-supported single crowns during from October 2008 to December 2010 at the Faculty of Odontology, Malmö University, Sweden.

5. 4. Assessment of hip deformities during childhood: a combined approach of Machine Learning and Finite Element Analysis

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Klara Eriksson; Jonna Fahrman; [2022]
   Nyckelord :Biomechanics; Hip joint; Cartilage; Osteoarthritis; Machine learning; Finite element analysis; Technology and Engineering;

   Sammanfattning : Osteoarthritis is a degenerative disease that will cause pain and stiffness in the joint if not treated. One cause of early osteoarthritis in the hip joint is pediatric hip deformities. Hip deformities can occur in different stages of childhood and cause the bones to be misshapen or the hip joint to be dislocated. LÄS MER

7. 5. Material decomposition using a photon counting X-ray detector in low energy range

   Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

   Författare :Rasmus Solem; [2021]
   Nyckelord :Medicine and Health Sciences;

   Sammanfattning : Material decomposition in X-ray imaging is used to separate different materials or elements in an image and to quantify their respective concentration. The material decomposition and quantification are made possible by the dependency of attenuation on the attenuating material and photon energy. LÄS MER
